Deserialization

PHP Object Injection leading to remote code execution affects the Pimcore DXP/CMS (composer pimcore/pimcore) in versions 2026.1.0-2026.1.5 and all 12.3.x through 12.3.9, where the Hotspotimage DataObject field marshaller deserializes the persisted `*__hotspots` object-store column with no class allowlist. Any attacker able to write crafted PHP-serialized bytes into that column gains arbitrary object instantiation on the next object load, chainable to RCE via gadgets in Pimcore's own bundled dependencies (guzzlehttp/guzzle 7.11.0). A working proof-of-concept demonstrating attacker-controlled file write is published in the vendor advisory; publicly available exploit code exists, but there is no CISA KEV listing and no EPSS score was provided.

Remote code execution in the Rank Math SEO WordPress plugin (versions <= 1.0.276) is reachable by any user holding WordPress Author-level privileges, exploiting unsafe PHP deserialization (CWE-502) to execute arbitrary server-side code. The CVSS vector (AV:N/AC:L/PR:H) confirms the attack is network-delivered with low complexity once Author credentials are in hand, yielding full confidentiality, integrity, and availability compromise of the host. No active exploitation confirmed in CISA KEV and no public proof-of-concept has been identified in the available intelligence at time of analysis.

CPU exhaustion in SvelteKit's experimental remote form deserialization endpoint allows unauthenticated remote attackers to render affected servers unresponsive by submitting malformed form data, resulting in denial of service. Versions 2.49.0 through 2.52.1 of @sveltejs/kit are affected, but only when both the experimental.remoteFunctions and form features are simultaneously enabled - a non-default, opt-in configuration. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis; the CVSS 4.0 score of 8.7 reflects the complete availability impact against network-reachable endpoints with no authentication barrier once the experimental features are active.

Memory exhaustion in @sveltejs/kit versions 2.49.0 through 2.52.1 allows unauthenticated remote attackers to crash the server process by sending malformed form data to a remote function endpoint, resulting in complete denial of service. Exploitation is gated behind two simultaneous non-default opt-in conditions - the experimental.remoteFunctions flag and form usage - which significantly narrows the real-world attack surface relative to the CVSS 4.0 score of 8.7. No public exploit or CISA KEV listing has been identified; a vendor-released patch is available in version 2.52.2.

Denial of service in SvelteKit versions 2.49.0 through 2.53.2 is achievable by unauthenticated remote attackers who submit crafted multipart form requests that exploit a deserialization expansion flaw in the experimental `form` remote function, causing the server to construct disproportionately large `files` arrays and exhaust processing resources. Exploitation is gated behind a non-default opt-in flag (`experimental.remoteFunctions: true`) and requires the application to process the `files` array without length or size validation, substantially narrowing real-world exposure despite the CVSS 4.0 score of 8.7. No public exploit has been identified at time of analysis and the vulnerability does not appear in the CISA KEV catalog.

Unauthenticated PHP object injection in the GiveWP WordPress donation plugin (all versions through 4.16.7.1) lets remote attackers reach a deserialization sink and chain it into remote code execution on the hosting server. The flaw is network-reachable with no authentication or user interaction and carries a maximum CVSS of 10.0; Patchstack's public write-up details the full object-injection-to-RCE chain, though no in-the-wild exploitation has been confirmed. Because GiveWP handles donation and payment workflows, a successful attack fully compromises the site and any donor data it processes.

Unauthenticated remote code execution in SOY CMS arises from unsafe deserialization of attacker-controlled data (CWE-502), letting a remote attacker run arbitrary code with the privileges of the web server process. The flaw was coordinated through JPCERT/CC and JVN (JVN04485476) and carries a CVSS 4.0 base score of 9.3. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the deserialization root cause and network-reachable, no-authentication vector make it high priority.

PHP object injection via unsafe deserialization in the User Frontend WordPress plugin (versions before 4.3.10) grants Editor-level users the ability to execute arbitrary PHP code on the host server. The plugin fails to validate field type definitions and deserializes user-controlled post metadata at render time - a CWE-502 flaw exploitable through any available POP chain present in the WordPress environment. A public proof-of-concept exists per WPScan, though SSVC assessment notes no confirmed active exploitation at time of analysis.

Authenticated SQL injection in WatchGuard Dimension's scheduled report feature permits arbitrary OS command execution as the Dimension WebUI process user. All versions of the product are listed as potentially affected per CPE data, with exploitation requiring a valid session holding report administration permissions. No public exploit code or CISA KEV listing has been identified at time of analysis, though the post-authentication command execution capability represents a critical risk for any deployment where report admin credentials can be obtained.

Authenticated SQL injection in WatchGuard Dimension's audit report feature enables privilege escalation to arbitrary OS command execution, running as the Dimension WebUI process account. The vulnerability is exploitable by any user holding report administration permissions, making it a significant lateral-movement and post-compromise pivot risk within WatchGuard-managed network environments. No public exploit code or CISA KEV listing has been identified at time of analysis, though the chained SQL injection-to-command-execution primitive is high impact for attackers who have obtained admin-level credentials.

