Local code execution in NVIDIA NVTabular allows an authenticated low-privileged user to abuse improper deserialization of untrusted data to run arbitrary code, tamper with data, and disclose sensitive information. The CVSS 3.1 base score is 7.8 (AV:L/AC:L/PR:L/UI:N) reflecting a local attack vector with low complexity and low privileges; no public exploit identified at time of analysis and the issue is not on the CISA KEV list.
PHP object injection in the Elated-Themes Askka WordPress theme through version 1.3.1 allows remote attackers to deserialize untrusted data, potentially leading to arbitrary code execution, file manipulation, or full site compromise depending on available gadget chains. The CVSS score of 8.1 reflects high impact across confidentiality, integrity, and availability, though high attack complexity (AC:H) tempers immediate exploitability. No public exploit identified at time of analysis.
PHP object injection in the Elated-Themes Töbel WordPress theme (versions up to and including 1.8.1) allows remote attackers to trigger unsafe deserialization of attacker-controlled data, potentially leading to arbitrary code execution, file manipulation, or data tampering depending on available POP gadgets. Rated CVSS 8.1 (High) with no public exploit identified at time of analysis and no CISA KEV listing, though the network attack vector and lack of authentication requirement make it a meaningful risk to any WordPress site running the theme.
Object injection in the Elated-Themes Aperitif WordPress theme through version 1.6 allows remote attackers to trigger PHP deserialization of attacker-controlled data, potentially leading to code execution, file manipulation, or full site compromise when a suitable gadget chain is present. CVSS 8.1 reflects high impact across confidentiality, integrity, and availability, though attack complexity is rated High. No public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Remote code execution in Microsoft SharePoint Server (2016 Enterprise, 2019, and Subscription Edition) allows an authenticated attacker to execute arbitrary code on the server by submitting crafted serialized data that triggers unsafe deserialization. The CVSS 8.0 vector requires low privileges and user interaction, and no public exploit is identified at time of analysis. The flaw is significant because SharePoint servers typically run with high privileges inside enterprise environments and frequently host sensitive collaboration data.
Remote code execution in IBM WebSphere Application Server 9.0 and 8.5 allows authenticated attackers to abuse unsafe Java deserialization in the SAML Web Single Sign-On component to run arbitrary code via a crafted HTTP request combined with a gadget chain. The flaw carries a CVSS 8.5 with scope change, and while no public exploit has been identified at time of analysis, deserialization gadget chains for WebSphere are historically well-researched. IBM has released a patch via support advisory node/7274733.
Remote code execution in IBM WebSphere Application Server 9.0 and 8.5 arises from unsafe deserialization of untrusted data processed by JAX-WS endpoints that use WS-Security. Unauthenticated remote attackers who can reach a SOAP/JAX-WS endpoint may craft malicious serialized payloads to execute arbitrary code in the WebSphere server context. No public exploit identified at time of analysis, but the high CVSS (9.0) and scope-changed impact mean any exposed JAX-WS service is a meaningful target.
Remote code execution in AMD's AI Tensor Engine for ROCm (AITER) through version 0.1.14 allows unauthenticated network attackers to run arbitrary code on every inference worker in a distributed cluster by sending a malicious pickle payload to the ZMQ SUB socket consumed by MessageQueue.recv() in shm_broadcast.py. The vulnerability stems from unauthenticated, unvalidated pickle deserialization with no HMAC or format checks; no public exploit identified at time of analysis, but VulnCheck has published an advisory and AMD has merged an upstream fix.
Unauthenticated remote code execution in Dassault Systèmes Teamwork Cloud (No Magic Release 2022x-2026x) and Magic Collaboration Studio (CATIA Magic Release 2022x-2026x) arises from unsafe deserialization of attacker-controlled data. The CVSS 9.8 vector indicates a network-reachable attack with no privileges or user interaction, yielding full confidentiality, integrity, and availability impact, though no public exploit identified at time of analysis and EPSS data was not provided.
Arbitrary code execution in ESA AnomalyMatch before 1.3.1 allows local attackers with low privileges to run code under the application's process by planting a malicious PyTorch checkpoint into a session directory, which is loaded via torch.load() with weights_only=False. No public exploit is identified at time of analysis, but the upstream fix (PR #9) and a third-party advisory (imlabs.info) confirm the unsafe-deserialization root cause and the migration to safetensors.
Arbitrary Python module import in Apache Airflow versions prior to 3.2.2 occurs when the scheduler deserializes custom DeadlineReference objects, because the prior implementation called import_string() directly on an attacker-controllable __class_path field. Rated CVSS 7.3 with low confidentiality/integrity/availability impact, this issue has no public exploit identified at time of analysis and EPSS estimates exploitation probability at 0.02% (6th percentile).
Authenticated remote code execution in Apache Airflow 3.2.0 through 3.2.1 allows users with permission to update XCom entries to achieve code execution by submitting reserved deserialization metadata keys (e.g. __classname__, __type, __data__, __var) to the PATCH XCom endpoint. The XComUpdateBody datamodel omitted the FORBIDDEN_XCOM_KEYS validator that XComCreateBody enforced, letting attackers smuggle a malicious typed payload that is later deserialized into an arbitrary Python class. No public exploit identified at time of analysis and EPSS risk is negligible (0.02%), but a vendor fix has shipped and the root cause is a classic CWE-502 untrusted deserialization.
Remote code execution in manga-image-translator's share.py API server allows unauthenticated attackers to achieve full container compromise via unsafe pickle deserialization. The /execute/{method_name} and /simple_execute/{method_name} endpoints deserialize attacker-controlled request bodies with pickle.loads(), enabling arbitrary code execution in the server process. Publicly available exploit code exists, but the EPSS score (0.36%) indicates low current exploitation probability.
Remote code execution in SMSGate sms-core versions 2.1.13.6 and earlier allows remote attackers to execute arbitrary code by sending crafted input to the Cmpp7FDeliverRequestMessageCodec.java component, which handles CMPP protocol message decoding. The CVSS 7.3 (AV:N/AC:L/PR:N/UI:N) vector indicates network-reachable, unauthenticated exploitation with low complexity, though EPSS scores this at only 0.06% (18th percentile) and there is no public exploit identified at time of analysis. SSVC indicates exploitation status is 'none' but the issue is automatable with partial technical impact across CIA.
Arbitrary file deletion in the WP Contact Form 7 DB Handler WordPress plugin (versions up to and including 3.0) can be achieved by chaining CSRF, UNION-based SQL injection, and PHP object deserialization. A remote unauthenticated attacker who lures a logged-in administrator to a malicious page can delete arbitrary server files, including wp-config.php, which typically forces the site into a re-installation state and enables full site takeover. No public exploit identified at time of analysis, though Wordfence's detailed write-up effectively documents the exploit chain.
Unauthenticated PHP object deserialization in Symfony's Monolog Bridge affects the development-time `server:log` console command, which by default binds its TCP log listener to 0.0.0.0:9911 and passes every received frame through `unserialize(base64_decode(...))` with no allowed_classes allowlist, authentication, or integrity check. Any host that can reach port 9911 on a machine running `server:log` can crash the listener (unauthenticated DoS) or trigger PHP object injection whose magic-method side effects may reach remote code execution when a usable gadget chain exists in the target's autoload set. No public exploit identified at time of analysis; EPSS is low (0.99%, 77th percentile) and the flaw is not in CISA KEV, consistent with a dev-only tool rather than a production-facing service.
Remote code execution in RELATE LMS (the inducer/relate web courseware platform) stems from its Celery task queue being configured to accept and unpickle untrusted messages (CELERY_ACCEPT_CONTENT included "pickle"). Because the code-execution sandbox lacks network isolation, an authenticated student can reach the message broker and deliver a malicious pickle payload that the worker deserializes, yielding arbitrary command execution on the host. No public exploit identified at time of analysis; the issue is corrected in commit d66ba5659b459bf1ba56b7109b5f9ecf197cbefb.
PHP object injection in Pimcore (packages pimcore/pimcore and admin-ui-classic-bundle) up to and including version 12.3.6 arises from six code paths calling unserialize() without the allowed_classes restriction on values read from database columns and filesystem files. An attacker who can already write to one of those sources - for example through SQL injection into the tmp_store, sites, or custom_layouts tables, or a file write to the WebDAV delete log - can plant a serialized PHP gadget chain that executes arbitrary code with web-server privileges once the data is deserialized. No public exploit identified at time of analysis (the vendor advisory documents only a conceptual PoC procedure), the CVE is not in CISA KEV, and EPSS is not provided; the issue is fixed in 12.3.7 and rated CVSS 8.0, with the High attack-complexity reflecting its dependence on a separate write primitive and a working gadget chain.
SQL injection in Pimcore's admin-ui-classic-bundle (versions <= 2.3.5) allows an authenticated user holding only the translations-view permission to read arbitrary database contents by injecting into the translation grid's date filter. The user-controlled 'property' field of the filter JSON is interpolated directly into a UNIX_TIMESTAMP(DATE(FROM_UNIXTIME(...))) expression at the POST /admin/translation/translations endpoint, behind only a trivially bypassable str_replace('--','') filter. A working proof-of-concept and publicly available exploit code exist; the reporter notes it can be chained with an unsafe-unserialize flaw (GM-249) to reach remote code execution. No EPSS score or CISA KEV listing was supplied.
Insecure deserialization in NVIDIA Merlin Transformers4Rec on Linux allows a local attacker to achieve code execution, data tampering, and information disclosure by tricking a user into loading a malicious serialized object. The flaw affects all Main-branch commits prior to March 11, 2026, and currently has no public exploit identified at time of analysis, with a very low EPSS score (0.02%) reflecting limited real-world activity. CISA SSVC classifies exploitation as 'none' but technical impact as 'total', placing it firmly in the supply-chain/MLOps risk category rather than a mass-exploitation threat.
Remote code execution in Mirasvit Full Page Cache Warmer for Magento 2 before 1.11.12 allows unauthenticated attackers to execute arbitrary code by sending a crafted serialized PHP object in the CacheWarmer cookie. The flaw is confirmed actively exploited (CISA KEV) with publicly available exploit code, and successful exploitation chains Magento and dependency gadget chains via an unsafe call to unserialize(). Despite a low EPSS score (0.10%), KEV listing and CVSS 9.3 indicate this is a high-priority patch for any Magento 2 store running the module.
Remote code execution in HuggingFace Transformers prior to 5.3.0 allows attackers to achieve arbitrary code execution on a victim's machine by publishing a malicious model whose config.json sets the `_attn_implementation_internal` field to an attacker-controlled Hub repository. When the victim calls the standard `AutoModelForCausalLM.from_pretrained()` API, the library silently downloads and executes Python kernels from that repository with the victim's privileges, bypassing the `trust_remote_code` safety gate. No public exploit is identified at time of analysis (EPSS 0.03%, SSVC exploitation: none), but the technical impact is total and the attack uses the documented, default usage pattern.
Information disclosure in Microsoft Planetary Computer Pro (GeoCatalog) lets a remote, unauthenticated attacker read sensitive data by sending crafted serialized objects that the service deserializes without validation (CWE-502). The flaw carries a CVSS 3.1 score of 7.5 (confidentiality-only impact) and, per SSVC, is automatable but has no observed exploitation; there is no public exploit identified at time of analysis, and EPSS estimates a low 0.27% probability of exploitation in the next 30 days.