Arbitrary code execution in SpeechBrain before v1.1.1 is triggered during checkpoint candidate enumeration when PyYAML's unsafe loader parses attacker-controlled CKPT.yaml files in the configured checkpoint path. An attacker who can plant a crafted CKPT.yaml - for example via a malicious pretrained model distributed through a public model repository - can embed !!python/object/apply YAML tags that cause Python to instantiate arbitrary objects at parse time, achieving code execution before any checkpoint is ever selected for recovery. No public exploit specific to this CVE has been identified at time of analysis, and it is not listed in the CISA KEV catalog, but the underlying PyYAML unsafe deserialization class is extensively documented and exploit techniques are widely known.

Spring Cloud Stream versions 5.0.0-5.0.2, 4.3.0-4.3.3, and 4.2.0-4.2.6 expose a deserialization of untrusted types flaw that could allow a network-positioned attacker with high privileges and required user interaction to gain limited read and write access to application data. The CVSS vector (AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:L/A:N) reflects heavy exploitation constraints, making real-world abuse unlikely without insider-level access and specific preconditions. No public exploit code has been identified and the vulnerability is absent from CISA KEV at time of analysis.

JdbcMessageStore deserialization allowlist protection in Spring Integration silently fails when the store is configured as a Spring-managed bean, rendering the security control entirely ineffective. Operators who call addAllowedPatterns() to restrict which Java classes can be deserialized from the JDBC message store receive no actual protection - any class remains deserializable despite the configured allowlist - leaving applications exposed to unsafe Java deserialization attacks while operators believe they have hardened the component. Affected across Spring Integration 6.4.x through 7.1.0; no public exploit identified at time of analysis.

Spring for GraphQL applications are vulnerable to Unsafe Deserialization when processing paginated GraphQL queries. Spring for GraphQL 2.0.0 - 2.0.4

PHP Object Injection in the Hash Form WordPress plugin (versions 1.4.1 and earlier) lets remote, unauthenticated attackers inject crafted serialized objects that are deserialized by the plugin, enabling code execution, data tampering, or site compromise depending on available gadget chains. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) rates it 9.8 Critical with no authentication required. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.

PHP Object Injection in the Geo Controller WordPress plugin (the plugin distributed as cf-geoplugin) affects all versions up to and including 8.9.8, allowing unauthenticated remote attackers to inject crafted serialized PHP objects that are deserialized by the application. Because exploitation requires no authentication and the CVSS vector reports full confidentiality, integrity, and availability impact, a suitable gadget chain in the plugin or wider WordPress environment could lead to remote code execution, data disclosure, or site takeover. There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV.

PHP Object Injection in the Fluent Boards Pro WordPress plugin (versions 2.0.11 and earlier) allows authenticated administrators to pass arbitrary serialized PHP data through the editor component, triggering unsafe deserialization on the server and potentially achieving remote code execution, file writes, or full system compromise. The vulnerability is classified as CWE-502 and carries a CVSS 3.1 score of 7.2 (High), with full Confidentiality, Integrity, and Availability impact. No public exploit code or active exploitation via CISA KEV has been identified at time of analysis.

PHP Object Injection in the Booking and Rental Manager WordPress plugin (by magepeopleteam, versions <= 2.7.5) allows an authenticated contributor-level user to pass malicious serialized payloads through unsanitized input handled by the plugin. If a PHP Property-Oriented Programming (POP) chain is present in the WordPress environment - commonly supplied by WooCommerce or co-installed plugins - exploitation can yield full confidentiality, integrity, and availability compromise of the underlying server. No public exploit code has been identified at time of analysis, and this CVE has not been added to the CISA Known Exploited Vulnerabilities catalog.

Denial-of-service in Spring AMQP across multiple supported release lines allows a privileged AMQP publisher to force a System.exit(99) call inside the consumer JVM, killing the entire process rather than isolating the failure to the listener thread. Affected versions span the 2.4.x, 3.2.x, 4.0.x, and 4.1.0 release trains, covering a wide swath of actively maintained Spring deployments. No public exploit code or CISA KEV listing has been identified at time of analysis, but the total, immediate JVM termination and the collateral impact on every co-located workload make this operationally significant in RabbitMQ-integrated Spring environments.

Unsafe Java deserialization in Spring Batch's DefaultExecutionContextSerializer exposes JDBC-backed job repositories to potential gadget-chain attacks across Spring Batch 5.2.6 and earlier and 6.0.0-6.0.4. Base64-decoded bytes are fed directly to ObjectInputStream.readObject() without an ObjectInputFilter type allowlist, meaning any class resolvable from the JVM classpath can be instantiated during deserialization. An attacker able to influence data written to the job repository could leverage available gadget chains to achieve remote code execution. No public exploit has been identified at time of analysis, and the CVE is not listed in CISA KEV.