Authenticated remote code execution in Microsoft SharePoint (Enterprise Server 2016, Server 2019, and Subscription Edition) stems from unsafe deserialization of untrusted data (CWE-502), enabling an authorized attacker to run arbitrary code on the server over the network. CVSS 8.8 with low privileges required and no user interaction makes this attractive to post-authentication adversaries, though no public exploit identified at time of analysis and CVSS temporal data marks exploit code maturity as Unproven.
Arbitrary code execution in the Amazon Braket Python SDK (versions 1.10.0 up to but not including 1.117.0) lets a remote authenticated actor with S3 write access to a Braket job output bucket run code on any machine that later processes those job results. The SDK reads the untrusted dataFormat field from results.json and, when it is set to pickled_v4, feeds attacker-controlled data into pickle.loads(), executing code with the victim SDK user's permissions. There is no public exploit identified at time of analysis, EPSS is low (0.32%), and CISA SSVC rates exploitation as none, but the technical impact is total.
Constraint extension stripping in the golang.org/x/crypto SSH agent client (versions prior to 0.52.0) allows remote SSH hosts to use forwarded keys without the destination restrictions the user intended. When clients added keys to a remote agent, extensions such as restrict-destination-v00@openssh.com were silently dropped during serialization, effectively converting scoped keys into unrestricted ones on downstream hosts. No public exploit identified at time of analysis and EPSS is very low (0.02%), but SSVC rates technical impact as total and automatable.
Remote code execution in Concrete CMS versions 5.0 through 9.5.0 allows a high-privileged administrator to bypass the platform's `_fromCIF` deserialization guard by submitting malicious payloads through the REST API instead of standard form POST requests. The flaw resides in the ExpressEntryList block controller (CWE-502) and stores a serialized PHP gadget in the `filterFields` database column, which is unmarshalled when another administrator subsequently views or edits the block, leading to full server takeover. No public exploit identified at time of analysis, and the issue is not present in CISA KEV.
Insecure deserialization in Apache Fory's PyFory (Python) library allows remote attackers to bypass DeserializationPolicy validation hooks via the ReduceSerializer, letting untrusted classes, functions, or module attributes be restored despite policy restrictions. All PyFory releases before 1.0.0 are affected when running Python-native mode with strict mode disabled, enabling attacker-controlled data to instantiate unsafe objects and achieve code execution. There is no public exploit identified at time of analysis and EPSS probability is very low (0.04%), but CVSS is 9.8 and SSVC rates technical impact as total with automatable exploitation.
Arbitrary code execution in NVIDIA BioNemo Framework on Linux allows a local attacker to abuse unsafe deserialization of untrusted data (CWE-502), leading to code execution, denial of service, information disclosure, and data tampering. The CVSS 7.8 vector indicates local attack vector with required user interaction, and no public exploit has been identified at time of analysis.
Unsafe deserialization in NVIDIA TensorRT-LLM's RPC testing component allows a local high-privileged attacker to trigger code execution, denial of service, data tampering, or information disclosure across a changed scope. The flaw is rated CVSS 7.5 despite local-only access and high attack complexity because successful exploitation crosses a security boundary (S:C) and yields full CIA impact. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Deserialization of untrusted data in NVIDIA TensorRT-LLM across all platforms allows a local, low-privileged attacker to achieve code execution, data tampering, and information disclosure by exploiting an unsafe serialized handle. The CVSS Changed Scope (S:C) indicates the impact can extend beyond the vulnerable component itself - notable given TensorRT-LLM's role as an inference serving library often integrated into multi-tenant or production AI infrastructure. No public exploit identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.
PHP Object Injection in the Boost plugin for WordPress (versions up to and including 2.0.3) allows unauthenticated remote attackers to inject arbitrary PHP objects via the STYXKEY-BOOST_USER_LOCATION cookie. The vulnerability stems from unsafe deserialization of attacker-controlled cookie data; while the plugin itself ships no usable POP (property-oriented programming) chain, exploitation becomes high-impact when any other installed plugin or theme provides one. No public exploit identified at time of analysis, and the issue is not currently listed in CISA KEV.
Remote code execution in Jaspersoft's JasperReports Library and Server (Community and Professional editions up to 7.0.6 / 10.0.0) arises from unsafe deserialization of untrusted Java objects (CWE-502), letting an authenticated attacker run arbitrary code on the host. The flaw carries full 'total' technical impact per SSVC, and its network-reachable, low-complexity vector makes it a strong patch priority despite requiring some privileges; no public exploit identified at time of analysis, and EPSS is modest at 0.40% (61st percentile).
Unauthenticated root-level remote code execution affects HestiaCP versions 1.9.0 through 1.9.4 when the optional web terminal feature is enabled, stemming from a session-handling format mismatch (CWE-502) between the PHP backend and the Node.js web terminal. Remote attackers can inject crafted HTTP header data that PHP writes into session storage but Node.js parses with naive string splitting, yielding arbitrary command execution as root; no public exploit identified at time of analysis, though VulnCheck has published a technical advisory and the upstream patch is publicly diffable.
Remote code execution in the TYPO3 'Content Element Selector' extension allows unauthenticated attackers to execute arbitrary PHP code by sending a crafted cookie that the extension feeds directly into PHP's unserialize(). The flaw (CWE-502, CVSS 4.0 score 9.2) is exploitable only on installations where a content element is configured with 'Persistent Mode: Static'. No public exploit identified at time of analysis, though the deserialization pattern is well-understood and typically rapid to weaponize.
Remote code execution in the TYPO3 Crawler extension occurs when the X-T3Crawler-Meta response header from a crawled URL is passed unchecked to PHP's unserialize(), enabling arbitrary PHP object injection. Exploitation requires a high-privileged administrator to configure a crawler-enabled page and a Scheduler task pointing at an attacker-controlled endpoint, so while impact is full RCE on the TYPO3 host, it is gated by an unusual combination of admin access, user interaction, and externally reachable malicious URLs. No public exploit identified at time of analysis and no CISA KEV listing.
Insecure deserialization in Significant-Gravitas AutoGPT platform versions 0.6.34 through 0.6.51 lets an attacker who can poison entries in the shared Redis cache achieve arbitrary command execution inside the backend container. The backend's read path invokes pickle.loads on cache bytes with no HMAC, signature, or schema gate, so any attacker-controlled value reaching that key becomes code on retrieval. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV; the vendor shipped a fix in autogpt-platform-beta-v0.6.52.
Remote code execution in APScheduler (all versions through 3.10.x and 4.0.0a5) is achievable when applications deserialize attacker-controlled data via the bundled JSONSerializer or CBORSerializer. The unmarshal_object routine dynamically imports modules and invokes __setstate__ on arbitrary classes, letting an attacker pivot an untrusted payload into code execution; publicly available exploit code exists, though EPSS remains low at 0.06% (19th percentile).
Remote code execution in FreePBX versions below 16.0.71 and 17.0.6 allows authenticated low-privileged users with backup access to execute arbitrary PHP code by uploading a malicious tar archive containing a crafted manifest file. The backup module passes attacker-controlled data directly to PHP's unserialize() without class restrictions, enabling PHP object injection that runs as the asterisk or www-data web server user. No public exploit identified at time of analysis, though the upstream fix commits are public on GitHub, making patch-diff exploitation feasible.
Unauthenticated remote code execution in SGLang (the LLM/multimodal generation serving runtime) affecting version 5.10 arises when the non-default `--enable-custom-logit-processor` flag is set, allowing attacker-supplied Python objects to be deserialized via `dill.loads()` and execute arbitrary code on the inference host. No CISA KEV listing exists and SSVC records exploitation as 'none', but a public technical write-up (antiproof.ai, 'Three RCEs in SGLang') details the flaw and SSVC marks it automatable with total technical impact. EPSS is modest at 0.32% (55th percentile), consistent with a serious-but-conditional (feature-gated) issue rather than mass exploitation.
Unauthenticated remote code execution affects SGLang, an LLM/multimodal inference-serving framework, at version 5.10, where the generation runtime scheduler's ZeroMQ ROUTER socket binds to 0.0.0.0 by default and deserializes incoming messages with pickle.loads(). Any attacker who can reach the exposed scheduler port can send a crafted pickle payload to execute arbitrary code on the host with full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis, though a vendor-independent technical writeup ('three RCEs in sglang') describes the flaw; EPSS is low (0.05%) and SSVC records no observed exploitation, but the issue is rated automatable with total technical impact.
Path traversal in SimpleSAMLphp's CAS server module allows unauthenticated remote attackers to read and deserialize arbitrary files outside the ticket directory via crafted ticket parameters. When using FileSystemTicketStore, attackers can inject '../' sequences into CAS validation endpoints to escape the configured directory, potentially deleting files that contain serialized PHP data compatible with array types. The vulnerability has a CVSS score of 8.6 with no public exploits identified at time of analysis.
Unsafe deserialization in LangSmith SDK's prompt pull methods allows remote attackers to execute server-side request forgery (SSRF) and redirect LLM traffic to attacker-controlled infrastructure when applications pull public prompts from LangSmith Hub. The SDK deserializes untrusted prompt manifests containing serialized LangChain objects with attacker-controlled constructor arguments, including malicious base_url configurations, custom headers, and secret references. Exploitation requires user interaction (developers must call pull_prompt with a malicious owner/name identifier), but no authentication is required to publish malicious prompts to the public Hub. Vendor-released patches in Python >= 0.8.0 and JS/TS >= 0.6.0 now block public prompt pulling by default, requiring explicit opt-in via dangerously_pull_public_prompt flag. EPSS data not available; no CISA KEV listing or public exploit identified at time of analysis.
Remote code execution in F5 BIG-IP and BIG-IQ Configuration utility allows authenticated attackers with low privileges to execute arbitrary code with high impact to confidentiality, integrity, and availability. The vulnerability stems from unsafe deserialization (CWE-502) in the management interface, exploitable over the network with low attack complexity and no user interaction required. Vendor-released patch available per F5 advisory K000156761. No public exploit identified at time of analysis, with CVSS 8.8 indicating critical severity for environments where attackers have valid low-privilege credentials to the Configuration utility.
PHP Object Injection vulnerability in coreActivity activity logging plugin through version 3.0 allows remote attackers to trigger persistent Denial of Service blocking administrator access to log pages. Unauthenticated attackers inject crafted PHP serialized payloads via User-Agent headers during any logged event (e.g., failed login). When administrators view the Logs page, the plugin deserializes untrusted data and passes it to DeviceDetector::setUserAgent(), causing Fatal TypeError. Vendor-released patch version 3.1 available (released May 6, 2026). EPSS exploitation probability not available; no CISA KEV listing at time of analysis. CVSS 8.1 reflects high complexity attack requiring precise payload crafting despite no authentication requirement.
Arbitrary code execution in Adobe Connect (versions 2025.9.15, 2025.8.157 and earlier) stems from insecure deserialization of untrusted data (CWE-502) and runs in the context of the current user. Exploitation requires the victim to visit a maliciously crafted URL or interact with a compromised web page, so it is user-interaction gated rather than fully automatic. There is no public exploit identified at time of analysis and it is not on the CISA KEV list; EPSS is modest at 1.50% (81st percentile), consistent with SSVC scoring exploitation as 'none' despite a 'total' technical impact.
Remote code execution in Microsoft SharePoint (Enterprise Server 2016, Server 2019, and Subscription Edition) allows an authenticated attacker to run arbitrary code on the server by submitting maliciously crafted serialized data (CWE-502). An authorized user holding only low-level site privileges can escalate to full server compromise over the network with no user interaction. No public exploit identified at time of analysis, and CISA SSVC records exploitation status as 'none'; EPSS sits at 0.50% (66th percentile), indicating modest near-term exploitation probability despite the high CVSS 8.8 score.
Remote code execution in Microsoft SharePoint Server (Enterprise Server 2016, Server 2019, and Subscription Edition) allows an authenticated attacker (PR:L) to run arbitrary code over the network by submitting maliciously crafted serialized data that the server deserializes without validation. Microsoft has released a patch and no public exploit identified at time of analysis; EPSS is modest at 0.50% (66th percentile) and CISA SSVC rates exploitation as 'none' but technical impact as 'total'. The bug follows the well-known SharePoint deserialization RCE pattern (CWE-502), making it a high-value target for post-authentication lateral movement and full server compromise.
Remote code execution in Microsoft SharePoint Server (2016, 2019, and Subscription Edition) allows an authenticated attacker to run arbitrary code across the network by submitting maliciously crafted serialized data (CWE-502). Any user holding low-privilege authenticated access to the SharePoint web application can achieve total compromise of the server (C:H/I:H/A:H). There is no public exploit identified at time of analysis, and the EPSS probability is modest at 0.50% (66th percentile), but the impact is total and a vendor patch is already available.
Remote code execution in Microsoft SharePoint Server (2016, 2019, and Subscription Edition) allows an authenticated attacker with low-level site privileges to run arbitrary code across the network by submitting maliciously crafted serialized data (CWE-502). Microsoft has released a patch; there is no public exploit identified at time of analysis, and the EPSS score is low (0.31%, 55th percentile), with CISA's SSVC framework rating exploitation status as 'none' but technical impact as 'total'. The combination of authenticated-but-low privilege access and full compromise of confidentiality, integrity, and availability makes this a meaningful escalation-to-RCE risk in enterprise collaboration environments.
Remote code execution in Microsoft SharePoint (Enterprise Server 2016, Server 2019, and Server Subscription Edition) allows an authenticated attacker to run arbitrary code over the network by supplying maliciously crafted serialized data (CWE-502). Any user holding valid low-privilege credentials on the SharePoint farm can achieve total compromise of confidentiality, integrity, and availability. There is no public exploit identified at time of analysis, and CISA SSVC records exploitation status as none; EPSS is a modest 0.50% (66th percentile).
Remote code execution in Snorkel machine learning library (≤v0.10.0) occurs when users load untrusted model files via MultitaskClassifier.load(). The vulnerability exploits insecure Python object deserialization through torch.load(), allowing attackers to embed malicious code in model weight files that executes upon loading. EPSS score of 0.06% (19th percentile) suggests low observed exploitation probability in the wild, though SSVC framework indicates total technical impact once exploited. No public exploit code or active exploitation confirmed at time of analysis, but exploitation requires only that a data scientist or ML engineer load a malicious .pkl model file.
Remote code execution in Adversarial Robustness Toolbox (ART) through version 1.20.1 allows unauthenticated network attackers to execute arbitrary Python code by uploading malicious PyTorch model files to pipeline-accessible object storage locations. The vulnerability stems from unsafe use of torch.load() without the weights_only=True parameter in the Kubeflow component's model loading process, enabling Pickle deserialization of arbitrary objects. With CVSS 9.8 (AV:N/AC:L/PR:N/UI:N) but only 0.06% EPSS exploitation probability (19th percentile), this represents a critical-severity issue with low observed real-world targeting, likely due to the specialized nature of ML robustness evaluation deployments. No active exploitation confirmed (not in CISA KEV) and no public exploit code identified at time of analysis.
Remote code execution in Mamba language model framework (through version 2.2.6) allows unauthenticated attackers to execute arbitrary Python code by publishing malicious models on HuggingFace Hub. When victims call MambaLMHeadModel.from_pretrained() on a weaponized model repository, insecure pickle deserialization executes attacker-controlled code in the context of the victim's process. Despite the critical CVSS 9.8 score and network attack vector requiring no authentication, EPSS probability remains extremely low (0.02%, 5th percentile), suggesting limited real-world exploitation to date. No CISA KEV listing or public POC identified at time of analysis.
Remote code execution in Ludwig framework ≤0.10.4 allows unauthenticated network attackers to execute arbitrary code by supplying a malicious PyTorch model file to the ludwig serve endpoint. The vulnerability stems from unsafe deserialization in the model loading component, which uses torch.load() without the weights_only=True safety parameter. With CVSS 9.8 (critical network vector, no authentication required) but only 0.02% EPSS, this represents a high-severity issue in vulnerable deployments, though widespread exploitation has not been observed. No CISA KEV listing or public POC identified at time of analysis.
Remote code execution in Optimate's neural_magic_training.py script allows authenticated attackers to execute arbitrary code via malicious PyTorch model files. The vulnerability stems from unsafe deserialization when loading model state dictionaries without PyTorch's weights_only=True security flag, enabling pickle-based arbitrary object execution. With an EPSS score of 0.06% and no confirmed exploitation, this represents a moderate risk primarily in environments where users can upload or specify model files.
Arbitrary code execution occurs in PyTorch Lightning 2.6.0 and earlier when loading malicious checkpoint files. The LightningModule.load_from_checkpoint() method deserializes untrusted Pickle data without security restrictions, allowing attackers to execute arbitrary Python code when victims open crafted .ckpt files. EPSS score of 0.06% (19th percentile) indicates low observed exploitation probability, and no public exploit code or CISA KEV listing exists at time of analysis. Attack requires local access and user interaction (opening a malicious checkpoint), limiting remote attack scenarios to social engineering or supply chain compromise.
Arbitrary code execution in imgaug library (versions through 0.4.0) occurs when the BackgroundAugmenter class deserializes malicious pickle payloads without validation in its multiprocessing worker method. Attackers who can influence queue data-through compromised shared queues, malicious input scripts, or social engineering-can achieve remote or local code execution depending on deployment context. CVSS 9.8 critical severity reflects network-based exploitation without authentication, though EPSS probability is low (0.02%, 6th percentile), indicating limited observed exploitation activity. No CISA KEV listing or public exploit code identified at time of analysis.
Insecure deserialization in Optimate's neural_magic_training.py script enables remote code execution when loading PyTorch model files. The _load_model() function uses torch.load() without the weights_only=True security parameter, allowing attackers with low privileges to execute arbitrary Python code by providing malicious .pt or .pth files via the --model command-line argument. EPSS indicates low exploitation probability at 0.06% with no active exploitation confirmed.
Arbitrary code execution in Snorkel machine learning library (≤v0.10.0) occurs when users load malicious model checkpoint files through the Trainer.load() method. The vulnerability stems from unsafe PyTorch deserialization that processes untrusted Pickle objects without the weights_only security parameter. Attackers can embed malicious Python code in model files distributed through repositories, shared datasets, or social engineering campaigns. Despite the 8.8 CVSS score indicating critical severity, EPSS scoring at 0.06% (19th percentile) suggests very low real-world exploitation probability, and no active exploitation or public proof-of-concept has been identified at time of analysis.
Arbitrary code execution in Snorkel library (Python) through version 0.10.0 enables remote attackers to execute code by supplying malicious pickle files to the BaseLabeler.load() method. The vulnerability stems from unsafe deserialization using pickle.load() without input validation, allowing attackers to craft serialized objects that execute arbitrary commands during deserialization. With EPSS at 6th percentile, exploitation probability remains relatively low despite the critical CVSS score, and no active exploitation (KEV) or public proof-of-concept has been identified at time of analysis.
Arbitrary code execution via torch-checkpoint-shrink.py script in ml-engineering project allows remote attackers to execute malicious Python code by providing crafted PyTorch checkpoint files. The vulnerability stems from insecure deserialization where torch.load() processes .pt files without the weights_only=True safeguard, enabling pickle-based arbitrary object instantiation. Despite a critical CVSS 9.8 score, EPSS probability is low (0.06%, 19th percentile) and no public exploit or active exploitation is confirmed, suggesting limited real-world targeting to date. SSVC assessment indicates total technical impact with automatable exploitation potential, making this a priority for organizations using ml-engineering scripts in production environments.
Remote code execution in Horovod distributed training framework (versions through 0.28.1) allows unauthenticated network attackers to execute arbitrary code on worker nodes by injecting malicious pickle payloads into the KVStore HTTP server. The vulnerability combines unauthenticated write access to the KVStore coordination server with unsafe deserialization using cloudpickle.loads(), enabling trivial exploitation against any reachable Horovod cluster. EPSS score of 0.12% (31st percentile) suggests low widespread exploitation probability despite critical CVSS 9.8 rating, and no active exploitation confirmed (not in CISA KEV). Public exploit development is highly feasible given the straightforward attack path and publicly documented details.
Arbitrary code execution in Ludwig framework ≤0.10.4 occurs when attackers supply malicious pickle files to the predict() method, which deserializes untrusted data without validation using pandas.read_pickle(). Remote unauthenticated attackers can achieve full system compromise by exploiting the automatic file format detection mechanism that processes .pkl files through Python's unsafe pickle module. EPSS score of 0.06% (19th percentile) suggests low current exploitation likelihood despite the critical CVSS 9.8 rating, though no public exploit code or active exploitation has been identified at time of analysis.
Remote code execution in CosyVoice (FunAudioLLM's open-source text-to-speech toolkit) up to commit 6e01309 allows an attacker to run arbitrary Python on a victim's host when the victim loads an attacker-supplied model directory. The flaw stems from calling torch.load() without weights_only=True, so malicious pickle payloads embedded in .pt model files execute during model loading via the web interface. There is no public exploit identified at time of analysis and EPSS is very low (0.05%, 17th percentile), but SSVC rates the technical impact as total.
Unsafe Python pickle deserialization in pgAdmin 4 FileBackedSessionManager allows authenticated local users with session-directory write access to execute arbitrary code as the pgAdmin process. The vulnerability arises from deserializing session files before validating their HMAC signature, enabling payload injection through crafted pickle objects. Attackers require both valid authentication and filesystem write permission to the sessions directory-achievable through misconfiguration or chaining with a separate path-traversal vulnerability. EPSS exploitation probability and KEV status not provided; no public exploit code identified at time of analysis. PostgreSQL maintainers confirmed the flaw and patched it in version 9.15 by implementing pre-deserialization HMAC validation.
Arbitrary code execution in CosyVoice (FunAudioLLM's multilingual text-to-speech toolkit) through commit 6e01309 allows an attacker to run code on a victim's machine via a malicious PyTorch .pt file. The vulnerability lives in the make_parquet_list.py data-preparation tool, which calls torch.load() without weights_only=True, so any .pt file it ingests can carry a malicious pickle payload that executes when the victim processes an attacker-supplied data directory. Reported by MITRE with a low EPSS (0.02%, 5th percentile) and no public exploit identified at time of analysis; this is a poisoned-input/supply-chain style flaw rather than a remotely reachable network service.
Arbitrary code execution in CosyVoice (FunAudioLLM's open-source multilingual text-to-speech toolkit) arises because its average_model.py utility calls PyTorch's torch.load() on epoch_*.pt checkpoint files without weights_only=True, allowing pickle-based deserialization of attacker-controlled objects. Any user who runs the model-averaging tool against a directory containing a malicious checkpoint executes attacker code on their machine. There is no public exploit identified at time of analysis and EPSS is very low (0.02%), but the CWE-502 pattern is trivially weaponizable and SSVC marks it automatable.