Arbitrary code execution via Jackson deserialization affects Spring Batch 5.2.0-5.2.6 and 6.0.0-6.0.4 when applications use Jackson2ExecutionContextStringSerializer and read job execution contexts from an untrusted data source. The JobParameterDeserializer's failure to enforce Jackson's trusted-types allowlist exposes the application to well-known Jackson polymorphic deserialization gadget chains, which can yield full remote code execution on the batch server. No public exploit has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog, though the exploitation technique leverages established RCE primitives broadly understood by attackers targeting Java environments.

Unsafe Java deserialization in Spring Integration's SerializingHttpMessageConverter exposes applications to remote code execution via crafted HTTP requests bearing Content-Type: application/x-java-serialized-object. The converter passes the request body directly to a raw java.io.ObjectInputStream.readObject() call with no ObjectInputFilter or class allowlist, meaning any Serializable object - including known gadget-chain payloads - is fully deserialized. Exploitation is conditional on the presence of a compatible gadget library (e.g., Apache Commons Collections) on the classpath, but that condition is frequently met in enterprise Java deployments; no public exploit has been identified at time of analysis and CISA KEV status is not confirmed.

Unsafe deserialization in Spring Integration exposes network-accessible, low-privilege attackers to arbitrary Java class instantiation by manipulating the json__TypeId__ message header, which is resolved via ClassUtils.forName without any type or package allowlist. All maintained Spring Integration branches are affected - 5.5.21 and earlier, 6.4.0-6.4.12, 6.5.0-6.5.10, 7.0.0-7.0.5, and 7.1.0 - making the exposure broad across the Spring ecosystem. No public exploit code or CISA KEV listing has been identified at time of analysis, though the deserialization-via-header-controlled-type pattern is a well-understood Java attack class with a mature exploit toolkit.

Unauthenticated PHP object injection in the ILIAS e-learning platform allows remote attackers to achieve code execution as the web server user via the Shibboleth back-channel logout endpoint (shib_logout.php). The endpoint runs on an authentication-exempt path and passes every live session row's stored data through a hand-rolled parser that calls unserialize() with no class allowlist, so an attacker who first seeds a serialized object into a session row (via the equally unauthenticated LTI entry point) triggers a destructor-based POP chain that writes attacker-controlled JSON to an attacker-chosen path below the web root. No public exploit has been identified at time of analysis, but the flaw is unauthenticated and network-reachable, and the vendor CVSS 4.0 base score is 9.3 (Critical).

The Kaltura HTML5 player (mwEmbed / html5lib) contains an unauthenticated remote code execution vulnerability caused by unsafe data deserialization and unsanitized filesystem path construction. mwEmbedLoader.php accepts a user‑controlled ServiceUrl, whose response is passed to unserialize(), and the resulting object’s fields are written to a cache path derived from attacker‑supplied uiconf_id without proper path validation. An attacker can write arbitrary files into web‑accessible locations and achieve code execution as the webserver user. Affected versions include html5lib v2.45, v2.103 and earlier, and other v2.x releases exposing the vulnerable endpoint.

Arbitrary code execution in the Natural Language Toolkit (NLTK) before 3.10.3 allows attackers to bypass the library's pickle allowlist and run commands when a crafted model or tokenizer artifact is loaded. The allowlist trusts whole module namespaces rather than specific safe callables, so dangerous in-namespace functions can be invoked via pickle's REDUCE opcode. Reported by VulnCheck; no public exploit identified at time of analysis, though the root cause and gadget functions are documented in the advisory.

PHP Object Injection in the Kalles Addons WordPress plugin (all versions up to and including 1.0.6) allows unauthenticated remote attackers to deserialize untrusted PHP objects via a network-accessible deserialization endpoint. Exploitation is strictly conditional: the plugin itself contains no known POP (Property-Oriented Programming) chain, so real-world impact - ranging from arbitrary file deletion and sensitive data retrieval to remote code execution - only materializes when a separately installed plugin or theme on the same WordPress instance supplies a usable POP chain. No public exploit code and no CISA KEV listing have been identified at time of analysis.

PHP Object Injection in the Apache Solr for TYPO3 enterprise search extension allows authenticated low-privileged users to achieve arbitrary code execution on the server when user-generated content can reach indexed fields configured with SOLR_CLASSIFICATION, SOLR_MULTIVALUE, or SOLR_RELATION content object types. The extension's indexer passes multi-value field values rendered by the content object renderer directly to PHP's unserialize() function rather than a safe serialization format, creating a CWE-502 attack surface exploitable via PHP gadget chains. No public exploit code has been identified at time of analysis, though the vulnerability class is well-understood and commonly weaponized; the CVSS 4.0 score of 7.7 reflects the severe potential impact tempered by meaningful exploitation preconditions.

Remote code execution in the TYPO3 'HTML5 Video Player vs. Powermail' extension allows a remote, unauthenticated attacker to achieve arbitrary code execution on the server by supplying a crafted serialized value in an attacker-controlled cookie that is passed to PHP's unserialize(). The flaw is a classic PHP Object Injection (CWE-502) with full confidentiality, integrity, and availability impact and a CVSS 4.0 base score of 9.3. No public exploit identified at time of analysis, but the trivial attack requirements make weaponization straightforward.