Arbitrary code execution in the Dao-AILab flash-attention training framework (all revisions up to and including commit e724e2588cbe754beb97cf7c011b5e7e34119e62) arises because its checkpoint-loading paths call PyTorch's torch.load() without weights_only=True, permitting pickle-based deserialization of attacker-controlled objects. Any user who warmstarts or evaluates a model from an untrusted checkpoint file triggers code execution on their host. No public exploit is identified at time of analysis, EPSS is negligible (0.02%), and SSVC records exploitation as 'none' - this is a latent supply-chain/ML-artifact risk rather than an actively exploited one.
Arbitrary code execution in CosyVoice's gRPC server (through commit 6e01309e) occurs because the speech-synthesis model is loaded via torch.load() without weights_only=True, deserializing untrusted pickle data. Any operator who starts the gRPC server against an attacker-supplied model directory executes embedded Python code during initialization. No public exploit has been identified and it is not in CISA KEV; EPSS is negligible at 0.02% (5th percentile), consistent with a file-delivery attack rather than mass remote exploitation.
Unsafe deserialization in LangChain (langchain-core >= 1.0.0a1, <= 1.3.2 and <= 0.3.84) lets attackers who can place structured input into preserved run data revive arbitrary trusted LangChain-serializable objects via legacy runtime paths that call load() with allowed_objects="all". Affected surfaces include RunnableWithMessageHistory, astream_log(), and astream_events(version="v1"); a companion _is_lc_secret marker bypass lets crafted constructor dictionaries survive dumps()->loads() round-trips. Impact ranges from persistent chat-history poisoning and downstream prompt injection to possible credential disclosure or SSRF if a revived object touches environment secrets or network clients during initialization; no public exploit is identified at time of analysis and EPSS is negligible (0.01%).
Remote code execution in SEPPmail Secure Email Gateway via insecure deserialization allows unauthenticated attackers to execute arbitrary code through the GINA UI interface. Versions prior to 15.0.4 deserialize untrusted data without validation, enabling attackers to send crafted serialized objects that execute upon processing. CVSS 9.2 reflects network-accessible attack with low complexity requiring only present attack conditions, though no active exploitation (KEV) or public POC has been identified at time of analysis.
PHP object injection in User Frontend plugin for WordPress versions up to 4.3.1 allows authenticated attackers with Subscriber-level access or above to achieve remote code execution via unsafe deserialization of the wpuf_files parameter during form submission. The vulnerability chains input validation failures during form processing with unconditional use of maybe_unserialize() when rendering post content, enabling attackers to inject malicious PHP objects that can execute arbitrary code, delete files, or trigger other attacks through available Property-Oriented Programming (POP) chains. Wordfence disclosed detailed code references showing the vulnerable data flow across multiple plugin files including wpuf-functions.php, FieldableTrait.php, and Frontend_Form_Ajax.php, with both trunk and version 4.2.10 code paths exhibiting the flaw.
LINQPad before 5.52.01 Pro edition is vulnerable to Unsafe Deserialization in LINQPad.AutoRefManager::PopulateFromCache(), leading to code execution. Rated high severity (CVSS 7.3), this vulnerability is low attack complexity. Public exploit code available and no vendor patch available.
Denial of service in Nerdbank.MessagePack (NuGet, versions < 1.1.62) allows a remote unauthenticated attacker to crash any .NET process that deserializes untrusted MessagePack into a type graph containing a DateTime. A tiny crafted payload declares an oversized timestamp extension length, which is propagated unvalidated into a stackalloc on the streaming reader's slow path, producing an uncatchable StackOverflowException that terminates the process. No public exploit identified at time of analysis and EPSS is very low (0.04%), but the attack is trivial and a vendor patch (1.1.62) is available.
Remote denial of service in Apache OpenNLP versions before 2.5.9 and 3.0.0-M3 allows unauthenticated attackers to crash JVM processes by uploading malicious .bin model files that trigger OutOfMemoryError through unbounded array allocation. Exploitation requires no authentication (AV:N/AC:L/PR:N) and affects any code path deserializing binary model files from untrusted sources. EPSS score of 0.02% (5th percentile) suggests low widespread exploitation risk, and no active exploitation or public POC has been identified at time of analysis. Vendor-released patches are available with default safeguards limiting count fields to 10 million entries.
Unauthenticated PHP object injection in Profile Builder Pro for WordPress allows remote attackers to execute arbitrary code by deserializing malicious objects through an unprotected AJAX endpoint. The vulnerability affects all versions through 3.14.5 and stems from unsafe deserialization of attacker-controlled POST data in the wppb_request_users_pins_action_callback() handler, which was registered for both authenticated and unauthenticated users without nonce verification. With CVSS 8.1 and AC:H complexity, exploitation requires chaining with a POP gadget chain, though EPSS data and KEV status are not available to confirm active exploitation.
Remote code execution in Apache MINA 2.1.0-2.1.11 and 2.2.0-2.2.6 allows unauthenticated attackers to execute arbitrary code via unsafe deserialization. The fix for prior CVE-2024-52046 was incomplete-the classname allowlist protecting IoBuffer.getObject() was applied too late, allowing malicious static initializers to execute before filtering. Confirmed actively exploited (CISA KEV). EPSS exploitation probability not provided, but the network-accessible, unauthenticated attack vector (CVSS:3.1/AV:N/AC:L/PR:N/UI:N) combined with KEV status indicates immediate patching is critical for applications calling IoBuffer.getObject().
Remote unauthenticated code execution in Apache MINA 2.1.0-2.1.11 and 2.2.0-2.2.6 allows attackers to bypass class allowlist protections via unsafe deserialization. The vulnerability exists because the fix for CVE-2026-41635 was not backported to the 2.1.X and 2.2.X branches, leaving AbstractIoBuffer.resolveClass() susceptible to arbitrary class instantiation when applications call IoBuffer.getObject(). Only applications actively using MINA's deserialization features are affected. EPSS data not available; no KEV listing or public POC identified at time of analysis.
Unsafe deserialization in Zurich Instruments LabOne Q enables arbitrary code execution when users load malicious experiment files. The import_cls mechanism accepts unvalidated class names from serialized data, allowing attackers to instantiate arbitrary Python classes with controlled constructor arguments. Exploitation requires user interaction to open a crafted file, making this a credible vector for supply chain attacks via shared experiment configurations or support tickets. CVSS 8.4 reflects local attack vector with user interaction requirement. No confirmed active exploitation or public POC at time of analysis.
Remote code execution in MixPHP Framework 2.x through 2.2.17 allows unauthenticated network attackers to execute arbitrary code via unsafe deserialization. The FileHandler class processes session and cache data using PHP's unserialize() on filesystem-sourced content without validation, enabling object injection attacks. CVSS 9.8 critical severity with network attack vector and no privileges required. SSVC assessment confirms automatable exploitation with total technical impact. No active exploitation confirmed at time of analysis (not in CISA KEV), but publicly available proof-of-concept exists (GitHub gist reference).
Client-side remote code execution affects MixPHP Framework 2.x through 2.2.17 when sync-invoke clients connect to attacker-controlled servers. The vulnerability enables malicious servers to execute arbitrary code on connecting clients through unsafe deserialization of server responses (CWE-502). EPSS data unavailable, but SSVC indicates no confirmed exploitation and non-automatable attack complexity aligns with CVSS AC:H rating. Primary risk exists in scenarios where MixPHP clients connect to untrusted external services or where server infrastructure could be compromised.
Remote unauthenticated code execution in MixPHP Framework 2.x through 2.2.17 allows attackers to execute arbitrary PHP code by injecting malicious serialized objects into Redis-backed session or cache storage. The framework's RedisHandler directly deserializes untrusted data from Redis using PHP's unserialize() function without validation. CVSS 9.8 with network vector, low complexity, and no privileges required. EPSS and KEV status not provided; SSVC framework marks this as automatable with total technical impact, indicating high exploitability despite no confirmed active exploitation at time of analysis.
Arbitrary code execution in MixPHP Framework 2.x through 2.2.17 allows local attackers to execute malicious PHP closures via unauthenticated TCP connections to the sync-invoke server. The vulnerability stems from unsafe deserialization of untrusted data on localhost-bound port 127.0.0.1, where Server.php directly passes socket data to Opis\Closure\unserialize() and executes the result without authentication or signature verification. Exploitation requires local network access or SSRF capability against the application server. No public exploit code identified at time of analysis, but the attack mechanism is straightforward for attackers with PHP deserialization knowledge.
Remote code execution in Hyperledger fabric-sdk-java (all versions 1.0.0 through 2.2.26) allows unauthenticated attackers to execute arbitrary commands via malicious serialized Java objects. The deprecated SDK's Channel.java class deserializes untrusted byte arrays without input filtering in readObject() and deSerializeChannel() methods, enabling classic Java gadget chain exploitation. Publicly available exploit code exists (ysoserial toolkit), and exploitation requires only that an application accept Channel serialization data from attacker-controlled sources such as compromised files, external APIs, or injected parameters. EPSS data unavailable; not listed in CISA KEV. Vendor has published GHSA advisory but provides no patch-remediation requires migration to the replacement fabric-gateway SDK.
Server-side request forgery and potential remote code execution affect PhpOffice PhpSpreadsheet when an application passes an attacker-controlled filename to IOFactory::load or any Reader. Because the File::assertFile helper validates paths with is_file(), which is PHP stream-wrapper aware, an attacker can supply phar://, ftp://, or ssh2.sftp:// paths to force outbound connections (SSRF) or trigger phar metadata deserialization (CWE-502) leading to code execution if a usable POP gadget exists. Publicly available exploit code exists (PoC in the GitHub advisory); it is not in CISA KEV and EPSS is low (0.10%), indicating no observed widespread exploitation yet.
Remote code execution in NVIDIA FLARE SDK allows authenticated attackers to execute arbitrary code by sending maliciously crafted FOBS-encoded messages that exploit unsafe deserialization in the FOBS component. The vulnerability affects federated learning deployments where NVIDIA FLARE SDK processes messages from low-privileged authenticated users, enabling complete system compromise with high impact to confidentiality, integrity, and availability. No active exploitation confirmed (not in CISA KEV) and public exploit status unknown at time of analysis.
Unsafe Java deserialization in Apache Camel's camel-consul component (ConsulRegistry / ConsulRegistryUtils.deserialize) lets an attacker who can write to the backing Consul KV store achieve arbitrary code execution inside the Camel process. Any deployment using a Consul-backed Camel registry on versions 3.0.0 up to 4.14.6 or 4.15.0 up to 4.18.1 is affected. There is no public exploit identified at time of analysis, EPSS is low (0.08%), and this is a missed instance of the same deserialization class fixed in CVE-2024-22369, CVE-2024-23114 and CVE-2026-25747.
Message header injection in Apache Camel's camel-mail component (3.0.0 before 4.14.6 and 4.15.0 before 4.18.1) lets an attacker who can email a monitored mailbox smuggle Camel-prefixed MIME headers into the Exchange. Because MailHeaderFilterStrategy filters only the outbound direction and never sets an inbound filter, inbound Camel headers reach downstream components such as camel-bean, camel-exec, or camel-sql where they can alter route behavior, potentially reaching command or query execution. There is no public exploit identified at time of analysis and EPSS is very low (0.02%), but the vendor rates it CVSS 9.4 and SSVC marks it automatable.
Unsafe Java deserialization in Apache Camel's camel-infinispan component allows arbitrary code execution when the ProtoStream-based remote aggregation repository reads objects from an Infinispan cache using java.io.ObjectInputStream with no ObjectInputFilter applied. Any attacker able to write to the backing Infinispan cache can plant a malicious serialized gadget that executes in the application context during routine get/recover operations. Publicly available exploit code exists, though EPSS is low (0.08%) and there is no evidence of active exploitation.
Local code execution in NVIDIA NVTabular allows an authenticated low-privileged user to abuse improper deserialization of untrusted data to run arbitrary code, tamper with data, and disclose sensitive information. The CVSS 3.1 base score is 7.8 (AV:L/AC:L/PR:L/UI:N) reflecting a local attack vector with low complexity and low privileges; no public exploit identified at time of analysis and the issue is not on the CISA KEV list.
PHP object injection in the Elated-Themes Askka WordPress theme through version 1.3.1 allows remote attackers to deserialize untrusted data, potentially leading to arbitrary code execution, file manipulation, or full site compromise depending on available gadget chains. The CVSS score of 8.1 reflects high impact across confidentiality, integrity, and availability, though high attack complexity (AC:H) tempers immediate exploitability. No public exploit identified at time of analysis.
PHP object injection in the Elated-Themes Töbel WordPress theme (versions up to and including 1.8.1) allows remote attackers to trigger unsafe deserialization of attacker-controlled data, potentially leading to arbitrary code execution, file manipulation, or data tampering depending on available POP gadgets. Rated CVSS 8.1 (High) with no public exploit identified at time of analysis and no CISA KEV listing, though the network attack vector and lack of authentication requirement make it a meaningful risk to any WordPress site running the theme.
Object injection in the Elated-Themes Aperitif WordPress theme through version 1.6 allows remote attackers to trigger PHP deserialization of attacker-controlled data, potentially leading to code execution, file manipulation, or full site compromise when a suitable gadget chain is present. CVSS 8.1 reflects high impact across confidentiality, integrity, and availability, though attack complexity is rated High. No public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Remote code execution in Microsoft SharePoint Server (2016 Enterprise, 2019, and Subscription Edition) allows an authenticated attacker to execute arbitrary code on the server by submitting crafted serialized data that triggers unsafe deserialization. The CVSS 8.0 vector requires low privileges and user interaction, and no public exploit is identified at time of analysis. The flaw is significant because SharePoint servers typically run with high privileges inside enterprise environments and frequently host sensitive collaboration data.
Remote code execution in IBM WebSphere Application Server 9.0 and 8.5 allows authenticated attackers to abuse unsafe Java deserialization in the SAML Web Single Sign-On component to run arbitrary code via a crafted HTTP request combined with a gadget chain. The flaw carries a CVSS 8.5 with scope change, and while no public exploit has been identified at time of analysis, deserialization gadget chains for WebSphere are historically well-researched. IBM has released a patch via support advisory node/7274733.
Remote code execution in IBM WebSphere Application Server 9.0 and 8.5 arises from unsafe deserialization of untrusted data processed by JAX-WS endpoints that use WS-Security. Unauthenticated remote attackers who can reach a SOAP/JAX-WS endpoint may craft malicious serialized payloads to execute arbitrary code in the WebSphere server context. No public exploit identified at time of analysis, but the high CVSS (9.0) and scope-changed impact mean any exposed JAX-WS service is a meaningful target.
Remote code execution in AMD's AI Tensor Engine for ROCm (AITER) through version 0.1.14 allows unauthenticated network attackers to run arbitrary code on every inference worker in a distributed cluster by sending a malicious pickle payload to the ZMQ SUB socket consumed by MessageQueue.recv() in shm_broadcast.py. The vulnerability stems from unauthenticated, unvalidated pickle deserialization with no HMAC or format checks; no public exploit identified at time of analysis, but VulnCheck has published an advisory and AMD has merged an upstream fix.
Unauthenticated remote code execution in Dassault Systèmes Teamwork Cloud (No Magic Release 2022x-2026x) and Magic Collaboration Studio (CATIA Magic Release 2022x-2026x) arises from unsafe deserialization of attacker-controlled data. The CVSS 9.8 vector indicates a network-reachable attack with no privileges or user interaction, yielding full confidentiality, integrity, and availability impact, though no public exploit identified at time of analysis and EPSS data was not provided.
Arbitrary code execution in ESA AnomalyMatch before 1.3.1 allows local attackers with low privileges to run code under the application's process by planting a malicious PyTorch checkpoint into a session directory, which is loaded via torch.load() with weights_only=False. No public exploit is identified at time of analysis, but the upstream fix (PR #9) and a third-party advisory (imlabs.info) confirm the unsafe-deserialization root cause and the migration to safetensors.
Arbitrary Python module import in Apache Airflow versions prior to 3.2.2 occurs when the scheduler deserializes custom DeadlineReference objects, because the prior implementation called import_string() directly on an attacker-controllable __class_path field. Rated CVSS 7.3 with low confidentiality/integrity/availability impact, this issue has no public exploit identified at time of analysis and EPSS estimates exploitation probability at 0.02% (6th percentile).
Authenticated remote code execution in Apache Airflow 3.2.0 through 3.2.1 allows users with permission to update XCom entries to achieve code execution by submitting reserved deserialization metadata keys (e.g. __classname__, __type, __data__, __var) to the PATCH XCom endpoint. The XComUpdateBody datamodel omitted the FORBIDDEN_XCOM_KEYS validator that XComCreateBody enforced, letting attackers smuggle a malicious typed payload that is later deserialized into an arbitrary Python class. No public exploit identified at time of analysis and EPSS risk is negligible (0.02%), but a vendor fix has shipped and the root cause is a classic CWE-502 untrusted deserialization.
Remote code execution in manga-image-translator's share.py API server allows unauthenticated attackers to achieve full container compromise via unsafe pickle deserialization. The /execute/{method_name} and /simple_execute/{method_name} endpoints deserialize attacker-controlled request bodies with pickle.loads(), enabling arbitrary code execution in the server process. Publicly available exploit code exists, but the EPSS score (0.36%) indicates low current exploitation probability.
Remote code execution in SMSGate sms-core versions 2.1.13.6 and earlier allows remote attackers to execute arbitrary code by sending crafted input to the Cmpp7FDeliverRequestMessageCodec.java component, which handles CMPP protocol message decoding. The CVSS 7.3 (AV:N/AC:L/PR:N/UI:N) vector indicates network-reachable, unauthenticated exploitation with low complexity, though EPSS scores this at only 0.06% (18th percentile) and there is no public exploit identified at time of analysis. SSVC indicates exploitation status is 'none' but the issue is automatable with partial technical impact across CIA.
Arbitrary file deletion in the WP Contact Form 7 DB Handler WordPress plugin (versions up to and including 3.0) can be achieved by chaining CSRF, UNION-based SQL injection, and PHP object deserialization. A remote unauthenticated attacker who lures a logged-in administrator to a malicious page can delete arbitrary server files, including wp-config.php, which typically forces the site into a re-installation state and enables full site takeover. No public exploit identified at time of analysis, though Wordfence's detailed write-up effectively documents the exploit chain.
Unauthenticated PHP object deserialization in Symfony's Monolog Bridge affects the development-time `server:log` console command, which by default binds its TCP log listener to 0.0.0.0:9911 and passes every received frame through `unserialize(base64_decode(...))` with no allowed_classes allowlist, authentication, or integrity check. Any host that can reach port 9911 on a machine running `server:log` can crash the listener (unauthenticated DoS) or trigger PHP object injection whose magic-method side effects may reach remote code execution when a usable gadget chain exists in the target's autoload set. No public exploit identified at time of analysis; EPSS is low (0.99%, 77th percentile) and the flaw is not in CISA KEV, consistent with a dev-only tool rather than a production-facing service.
Remote code execution in RELATE LMS (the inducer/relate web courseware platform) stems from its Celery task queue being configured to accept and unpickle untrusted messages (CELERY_ACCEPT_CONTENT included "pickle"). Because the code-execution sandbox lacks network isolation, an authenticated student can reach the message broker and deliver a malicious pickle payload that the worker deserializes, yielding arbitrary command execution on the host. No public exploit identified at time of analysis; the issue is corrected in commit d66ba5659b459bf1ba56b7109b5f9ecf197cbefb.
PHP object injection in Pimcore (packages pimcore/pimcore and admin-ui-classic-bundle) up to and including version 12.3.6 arises from six code paths calling unserialize() without the allowed_classes restriction on values read from database columns and filesystem files. An attacker who can already write to one of those sources - for example through SQL injection into the tmp_store, sites, or custom_layouts tables, or a file write to the WebDAV delete log - can plant a serialized PHP gadget chain that executes arbitrary code with web-server privileges once the data is deserialized. No public exploit identified at time of analysis (the vendor advisory documents only a conceptual PoC procedure), the CVE is not in CISA KEV, and EPSS is not provided; the issue is fixed in 12.3.7 and rated CVSS 8.0, with the High attack-complexity reflecting its dependence on a separate write primitive and a working gadget chain.
SQL injection in Pimcore's admin-ui-classic-bundle (versions <= 2.3.5) allows an authenticated user holding only the translations-view permission to read arbitrary database contents by injecting into the translation grid's date filter. The user-controlled 'property' field of the filter JSON is interpolated directly into a UNIX_TIMESTAMP(DATE(FROM_UNIXTIME(...))) expression at the POST /admin/translation/translations endpoint, behind only a trivially bypassable str_replace('--','') filter. A working proof-of-concept and publicly available exploit code exist; the reporter notes it can be chained with an unsafe-unserialize flaw (GM-249) to reach remote code execution. No EPSS score or CISA KEV listing was supplied.
Insecure deserialization in NVIDIA Merlin Transformers4Rec on Linux allows a local attacker to achieve code execution, data tampering, and information disclosure by tricking a user into loading a malicious serialized object. The flaw affects all Main-branch commits prior to March 11, 2026, and currently has no public exploit identified at time of analysis, with a very low EPSS score (0.02%) reflecting limited real-world activity. CISA SSVC classifies exploitation as 'none' but technical impact as 'total', placing it firmly in the supply-chain/MLOps risk category rather than a mass-exploitation threat.
Remote code execution in Mirasvit Full Page Cache Warmer for Magento 2 before 1.11.12 allows unauthenticated attackers to execute arbitrary code by sending a crafted serialized PHP object in the CacheWarmer cookie. The flaw is confirmed actively exploited (CISA KEV) with publicly available exploit code, and successful exploitation chains Magento and dependency gadget chains via an unsafe call to unserialize(). Despite a low EPSS score (0.10%), KEV listing and CVSS 9.3 indicate this is a high-priority patch for any Magento 2 store running the module.
Remote code execution in HuggingFace Transformers prior to 5.3.0 allows attackers to achieve arbitrary code execution on a victim's machine by publishing a malicious model whose config.json sets the `_attn_implementation_internal` field to an attacker-controlled Hub repository. When the victim calls the standard `AutoModelForCausalLM.from_pretrained()` API, the library silently downloads and executes Python kernels from that repository with the victim's privileges, bypassing the `trust_remote_code` safety gate. No public exploit is identified at time of analysis (EPSS 0.03%, SSVC exploitation: none), but the technical impact is total and the attack uses the documented, default usage pattern.
Information disclosure in Microsoft Planetary Computer Pro (GeoCatalog) lets a remote, unauthenticated attacker read sensitive data by sending crafted serialized objects that the service deserializes without validation (CWE-502). The flaw carries a CVSS 3.1 score of 7.5 (confidentiality-only impact) and, per SSVC, is automatable but has no observed exploitation; there is no public exploit identified at time of analysis, and EPSS estimates a low 0.27% probability of exploitation in the next 30 days.