Arbitrary code execution in NLTK (Natural Language Toolkit) through 3.9.4 allows attackers to run Python code when a victim application loads a malicious transition-parser model file. The TransitionParser.parse() method deserializes model data via pickle with restricted=False, so an attacker-supplied model embedding pickle gadget chains executes with the privileges of the loading process. No CISA KEV listing or public exploit code is identified at time of analysis, though this class of pickle-RCE bug is trivially weaponizable once a malicious model is delivered.

PHP Object Injection in the WordPress plugin The Events Calendar (all versions up to and including 6.17.2) allows unauthenticated remote attackers to inject crafted serialized PHP objects that are deserialized by the plugin, per CVSS a network, low-complexity, no-authentication issue with high confidentiality, integrity, and availability impact (CVSS 9.8). Depending on the POP gadget chains present in the plugin, its dependencies, or other installed plugins/themes, this can escalate to arbitrary file operations, SQL injection, or remote code execution. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the unauthenticated network vector makes it a high-priority patch target.

Insecure deserialization in weDevs WP Project Manager (WordPress plugin) versions up to and including 4.0.6 allows remote unauthenticated attackers to inject crafted PHP objects (CWE-502) into the application. With CVSS:3.1 base score 9.8 (AV:N/AC:L/PR:N/UI:N) and full confidentiality, integrity, and availability impact, successful exploitation can lead to arbitrary object instantiation and, given a suitable POP gadget chain in the plugin or WordPress core, remote code execution or data compromise. Reported by Patchstack and tracked as ENISA EUVD-2026-65169; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.

PHP Object Injection in the ACPT (Pro) - Custom Post Types plugin for WordPress affects all versions up to and including 2.0.63, allowing an attacker to inject a serialized PHP object that the plugin deserializes. The vendor advisory (Patchstack) frames this as a 'Subscriber' level issue, meaning a low-privileged authenticated account can supply crafted serialized data; where a suitable POP gadget chain exists in the plugin or its dependencies, this can escalate to code execution, data theft, or site compromise. There is no public exploit identified at time of analysis, and the flaw is not listed in CISA KEV.

DNS-based server-side request forgery in jackson-databind exposes any Java application that deserializes user-supplied JSON into objects containing `java.net.InetAddress`-typed fields, causing the library to perform unsolicited outbound DNS lookups against attacker-controlled hostnames. Affected across all major release lines from 2.x through 3.x (com.fasterxml and tools.jackson.core artifact groups), the flaw allows unauthenticated remote attackers to enumerate internal hostnames and map internal network topology via DNS side-channels. No active exploitation or public exploit code has been identified; vendor patches are available across all affected release lines.

PHP object injection in Combodo iTop's user preference functionality prior to version 3.2.3 enables authenticated remote attackers to achieve remote code execution on the underlying server. The vulnerability stems from deserializing attacker-controlled PHP objects without validation, with the CVSS Scope:Changed metric reflecting that successful exploitation escapes the application boundary to compromise the host. No public exploit code or CISA KEV listing has been identified at time of analysis, though the CWE-502 vulnerability class is well-understood and the attack complexity is rated Low once an authenticated session is obtained.

Unsafe pickle deserialization in Flair 0.15.0 and 0.15.1 allows arbitrary code execution with the privileges of the loading process when a victim calls ClusteringModel.load() on an attacker-supplied model file. The critical compounding factor is a false remediation: CVE-2024-10073 designated 0.15.0 as the fixed version after clustering was dropped from the documented API, but flair/models/clustering.py remains physically present in the PyPI-distributed wheels for both 0.15.0 and 0.15.1 and is directly importable, voiding the prior CVE's resolution. No public exploit has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.

PHP Object Injection in the FreightCo WordPress theme (versions up to and including 1.1.15) lets remote attackers pass attacker-controlled serialized data into an unsafe unserialize() call, enabling exploitation of PHP object gadget chains. The flaw is unauthenticated (CVSS 3.1 vector PR:N) and carries a critical 9.8 base score, and per the CVSS vector it can lead to full compromise of confidentiality, integrity, and availability. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, so no active exploitation is confirmed.

Improper input validation in llama.cpp's ggml-RPC Server allows remote unauthenticated attackers to send crafted deserialization payloads targeting the `deserialize_tensor` function, affecting the `op` and `op_params` arguments in `ggml/src/ggml-rpc/ggml-rpc.cpp` at commit bec4772f6. The CVSS 4.0 score of 6.9 (AV:N/AC:L/PR:N/UI:N) reflects network-accessible exploitation with partial confidentiality, integrity, and availability impact on the vulnerable system. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis, and the originating GitHub issue was closed due to inactivity.