Authenticated remote code execution in Microsoft SharePoint (Enterprise Server 2016, Server 2019, and Subscription Edition) stems from unsafe deserialization of untrusted data (CWE-502), enabling an authorized attacker to run arbitrary code on the server over the network. CVSS 8.8 with low privileges required and no user interaction makes this attractive to post-authentication adversaries, though no public exploit identified at time of analysis and CVSS temporal data marks exploit code maturity as Unproven.
Arbitrary code execution in the Amazon Braket Python SDK (versions 1.10.0 up to but not including 1.117.0) lets a remote authenticated actor with S3 write access to a Braket job output bucket run code on any machine that later processes those job results. The SDK reads the untrusted dataFormat field from results.json and, when it is set to pickled_v4, feeds attacker-controlled data into pickle.loads(), executing code with the victim SDK user's permissions. There is no public exploit identified at time of analysis, EPSS is low (0.32%), and CISA SSVC rates exploitation as none, but the technical impact is total.
Constraint extension stripping in the golang.org/x/crypto SSH agent client (versions prior to 0.52.0) allows remote SSH hosts to use forwarded keys without the destination restrictions the user intended. When clients added keys to a remote agent, extensions such as restrict-destination-v00@openssh.com were silently dropped during serialization, effectively converting scoped keys into unrestricted ones on downstream hosts. No public exploit identified at time of analysis and EPSS is very low (0.02%), but SSVC rates technical impact as total and automatable.
Remote code execution in Concrete CMS versions 5.0 through 9.5.0 allows a high-privileged administrator to bypass the platform's `_fromCIF` deserialization guard by submitting malicious payloads through the REST API instead of standard form POST requests. The flaw resides in the ExpressEntryList block controller (CWE-502) and stores a serialized PHP gadget in the `filterFields` database column, which is unmarshalled when another administrator subsequently views or edits the block, leading to full server takeover. No public exploit identified at time of analysis, and the issue is not present in CISA KEV.
Insecure deserialization in Apache Fory's PyFory (Python) library allows remote attackers to bypass DeserializationPolicy validation hooks via the ReduceSerializer, letting untrusted classes, functions, or module attributes be restored despite policy restrictions. All PyFory releases before 1.0.0 are affected when running Python-native mode with strict mode disabled, enabling attacker-controlled data to instantiate unsafe objects and achieve code execution. There is no public exploit identified at time of analysis and EPSS probability is very low (0.04%), but CVSS is 9.8 and SSVC rates technical impact as total with automatable exploitation.
Arbitrary code execution in NVIDIA BioNemo Framework on Linux allows a local attacker to abuse unsafe deserialization of untrusted data (CWE-502), leading to code execution, denial of service, information disclosure, and data tampering. The CVSS 7.8 vector indicates local attack vector with required user interaction, and no public exploit has been identified at time of analysis.
Unsafe deserialization in NVIDIA TensorRT-LLM's RPC testing component allows a local high-privileged attacker to trigger code execution, denial of service, data tampering, or information disclosure across a changed scope. The flaw is rated CVSS 7.5 despite local-only access and high attack complexity because successful exploitation crosses a security boundary (S:C) and yields full CIA impact. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Deserialization of untrusted data in NVIDIA TensorRT-LLM across all platforms allows a local, low-privileged attacker to achieve code execution, data tampering, and information disclosure by exploiting an unsafe serialized handle. The CVSS Changed Scope (S:C) indicates the impact can extend beyond the vulnerable component itself - notable given TensorRT-LLM's role as an inference serving library often integrated into multi-tenant or production AI infrastructure. No public exploit identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.
PHP Object Injection in the Boost plugin for WordPress (versions up to and including 2.0.3) allows unauthenticated remote attackers to inject arbitrary PHP objects via the STYXKEY-BOOST_USER_LOCATION cookie. The vulnerability stems from unsafe deserialization of attacker-controlled cookie data; while the plugin itself ships no usable POP (property-oriented programming) chain, exploitation becomes high-impact when any other installed plugin or theme provides one. No public exploit identified at time of analysis, and the issue is not currently listed in CISA KEV.
Remote code execution in Jaspersoft's JasperReports Library and Server (Community and Professional editions up to 7.0.6 / 10.0.0) arises from unsafe deserialization of untrusted Java objects (CWE-502), letting an authenticated attacker run arbitrary code on the host. The flaw carries full 'total' technical impact per SSVC, and its network-reachable, low-complexity vector makes it a strong patch priority despite requiring some privileges; no public exploit identified at time of analysis, and EPSS is modest at 0.40% (61st percentile).
Unauthenticated root-level remote code execution affects HestiaCP versions 1.9.0 through 1.9.4 when the optional web terminal feature is enabled, stemming from a session-handling format mismatch (CWE-502) between the PHP backend and the Node.js web terminal. Remote attackers can inject crafted HTTP header data that PHP writes into session storage but Node.js parses with naive string splitting, yielding arbitrary command execution as root; no public exploit identified at time of analysis, though VulnCheck has published a technical advisory and the upstream patch is publicly diffable.
Remote code execution in the TYPO3 'Content Element Selector' extension allows unauthenticated attackers to execute arbitrary PHP code by sending a crafted cookie that the extension feeds directly into PHP's unserialize(). The flaw (CWE-502, CVSS 4.0 score 9.2) is exploitable only on installations where a content element is configured with 'Persistent Mode: Static'. No public exploit identified at time of analysis, though the deserialization pattern is well-understood and typically rapid to weaponize.
Remote code execution in the TYPO3 Crawler extension occurs when the X-T3Crawler-Meta response header from a crawled URL is passed unchecked to PHP's unserialize(), enabling arbitrary PHP object injection. Exploitation requires a high-privileged administrator to configure a crawler-enabled page and a Scheduler task pointing at an attacker-controlled endpoint, so while impact is full RCE on the TYPO3 host, it is gated by an unusual combination of admin access, user interaction, and externally reachable malicious URLs. No public exploit identified at time of analysis and no CISA KEV listing.
Insecure deserialization in Significant-Gravitas AutoGPT platform versions 0.6.34 through 0.6.51 lets an attacker who can poison entries in the shared Redis cache achieve arbitrary command execution inside the backend container. The backend's read path invokes pickle.loads on cache bytes with no HMAC, signature, or schema gate, so any attacker-controlled value reaching that key becomes code on retrieval. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV; the vendor shipped a fix in autogpt-platform-beta-v0.6.52.
Remote code execution in APScheduler (all versions through 3.10.x and 4.0.0a5) is achievable when applications deserialize attacker-controlled data via the bundled JSONSerializer or CBORSerializer. The unmarshal_object routine dynamically imports modules and invokes __setstate__ on arbitrary classes, letting an attacker pivot an untrusted payload into code execution; publicly available exploit code exists, though EPSS remains low at 0.06% (19th percentile).
Remote code execution in FreePBX versions below 16.0.71 and 17.0.6 allows authenticated low-privileged users with backup access to execute arbitrary PHP code by uploading a malicious tar archive containing a crafted manifest file. The backup module passes attacker-controlled data directly to PHP's unserialize() without class restrictions, enabling PHP object injection that runs as the asterisk or www-data web server user. No public exploit identified at time of analysis, though the upstream fix commits are public on GitHub, making patch-diff exploitation feasible.
Unauthenticated remote code execution in SGLang (the LLM/multimodal generation serving runtime) affecting version 5.10 arises when the non-default `--enable-custom-logit-processor` flag is set, allowing attacker-supplied Python objects to be deserialized via `dill.loads()` and execute arbitrary code on the inference host. No CISA KEV listing exists and SSVC records exploitation as 'none', but a public technical write-up (antiproof.ai, 'Three RCEs in SGLang') details the flaw and SSVC marks it automatable with total technical impact. EPSS is modest at 0.32% (55th percentile), consistent with a serious-but-conditional (feature-gated) issue rather than mass exploitation.
Unauthenticated remote code execution affects SGLang, an LLM/multimodal inference-serving framework, at version 5.10, where the generation runtime scheduler's ZeroMQ ROUTER socket binds to 0.0.0.0 by default and deserializes incoming messages with pickle.loads(). Any attacker who can reach the exposed scheduler port can send a crafted pickle payload to execute arbitrary code on the host with full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis, though a vendor-independent technical writeup ('three RCEs in sglang') describes the flaw; EPSS is low (0.05%) and SSVC records no observed exploitation, but the issue is rated automatable with total technical impact.
Path traversal in SimpleSAMLphp's CAS server module allows unauthenticated remote attackers to read and deserialize arbitrary files outside the ticket directory via crafted ticket parameters. When using FileSystemTicketStore, attackers can inject '../' sequences into CAS validation endpoints to escape the configured directory, potentially deleting files that contain serialized PHP data compatible with array types. The vulnerability has a CVSS score of 8.6 with no public exploits identified at time of analysis.
Unsafe deserialization in LangSmith SDK's prompt pull methods allows remote attackers to execute server-side request forgery (SSRF) and redirect LLM traffic to attacker-controlled infrastructure when applications pull public prompts from LangSmith Hub. The SDK deserializes untrusted prompt manifests containing serialized LangChain objects with attacker-controlled constructor arguments, including malicious base_url configurations, custom headers, and secret references. Exploitation requires user interaction (developers must call pull_prompt with a malicious owner/name identifier), but no authentication is required to publish malicious prompts to the public Hub. Vendor-released patches in Python >= 0.8.0 and JS/TS >= 0.6.0 now block public prompt pulling by default, requiring explicit opt-in via dangerously_pull_public_prompt flag. EPSS data not available; no CISA KEV listing or public exploit identified at time of analysis.
Remote code execution in F5 BIG-IP and BIG-IQ Configuration utility allows authenticated attackers with low privileges to execute arbitrary code with high impact to confidentiality, integrity, and availability. The vulnerability stems from unsafe deserialization (CWE-502) in the management interface, exploitable over the network with low attack complexity and no user interaction required. Vendor-released patch available per F5 advisory K000156761. No public exploit identified at time of analysis, with CVSS 8.8 indicating critical severity for environments where attackers have valid low-privilege credentials to the Configuration utility.
PHP Object Injection vulnerability in coreActivity activity logging plugin through version 3.0 allows remote attackers to trigger persistent Denial of Service blocking administrator access to log pages. Unauthenticated attackers inject crafted PHP serialized payloads via User-Agent headers during any logged event (e.g., failed login). When administrators view the Logs page, the plugin deserializes untrusted data and passes it to DeviceDetector::setUserAgent(), causing Fatal TypeError. Vendor-released patch version 3.1 available (released May 6, 2026). EPSS exploitation probability not available; no CISA KEV listing at time of analysis. CVSS 8.1 reflects high complexity attack requiring precise payload crafting despite no authentication requirement.
Arbitrary code execution in Adobe Connect (versions 2025.9.15, 2025.8.157 and earlier) stems from insecure deserialization of untrusted data (CWE-502) and runs in the context of the current user. Exploitation requires the victim to visit a maliciously crafted URL or interact with a compromised web page, so it is user-interaction gated rather than fully automatic. There is no public exploit identified at time of analysis and it is not on the CISA KEV list; EPSS is modest at 1.50% (81st percentile), consistent with SSVC scoring exploitation as 'none' despite a 'total' technical impact.
Remote code execution in Microsoft SharePoint (Enterprise Server 2016, Server 2019, and Subscription Edition) allows an authenticated attacker to run arbitrary code on the server by submitting maliciously crafted serialized data (CWE-502). An authorized user holding only low-level site privileges can escalate to full server compromise over the network with no user interaction. No public exploit identified at time of analysis, and CISA SSVC records exploitation status as 'none'; EPSS sits at 0.50% (66th percentile), indicating modest near-term exploitation probability despite the high CVSS 8.8 score.