PHP Object Injection in PPWP - Password Protect Pages (WordPress plugin, versions up to and including 1.9.18) permits authenticated attackers holding Contributor-level roles or higher to deserialize attacker-controlled data via the 'post_protection_roles' parameter, injecting arbitrary PHP objects into the application. Real-world impact is fully contingent on a Property-Oriented Programming (POP) chain being present in another co-installed plugin or theme - absent that chain, the vulnerability has no exploitable effect, but where one exists, outcomes can include arbitrary file deletion, sensitive data retrieval, or remote code execution. No public exploit code or active exploitation has been identified at time of analysis; however, a Wordfence advisory and a WordPress SVN changeset (3567221) both indicate a fix has been committed.

PHP Object Injection in the WS Form LITE contact form plugin for WordPress (all versions through 1.10.80) lets unauthenticated attackers instantiate arbitrary PHP objects by supplying serialized data in form-submission meta values, which the plugin deserializes without validation. The plugin ships no exploitable POP (property-oriented programming) chain of its own, so on a default install the injection has no direct impact; real damage - arbitrary file deletion, sensitive-data disclosure, or code execution - occurs only when a separate plugin or theme on the same site provides a usable gadget chain. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, so the headline 9.8 rating overstates practical risk for isolated installs.

Path traversal and pickle deserialization protections in NLTK before 3.10.0 are effectively disabled by default - pathsec.py sets ENFORCE=False, causing all security validation to emit warnings rather than raise blocking exceptions. Any application using NLTK to process untrusted file paths or serialized data is exposed unless operators have explicitly overridden this default. No public exploit has been identified at time of analysis, but the attack surface is significant wherever NLTK handles attacker-controlled inputs, particularly given that Python pickle deserialization can enable arbitrary code execution.

Remote code execution in NLTK's TransitionParser component allows arbitrary OS command execution when a victim loads a crafted transition-parser model file. The AllowlistUnpickler in NLTK before 3.10.3 validated only the module string during deserialization, not the global name - enabling attribute traversal via dotted names (e.g., resolving 'sklearn.os.system' through getattr chaining on an allowlisted 'sklearn' namespace) to reach callable sinks the allowlist never intended to expose. No public exploit has been identified at time of analysis, but the CVSS 4.0 score of 8.7 with no authentication prerequisite reflects significant risk for pipelines that ingest externally-sourced NLP models.

Server-Side Request Forgery in PTC Windchill PDMLink and PTC FlexPLM allows unauthenticated remote attackers to induce the server to issue arbitrary internal network requests by submitting maliciously crafted serialized data for deserialization. The underlying root cause is CWE-502 (Deserialization of Untrusted Data), where the deserialization process itself is the vector that triggers the SSRF condition, enabling lateral movement toward backend infrastructure. No public exploit code or CISA KEV listing has been identified at time of analysis, but the combination of network accessibility and no authentication requirement elevates practical risk for internet-exposed deployments.

Remote code execution in PTC Windchill and PTC FlexPLM allows unauthenticated network attackers to execute arbitrary code by submitting maliciously crafted serialized objects that the application deserializes without validation. Rated CVSS 4.0 9.2 (Critical) with full confidentiality, integrity, and availability impact, though the vector's AC:H flag indicates the attack is non-trivial to reliably reproduce. No public exploit identified at time of analysis, and the flaw is not listed in CISA KEV.

Ghidra's PDB parser (all versions before 12.1.3) crashes when processing a crafted PDB file containing an oversized parameters section, enabling denial-of-service against security analysts. The AbstractPdb deserialization routine accumulates all parameters from the PDB stream into an unbounded heap list without size validation; the resulting OutOfMemoryError is a JVM Error subclass that bypasses standard exception handling, causing uncontrolled process termination. No public exploit code exists and no CISA KEV listing is present; exploitation requires a victim analyst to open a malicious file, limiting real-world impact to targeted disruption of reverse-engineering workflows.

Remote code execution in Microsoft Entra ID lets an unauthenticated network attacker run arbitrary code by submitting maliciously crafted serialized data that the service deserializes without validation (CWE-502). The CVSS 3.1 base score is a maximum 10.0 with a scope change, reflecting unauthenticated network reach and full compromise of confidentiality, integrity, and availability. There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV, but the combination of a cloud identity platform and PR:N/UI:N makes this an urgent-patch candidate.

Remote code execution in Hugging Face PyTorch Image Models (timm) version 1.0.24 is triggered when a user loads a crafted model checkpoint file, exploiting unsafe deserialization of untrusted data. The vulnerability, discovered by ZDI (ZDI-CAN-27987) and tracked as ZDI-26-523, allows an attacker who can deliver a malicious checkpoint to achieve full code execution in the context of the victim's process with no special system privileges required. No public exploit has been identified at time of analysis and the vulnerability is not listed in the CISA KEV catalog, but the attack surface is practically significant in ML/AI workflows where downloading pretrained checkpoints from public sources is routine.

Remote code execution in Aeon 1.3.0 is triggered when a user loads a maliciously crafted dataset file via the load_rehab_pile_dataset function, which called numpy's np.load() with allow_pickle=True - enabling full Python pickle deserialization of attacker-controlled content. Reported by Zero Day Initiative (ZDI-CAN-28749 / ZDI-26-468) and tracked as EUVD-2026-63433, the vulnerability carries CVSS 7.8 with full confidentiality, integrity, and availability impact limited by local attack vector and required user interaction. No public exploit has been identified at time of analysis, and an upstream patch commit is available but a tagged release version has not been independently confirmed.