Remote code execution in Microsoft SharePoint Server (Enterprise Server 2016, Server 2019, and Subscription Edition) allows an authenticated attacker (PR:L) to run arbitrary code over the network by submitting maliciously crafted serialized data that the server deserializes without validation. Microsoft has released a patch and no public exploit identified at time of analysis; EPSS is modest at 0.50% (66th percentile) and CISA SSVC rates exploitation as 'none' but technical impact as 'total'. The bug follows the well-known SharePoint deserialization RCE pattern (CWE-502), making it a high-value target for post-authentication lateral movement and full server compromise.
Remote code execution in Microsoft SharePoint Server (2016, 2019, and Subscription Edition) allows an authenticated attacker to run arbitrary code across the network by submitting maliciously crafted serialized data (CWE-502). Any user holding low-privilege authenticated access to the SharePoint web application can achieve total compromise of the server (C:H/I:H/A:H). There is no public exploit identified at time of analysis, and the EPSS probability is modest at 0.50% (66th percentile), but the impact is total and a vendor patch is already available.
Remote code execution in Microsoft SharePoint Server (2016, 2019, and Subscription Edition) allows an authenticated attacker with low-level site privileges to run arbitrary code across the network by submitting maliciously crafted serialized data (CWE-502). Microsoft has released a patch; there is no public exploit identified at time of analysis, and the EPSS score is low (0.31%, 55th percentile), with CISA's SSVC framework rating exploitation status as 'none' but technical impact as 'total'. The combination of authenticated-but-low privilege access and full compromise of confidentiality, integrity, and availability makes this a meaningful escalation-to-RCE risk in enterprise collaboration environments.
Remote code execution in Microsoft SharePoint (Enterprise Server 2016, Server 2019, and Server Subscription Edition) allows an authenticated attacker to run arbitrary code over the network by supplying maliciously crafted serialized data (CWE-502). Any user holding valid low-privilege credentials on the SharePoint farm can achieve total compromise of confidentiality, integrity, and availability. There is no public exploit identified at time of analysis, and CISA SSVC records exploitation status as none; EPSS is a modest 0.50% (66th percentile).
Remote code execution in Snorkel machine learning library (≤v0.10.0) occurs when users load untrusted model files via MultitaskClassifier.load(). The vulnerability exploits insecure Python object deserialization through torch.load(), allowing attackers to embed malicious code in model weight files that executes upon loading. EPSS score of 0.06% (19th percentile) suggests low observed exploitation probability in the wild, though SSVC framework indicates total technical impact once exploited. No public exploit code or active exploitation confirmed at time of analysis, but exploitation requires only that a data scientist or ML engineer load a malicious .pkl model file.
Remote code execution in Adversarial Robustness Toolbox (ART) through version 1.20.1 allows unauthenticated network attackers to execute arbitrary Python code by uploading malicious PyTorch model files to pipeline-accessible object storage locations. The vulnerability stems from unsafe use of torch.load() without the weights_only=True parameter in the Kubeflow component's model loading process, enabling Pickle deserialization of arbitrary objects. With CVSS 9.8 (AV:N/AC:L/PR:N/UI:N) but only 0.06% EPSS exploitation probability (19th percentile), this represents a critical-severity issue with low observed real-world targeting, likely due to the specialized nature of ML robustness evaluation deployments. No active exploitation confirmed (not in CISA KEV) and no public exploit code identified at time of analysis.
Remote code execution in Mamba language model framework (through version 2.2.6) allows unauthenticated attackers to execute arbitrary Python code by publishing malicious models on HuggingFace Hub. When victims call MambaLMHeadModel.from_pretrained() on a weaponized model repository, insecure pickle deserialization executes attacker-controlled code in the context of the victim's process. Despite the critical CVSS 9.8 score and network attack vector requiring no authentication, EPSS probability remains extremely low (0.02%, 5th percentile), suggesting limited real-world exploitation to date. No CISA KEV listing or public POC identified at time of analysis.
Remote code execution in Ludwig framework ≤0.10.4 allows unauthenticated network attackers to execute arbitrary code by supplying a malicious PyTorch model file to the ludwig serve endpoint. The vulnerability stems from unsafe deserialization in the model loading component, which uses torch.load() without the weights_only=True safety parameter. With CVSS 9.8 (critical network vector, no authentication required) but only 0.02% EPSS, this represents a high-severity issue in vulnerable deployments, though widespread exploitation has not been observed. No CISA KEV listing or public POC identified at time of analysis.
Remote code execution in Optimate's neural_magic_training.py script allows authenticated attackers to execute arbitrary code via malicious PyTorch model files. The vulnerability stems from unsafe deserialization when loading model state dictionaries without PyTorch's weights_only=True security flag, enabling pickle-based arbitrary object execution. With an EPSS score of 0.06% and no confirmed exploitation, this represents a moderate risk primarily in environments where users can upload or specify model files.
Arbitrary code execution occurs in PyTorch Lightning 2.6.0 and earlier when loading malicious checkpoint files. The LightningModule.load_from_checkpoint() method deserializes untrusted Pickle data without security restrictions, allowing attackers to execute arbitrary Python code when victims open crafted .ckpt files. EPSS score of 0.06% (19th percentile) indicates low observed exploitation probability, and no public exploit code or CISA KEV listing exists at time of analysis. Attack requires local access and user interaction (opening a malicious checkpoint), limiting remote attack scenarios to social engineering or supply chain compromise.
Arbitrary code execution in imgaug library (versions through 0.4.0) occurs when the BackgroundAugmenter class deserializes malicious pickle payloads without validation in its multiprocessing worker method. Attackers who can influence queue data-through compromised shared queues, malicious input scripts, or social engineering-can achieve remote or local code execution depending on deployment context. CVSS 9.8 critical severity reflects network-based exploitation without authentication, though EPSS probability is low (0.02%, 6th percentile), indicating limited observed exploitation activity. No CISA KEV listing or public exploit code identified at time of analysis.
Insecure deserialization in Optimate's neural_magic_training.py script enables remote code execution when loading PyTorch model files. The _load_model() function uses torch.load() without the weights_only=True security parameter, allowing attackers with low privileges to execute arbitrary Python code by providing malicious .pt or .pth files via the --model command-line argument. EPSS indicates low exploitation probability at 0.06% with no active exploitation confirmed.
Arbitrary code execution in Snorkel machine learning library (≤v0.10.0) occurs when users load malicious model checkpoint files through the Trainer.load() method. The vulnerability stems from unsafe PyTorch deserialization that processes untrusted Pickle objects without the weights_only security parameter. Attackers can embed malicious Python code in model files distributed through repositories, shared datasets, or social engineering campaigns. Despite the 8.8 CVSS score indicating critical severity, EPSS scoring at 0.06% (19th percentile) suggests very low real-world exploitation probability, and no active exploitation or public proof-of-concept has been identified at time of analysis.
Arbitrary code execution in Snorkel library (Python) through version 0.10.0 enables remote attackers to execute code by supplying malicious pickle files to the BaseLabeler.load() method. The vulnerability stems from unsafe deserialization using pickle.load() without input validation, allowing attackers to craft serialized objects that execute arbitrary commands during deserialization. With EPSS at 6th percentile, exploitation probability remains relatively low despite the critical CVSS score, and no active exploitation (KEV) or public proof-of-concept has been identified at time of analysis.
Arbitrary code execution via torch-checkpoint-shrink.py script in ml-engineering project allows remote attackers to execute malicious Python code by providing crafted PyTorch checkpoint files. The vulnerability stems from insecure deserialization where torch.load() processes .pt files without the weights_only=True safeguard, enabling pickle-based arbitrary object instantiation. Despite a critical CVSS 9.8 score, EPSS probability is low (0.06%, 19th percentile) and no public exploit or active exploitation is confirmed, suggesting limited real-world targeting to date. SSVC assessment indicates total technical impact with automatable exploitation potential, making this a priority for organizations using ml-engineering scripts in production environments.
Remote code execution in Horovod distributed training framework (versions through 0.28.1) allows unauthenticated network attackers to execute arbitrary code on worker nodes by injecting malicious pickle payloads into the KVStore HTTP server. The vulnerability combines unauthenticated write access to the KVStore coordination server with unsafe deserialization using cloudpickle.loads(), enabling trivial exploitation against any reachable Horovod cluster. EPSS score of 0.12% (31st percentile) suggests low widespread exploitation probability despite critical CVSS 9.8 rating, and no active exploitation confirmed (not in CISA KEV). Public exploit development is highly feasible given the straightforward attack path and publicly documented details.
Arbitrary code execution in Ludwig framework ≤0.10.4 occurs when attackers supply malicious pickle files to the predict() method, which deserializes untrusted data without validation using pandas.read_pickle(). Remote unauthenticated attackers can achieve full system compromise by exploiting the automatic file format detection mechanism that processes .pkl files through Python's unsafe pickle module. EPSS score of 0.06% (19th percentile) suggests low current exploitation likelihood despite the critical CVSS 9.8 rating, though no public exploit code or active exploitation has been identified at time of analysis.
Remote code execution in CosyVoice (FunAudioLLM's open-source text-to-speech toolkit) up to commit 6e01309 allows an attacker to run arbitrary Python on a victim's host when the victim loads an attacker-supplied model directory. The flaw stems from calling torch.load() without weights_only=True, so malicious pickle payloads embedded in .pt model files execute during model loading via the web interface. There is no public exploit identified at time of analysis and EPSS is very low (0.05%, 17th percentile), but SSVC rates the technical impact as total.
Unsafe Python pickle deserialization in pgAdmin 4 FileBackedSessionManager allows authenticated local users with session-directory write access to execute arbitrary code as the pgAdmin process. The vulnerability arises from deserializing session files before validating their HMAC signature, enabling payload injection through crafted pickle objects. Attackers require both valid authentication and filesystem write permission to the sessions directory-achievable through misconfiguration or chaining with a separate path-traversal vulnerability. EPSS exploitation probability and KEV status not provided; no public exploit code identified at time of analysis. PostgreSQL maintainers confirmed the flaw and patched it in version 9.15 by implementing pre-deserialization HMAC validation.
Arbitrary code execution in CosyVoice (FunAudioLLM's multilingual text-to-speech toolkit) through commit 6e01309 allows an attacker to run code on a victim's machine via a malicious PyTorch .pt file. The vulnerability lives in the make_parquet_list.py data-preparation tool, which calls torch.load() without weights_only=True, so any .pt file it ingests can carry a malicious pickle payload that executes when the victim processes an attacker-supplied data directory. Reported by MITRE with a low EPSS (0.02%, 5th percentile) and no public exploit identified at time of analysis; this is a poisoned-input/supply-chain style flaw rather than a remotely reachable network service.
Arbitrary code execution in CosyVoice (FunAudioLLM's open-source multilingual text-to-speech toolkit) arises because its average_model.py utility calls PyTorch's torch.load() on epoch_*.pt checkpoint files without weights_only=True, allowing pickle-based deserialization of attacker-controlled objects. Any user who runs the model-averaging tool against a directory containing a malicious checkpoint executes attacker code on their machine. There is no public exploit identified at time of analysis and EPSS is very low (0.02%), but the CWE-502 pattern is trivially weaponizable and SSVC marks it automatable.
Arbitrary code execution in the Dao-AILab flash-attention training framework (all revisions up to and including commit e724e2588cbe754beb97cf7c011b5e7e34119e62) arises because its checkpoint-loading paths call PyTorch's torch.load() without weights_only=True, permitting pickle-based deserialization of attacker-controlled objects. Any user who warmstarts or evaluates a model from an untrusted checkpoint file triggers code execution on their host. No public exploit is identified at time of analysis, EPSS is negligible (0.02%), and SSVC records exploitation as 'none' - this is a latent supply-chain/ML-artifact risk rather than an actively exploited one.
Arbitrary code execution in CosyVoice's gRPC server (through commit 6e01309e) occurs because the speech-synthesis model is loaded via torch.load() without weights_only=True, deserializing untrusted pickle data. Any operator who starts the gRPC server against an attacker-supplied model directory executes embedded Python code during initialization. No public exploit has been identified and it is not in CISA KEV; EPSS is negligible at 0.02% (5th percentile), consistent with a file-delivery attack rather than mass remote exploitation.
Unsafe deserialization in LangChain (langchain-core >= 1.0.0a1, <= 1.3.2 and <= 0.3.84) lets attackers who can place structured input into preserved run data revive arbitrary trusted LangChain-serializable objects via legacy runtime paths that call load() with allowed_objects="all". Affected surfaces include RunnableWithMessageHistory, astream_log(), and astream_events(version="v1"); a companion _is_lc_secret marker bypass lets crafted constructor dictionaries survive dumps()->loads() round-trips. Impact ranges from persistent chat-history poisoning and downstream prompt injection to possible credential disclosure or SSRF if a revived object touches environment secrets or network clients during initialization; no public exploit is identified at time of analysis and EPSS is negligible (0.01%).
Remote code execution in SEPPmail Secure Email Gateway via insecure deserialization allows unauthenticated attackers to execute arbitrary code through the GINA UI interface. Versions prior to 15.0.4 deserialize untrusted data without validation, enabling attackers to send crafted serialized objects that execute upon processing. CVSS 9.2 reflects network-accessible attack with low complexity requiring only present attack conditions, though no active exploitation (KEV) or public POC has been identified at time of analysis.
PHP object injection in User Frontend plugin for WordPress versions up to 4.3.1 allows authenticated attackers with Subscriber-level access or above to achieve remote code execution via unsafe deserialization of the wpuf_files parameter during form submission. The vulnerability chains input validation failures during form processing with unconditional use of maybe_unserialize() when rendering post content, enabling attackers to inject malicious PHP objects that can execute arbitrary code, delete files, or trigger other attacks through available Property-Oriented Programming (POP) chains. Wordfence disclosed detailed code references showing the vulnerable data flow across multiple plugin files including wpuf-functions.php, FieldableTrait.php, and Frontend_Form_Ajax.php, with both trunk and version 4.2.10 code paths exhibiting the flaw.
LINQPad before 5.52.01 Pro edition is vulnerable to Unsafe Deserialization in LINQPad.AutoRefManager::PopulateFromCache(), leading to code execution. Rated high severity (CVSS 7.3), this vulnerability is low attack complexity. Public exploit code available and no vendor patch available.
Denial of service in Nerdbank.MessagePack (NuGet, versions < 1.1.62) allows a remote unauthenticated attacker to crash any .NET process that deserializes untrusted MessagePack into a type graph containing a DateTime. A tiny crafted payload declares an oversized timestamp extension length, which is propagated unvalidated into a stackalloc on the streaming reader's slow path, producing an uncatchable StackOverflowException that terminates the process. No public exploit identified at time of analysis and EPSS is very low (0.04%), but the attack is trivial and a vendor patch (1.1.62) is available.
Remote denial of service in Apache OpenNLP versions before 2.5.9 and 3.0.0-M3 allows unauthenticated attackers to crash JVM processes by uploading malicious .bin model files that trigger OutOfMemoryError through unbounded array allocation. Exploitation requires no authentication (AV:N/AC:L/PR:N) and affects any code path deserializing binary model files from untrusted sources. EPSS score of 0.02% (5th percentile) suggests low widespread exploitation risk, and no active exploitation or public POC has been identified at time of analysis. Vendor-released patches are available with default safeguards limiting count fields to 10 million entries.
Unauthenticated PHP object injection in Profile Builder Pro for WordPress allows remote attackers to execute arbitrary code by deserializing malicious objects through an unprotected AJAX endpoint. The vulnerability affects all versions through 3.14.5 and stems from unsafe deserialization of attacker-controlled POST data in the wppb_request_users_pins_action_callback() handler, which was registered for both authenticated and unauthenticated users without nonce verification. With CVSS 8.1 and AC:H complexity, exploitation requires chaining with a POP gadget chain, though EPSS data and KEV status are not available to confirm active exploitation.
Remote code execution in Apache MINA 2.1.0-2.1.11 and 2.2.0-2.2.6 allows unauthenticated attackers to execute arbitrary code via unsafe deserialization. The fix for prior CVE-2024-52046 was incomplete-the classname allowlist protecting IoBuffer.getObject() was applied too late, allowing malicious static initializers to execute before filtering. Confirmed actively exploited (CISA KEV). EPSS exploitation probability not provided, but the network-accessible, unauthenticated attack vector (CVSS:3.1/AV:N/AC:L/PR:N/UI:N) combined with KEV status indicates immediate patching is critical for applications calling IoBuffer.getObject().
Remote unauthenticated code execution in Apache MINA 2.1.0-2.1.11 and 2.2.0-2.2.6 allows attackers to bypass class allowlist protections via unsafe deserialization. The vulnerability exists because the fix for CVE-2026-41635 was not backported to the 2.1.X and 2.2.X branches, leaving AbstractIoBuffer.resolveClass() susceptible to arbitrary class instantiation when applications call IoBuffer.getObject(). Only applications actively using MINA's deserialization features are affected. EPSS data not available; no KEV listing or public POC identified at time of analysis.
Unsafe deserialization in Zurich Instruments LabOne Q enables arbitrary code execution when users load malicious experiment files. The import_cls mechanism accepts unvalidated class names from serialized data, allowing attackers to instantiate arbitrary Python classes with controlled constructor arguments. Exploitation requires user interaction to open a crafted file, making this a credible vector for supply chain attacks via shared experiment configurations or support tickets. CVSS 8.4 reflects local attack vector with user interaction requirement. No confirmed active exploitation or public POC at time of analysis.
Remote code execution in MixPHP Framework 2.x through 2.2.17 allows unauthenticated network attackers to execute arbitrary code via unsafe deserialization. The FileHandler class processes session and cache data using PHP's unserialize() on filesystem-sourced content without validation, enabling object injection attacks. CVSS 9.8 critical severity with network attack vector and no privileges required. SSVC assessment confirms automatable exploitation with total technical impact. No active exploitation confirmed at time of analysis (not in CISA KEV), but publicly available proof-of-concept exists (GitHub gist reference).
Client-side remote code execution affects MixPHP Framework 2.x through 2.2.17 when sync-invoke clients connect to attacker-controlled servers. The vulnerability enables malicious servers to execute arbitrary code on connecting clients through unsafe deserialization of server responses (CWE-502). EPSS data unavailable, but SSVC indicates no confirmed exploitation and non-automatable attack complexity aligns with CVSS AC:H rating. Primary risk exists in scenarios where MixPHP clients connect to untrusted external services or where server infrastructure could be compromised.
Remote unauthenticated code execution in MixPHP Framework 2.x through 2.2.17 allows attackers to execute arbitrary PHP code by injecting malicious serialized objects into Redis-backed session or cache storage. The framework's RedisHandler directly deserializes untrusted data from Redis using PHP's unserialize() function without validation. CVSS 9.8 with network vector, low complexity, and no privileges required. EPSS and KEV status not provided; SSVC framework marks this as automatable with total technical impact, indicating high exploitability despite no confirmed active exploitation at time of analysis.
Arbitrary code execution in MixPHP Framework 2.x through 2.2.17 allows local attackers to execute malicious PHP closures via unauthenticated TCP connections to the sync-invoke server. The vulnerability stems from unsafe deserialization of untrusted data on localhost-bound port 127.0.0.1, where Server.php directly passes socket data to Opis\Closure\unserialize() and executes the result without authentication or signature verification. Exploitation requires local network access or SSRF capability against the application server. No public exploit code identified at time of analysis, but the attack mechanism is straightforward for attackers with PHP deserialization knowledge.
Remote code execution in Hyperledger fabric-sdk-java (all versions 1.0.0 through 2.2.26) allows unauthenticated attackers to execute arbitrary commands via malicious serialized Java objects. The deprecated SDK's Channel.java class deserializes untrusted byte arrays without input filtering in readObject() and deSerializeChannel() methods, enabling classic Java gadget chain exploitation. Publicly available exploit code exists (ysoserial toolkit), and exploitation requires only that an application accept Channel serialization data from attacker-controlled sources such as compromised files, external APIs, or injected parameters. EPSS data unavailable; not listed in CISA KEV. Vendor has published GHSA advisory but provides no patch-remediation requires migration to the replacement fabric-gateway SDK.
Server-side request forgery and potential remote code execution affect PhpOffice PhpSpreadsheet when an application passes an attacker-controlled filename to IOFactory::load or any Reader. Because the File::assertFile helper validates paths with is_file(), which is PHP stream-wrapper aware, an attacker can supply phar://, ftp://, or ssh2.sftp:// paths to force outbound connections (SSRF) or trigger phar metadata deserialization (CWE-502) leading to code execution if a usable POP gadget exists. Publicly available exploit code exists (PoC in the GitHub advisory); it is not in CISA KEV and EPSS is low (0.10%), indicating no observed widespread exploitation yet.
Remote code execution in NVIDIA FLARE SDK allows authenticated attackers to execute arbitrary code by sending maliciously crafted FOBS-encoded messages that exploit unsafe deserialization in the FOBS component. The vulnerability affects federated learning deployments where NVIDIA FLARE SDK processes messages from low-privileged authenticated users, enabling complete system compromise with high impact to confidentiality, integrity, and availability. No active exploitation confirmed (not in CISA KEV) and public exploit status unknown at time of analysis.
Unsafe Java deserialization in Apache Camel's camel-consul component (ConsulRegistry / ConsulRegistryUtils.deserialize) lets an attacker who can write to the backing Consul KV store achieve arbitrary code execution inside the Camel process. Any deployment using a Consul-backed Camel registry on versions 3.0.0 up to 4.14.6 or 4.15.0 up to 4.18.1 is affected. There is no public exploit identified at time of analysis, EPSS is low (0.08%), and this is a missed instance of the same deserialization class fixed in CVE-2024-22369, CVE-2024-23114 and CVE-2026-25747.
Message header injection in Apache Camel's camel-mail component (3.0.0 before 4.14.6 and 4.15.0 before 4.18.1) lets an attacker who can email a monitored mailbox smuggle Camel-prefixed MIME headers into the Exchange. Because MailHeaderFilterStrategy filters only the outbound direction and never sets an inbound filter, inbound Camel headers reach downstream components such as camel-bean, camel-exec, or camel-sql where they can alter route behavior, potentially reaching command or query execution. There is no public exploit identified at time of analysis and EPSS is very low (0.02%), but the vendor rates it CVSS 9.4 and SSVC marks it automatable.
Unsafe Java deserialization in Apache Camel's camel-infinispan component allows arbitrary code execution when the ProtoStream-based remote aggregation repository reads objects from an Infinispan cache using java.io.ObjectInputStream with no ObjectInputFilter applied. Any attacker able to write to the backing Infinispan cache can plant a malicious serialized gadget that executes in the application context during routine get/recover operations. Publicly available exploit code exists, though EPSS is low (0.08%) and there is no evidence of active exploitation.