Unauthenticated PHP object injection in the Roxnor FundEngine (wp-fundraising-donation) WordPress plugin through version 1.7.9 lets remote attackers pass attacker-controlled serialized data into a PHP unserialize() sink without authentication. If a suitable POP gadget chain is present in the plugin, WordPress core, or another installed plugin, this can escalate to arbitrary code execution, file operations, or SQL manipulation. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.

PHP Object Injection in the Flatastic WordPress theme (versions 2.0 and earlier, by author monkeysan) lets unauthenticated remote attackers pass attacker-controlled serialized data into a PHP unserialize() call, potentially achieving remote code execution, data theft, or site takeover if a suitable POP gadget chain is present in the WordPress core, plugins, or theme. Reported by Patchstack and rated CVSS 9.8, it requires no authentication or user interaction. No public exploit is identified at time of analysis, and it is not listed in CISA KEV.

Unauthenticated PHP Object Injection in the Forminator WordPress plugin (WPMU DEV) affects all versions up to and including 1.57.0, letting remote attackers submit crafted serialized data that is deserialized without validation to potentially achieve arbitrary object instantiation and, with a suitable POP gadget chain, remote code execution. The vulnerability carries a CVSS 9.8 rating with a fully unauthenticated network vector and complete confidentiality, integrity, and availability impact. No public exploit identified at time of analysis, and it is not listed in CISA KEV.

Unauthenticated remote code execution in InternLM LMDeploy (versions 0.9.2 through 0.15.x) allows a remote attacker to execute arbitrary code inside an inference engine process when disaggregated (P2P) serving is enabled. The disaggregation peer-connector deserializes attacker-influenced ZMQ messages with Python pickle before any type validation, and the /distserve/p2p_initialize and /distserve/p2p_connect endpoints require no authentication in the default configuration (api_keys=None). Reported by VulnCheck with a vendor advisory and a public patch; no public exploit or CISA KEV listing identified at time of analysis, though the code path and fix are publicly documented on GitHub.

Operating-system command execution in the Splunk MCP Server app (all versions below 1.2.1) lets a user already holding the Splunk 'admin' role run arbitrary commands on the underlying host by abusing unsafe deserialization in the credential-management component. Because the app trusts stored data and deserializes it without verifying the object type, a privileged Splunk user can escalate from application-level administration to full host compromise. No public exploit identified at time of analysis, and it is not listed in CISA KEV; a vendor patch is available.

Arbitrary code execution in Splunk AI Toolkit below 6.0.0 is achievable by any user holding the Splunk 'power' role, through loading a crafted model file that embeds malicious pickle payloads inside sparse matrix data. The toolkit's model codec deserializes this data without sanitizing or restricting the embedded pickle content, granting the attacker code execution as the Splunk server process. No public exploit or CISA KEV listing has been identified at time of analysis, but the RCE impact with a low-privilege network vector makes this a high-priority patch target for any Splunk deployment running the AI or Machine Learning Toolkit.

Unauthenticated administrative account takeover in vsDesk (a Russian-market IT service-desk/help-desk platform) lets a remote attacker abuse insecure deserialization of application configuration data to point the login flow at an attacker-controlled LDAP server and provision a new admin account. Rated CVSS 4.0 9.3 (critical) with an unauthenticated network vector, it was researched and disclosed by Kaspersky (klsecservices); a detailed public write-up exists (KLSA-00296), though no CISA KEV listing or confirmed weaponized exploit is present in the data, so this is best characterized as no public exploit code identified at time of analysis despite a thorough advisory.

Remote code execution on the Wazuh cluster master node is achievable by any attacker who controls a cluster worker node, exploiting unsafe Python builtin resolution in the distributed API merge path. Affected versions span 4.0.0 through 4.14.5 and 5.0.0-beta1; the vulnerable code in framework/wazuh/core/results.py called getattr(builtins, type_) with attacker-supplied strings from worker JSON responses, enabling exec or eval injection. No public exploit code has been identified at time of analysis and the vulnerability is not listed in CISA KEV, but the attack primitive is mechanically trivial once a worker node is controlled, with the payload executing as root on the master.

Elevation of privilege via deserialization of untrusted data affects Dell Command Update (DCU) versions prior to 5.7.1 on local systems. A low-privileged local attacker can exploit unsafe deserialization to execute arbitrary code at a higher privilege level, potentially gaining full system control. No public exploit code or active exploitation has been identified at time of analysis, but the high CVSS score and straightforward attack complexity make this a meaningful patching priority for enterprise fleets.

Elevation of privilege in Dell Command Update (DCU) versions prior to 5.7.1 enables a low-privileged local attacker to fully compromise system confidentiality, integrity, and availability through unsafe deserialization of attacker-controlled data. The root cause is CWE-502 (Deserialization of Untrusted Data), a class of vulnerability where malicious serialized objects can trigger unintended code paths during deserialization, resulting in privilege escalation on Dell client endpoints. Dell has released version 5.7.1 as a fix per advisory DSA-2026-309; no public exploit or active exploitation has been identified at time of analysis.

Unauthenticated PHP Object Injection in the WordPress 'Kalles Addons' plugin (by the4) through version 1.0.6 lets remote attackers inject arbitrary serialized PHP objects, potentially escalating to code execution, data theft, or site takeover if a suitable gadget chain is present. The CVSS 9.8 (AV:N/AC:L/PR:N/UI:N) reflects network-reachable, no-authentication, low-complexity exploitation with full confidentiality, integrity, and availability impact. Disclosed via Patchstack; no public exploit identified at time of analysis and the flaw is not listed in CISA KEV.

Unauthenticated PHP object injection in the WP Desk Flexible Subscriptions WordPress plugin (versions <= 1.8.1) lets remote attackers submit crafted serialized data that the plugin deserializes, enabling exploitation of PHP object magic methods. Reported by Patchstack and rated CVSS 9.8, the flaw can escalate to remote code execution, data theft, or site takeover when a suitable POP gadget chain is present in the plugin, WordPress core, or another installed extension. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.

Unsafe Java deserialization in SPLWare esProc through version 20260507 exposes a network-accessible socket endpoint to remote, unauthenticated object injection. The vulnerable class `ObjectInputStream.readUnshared` in `SocketData.java` processes attacker-controlled serialized data without validation, enabling arbitrary object graph instantiation. No public exploit or CISA KEV listing is confirmed at time of analysis, but the unauthenticated network vector and absence of complexity barriers make this a credible remote attack surface requiring prompt patching.

Full takeover of Oracle Outside In Technology 8.5.8 is achievable by a local attacker who can position a malicious file for processing by an authorized user on the same host, exploiting a low-complexity flaw in the Outside In Core parsing engine. The vulnerability affects Oracle Fusion Middleware deployments running OIT 8.5.8 and yields complete compromise of confidentiality, integrity, and availability upon successful exploitation. No public exploit code or CISA KEV listing has been identified at time of analysis, though the low attack complexity (AC:L) and absence of privilege requirements (PR:N) make this straightforward to exploit for any attacker who has already achieved local system access.

Full system takeover via Oracle Outside In Technology 8.5.8 is achievable by a local attacker exploiting a flaw in the PDF Export SDK component, requiring no application-level privileges but depending on human interaction from another user on the same infrastructure. The attack vector is strictly local (AV:L), confining risk to hosts where the SDK executes, yet successful exploitation yields complete confidentiality, integrity, and availability compromise of the affected process and host. No public exploit code or CISA KEV listing has been identified at time of analysis; Oracle addressed the issue in the August 2026 Critical Patch Update.

Use-after-free in Valkey's RESTORE command allows a low-privileged remote attacker to potentially execute arbitrary code by supplying a crafted RDB stream payload that assigns a single Pending Entry List (PEL) NACK to multiple stream consumers. Valkey versions prior to 7.2.14, 8.0.10, 8.1.9, 9.0.5, and 9.1.1 across all active release trains are affected. When one consumer referencing the shared NACK is deleted while another still holds a pointer to the same memory, a use-after-free condition occurs that can corrupt the allocator heap and enable remote code execution. No public exploit or CISA KEV listing exists at time of analysis, though the vendor's own fix PR includes a detailed reproducer test that substantially lowers the barrier to weaponization.

PHP Object Injection in TaxoPress versions up to and including 3.51.0 enables authenticated low-privileged WordPress users to inject malicious serialized PHP objects through the plugin's editor interface. When a suitable Property-Oriented Programming (POP) gadget chain is present in the target WordPress environment, this can escalate to full remote code execution, unauthorized file writes, or complete site compromise. No public exploit or CISA KEV listing has been identified at time of analysis, but the CVSS 8.8 High rating reflects the severe potential impact achievable with low authentication requirements.

Insecure deserialization in the Youzify WordPress plugin (versions 1.3.7 and earlier) allows remote unauthenticated attackers to submit crafted serialized PHP objects that the plugin deserializes without validation, per a Patchstack advisory. Because the CVSS vector is AV:N/AC:L/PR:N/UI:N with high confidentiality, integrity, and availability impact, successful exploitation can lead to object injection and potentially full site compromise. There is no public exploit identified at time of analysis, and it is not listed in CISA KEV.

Unauthenticated PHP Object Injection in the WordPress plugin Popup by Supsystic (versions 1.13.0 and earlier) lets remote attackers submit crafted serialized data that the plugin deserializes without validation. Reported by Patchstack and rated CVSS 9.8, the flaw is exploitable without authentication or user interaction; if a suitable POP gadget chain is present in the WordPress core, another plugin, or theme, it can escalate to arbitrary file operations, SQL injection, or remote code execution. No public exploit identified at time of analysis and it is not listed in CISA KEV.

Unauthenticated PHP Object Injection in the Ultimate Maps by Supsystic WordPress plugin (all versions before 1.5.0) lets remote attackers pass attacker-controlled serialized data into a PHP unserialize() call, instantiating arbitrary PHP objects. If a usable POP (property-oriented programming) gadget chain is present in the plugin, WordPress core, or any other active plugin, this can escalate to remote code execution, file operations, or database compromise. Reported by Patchstack and assigned CVSS 9.8; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.

Unauthenticated PHP object injection affects the Easy Google Maps WordPress plugin (vendor Supsystic) in all versions up to and including 1.13.0, letting remote attackers submit arbitrary serialized PHP objects that the application deserializes.

No public exploit is identified at time of analysis, and the issue is not listed in CISA KEV.

Unauthenticated PHP Object Injection in the RegistrationMagic WordPress plugin (versions <= 6.0.9.7) allows remote attackers to inject crafted serialized PHP objects that are deserialized by the application without validation. Depending on the POP gadget chains available in the plugin, WordPress core, or other installed plugins, this can escalate to arbitrary file operations, SQL injection, or remote code execution. Reported by Patchstack with a CVSS 9.8; no public exploit identified at time of analysis and no CISA KEV listing, so exploitation is not confirmed in the wild.

PHP Object Injection in the OptionTree WordPress plugin (versions <= 2.7.3) enables authenticated administrators to submit crafted serialized PHP data through the plugin's Editor interface, triggering dangerous deserialization that can culminate in arbitrary code execution on the host server. The CVSS vector (PR:H) confirms that exploitation is gated behind WordPress administrator credentials, constraining the immediate threat surface. No public exploit code or active exploitation has been identified at time of analysis.

Unauthenticated PHP Object Injection in the FundEngine WordPress fundraising/donation plugin (slug wp-fundraising-donation) affects all versions up to and including 1.7.9, letting a remote attacker with no authentication inject a crafted serialized PHP object into an application deserialization sink. Given the CWE-502 root cause and the PR:N/UI:N vector, a successful attack can pivot to remote code execution, data theft, or full site takeover when a suitable POP gadget chain is reachable. Reported by Patchstack and rated CVSS 9.8, with no public exploit identified at time of analysis and no CISA KEV listing.

PHP Object Injection in the Essential Real Estate WordPress plugin (≤ 5.3.3) by g5theme allows low-privileged authenticated users to pass a crafted serialized PHP object through a vulnerable unserialize() call, potentially triggering arbitrary code execution if a usable POP (Property-Oriented Programming) gadget chain exists within the WordPress installation. The CVSS 8.8 score reflects full confidentiality, integrity, and availability impact - realistic in WordPress environments where co-installed plugins routinely supply gadget chains. No public exploit code or active exploitation (CISA KEV) has been identified at the time of analysis.

Unsafe deserialization in Progress ShareFile Storage Zones Controller v5.12.5 and below exposes the controller host to arbitrary code execution by any low-privileged user holding write access to a connected network share. Rooted in CWE-502 (Deserialization of Untrusted Data), the flaw processes attacker-controlled file metadata without integrity validation, yielding full host compromise with high confidentiality, integrity, and availability impact. No public exploit code has been identified at time of analysis, and the vulnerability is not currently listed in the CISA Known Exploited Vulnerabilities catalog.

PHP Object Injection in the Turnkey bbPress by WeaverTheme WordPress plugin (all versions through 1.7.1) allows authenticated administrators to pass arbitrary PHP objects through the plugin's settings-restore handler, which reads an uploaded file's raw contents and passes them directly to `unserialize()` without validation. The immediate danger is conditional: no POP chain exists within the plugin itself, but any co-installed plugin or theme supplying a POP chain elevates this to arbitrary file deletion, sensitive data retrieval, or remote code execution. No public exploit has been identified at time of analysis, and no active exploitation is confirmed in CISA KEV.

Arbitrary file deletion leading to remote code execution in the Podlove Podcast Publisher WordPress plugin (all versions through 4.5.3) allows authenticated contributors to destroy critical server files and fully compromise the WordPress installation. The root cause is a PHP deserialization flaw in the shownotes REST API that activates a native POP chain via GenerationGuard::__destruct(), invoking wp_delete_file() on an attacker-controlled path - enabling deletion of wp-config.php to force WordPress into reinstallation mode. No public exploit has been identified at time of analysis and the vulnerability is not listed in CISA KEV, though the POP chain is explicitly mapped in the CVE with source code references, indicating high confidence in exploitability.

Insecure deserialization (CWE-502) in AVEVA Enterprise SCADA and related pipeline/HMI products allows an authenticated operator holding the 'DNA Authority - Operator' role to tamper with serialized data and achieve code execution during deserialization, running under the elevated Enterprise SCADA 'DNA Apps' security group. The flaw affects AVEVA Enterprise SCADA, Enterprise SCADA HMI, Pipeline Operations for Gas/Liquids, Pipeline Integrity Monitor, Pipeline Training Simulator, and Measurement Advisor, and is fixed per AVEVA Security Bulletin AVEVA-2026-005 and CISA advisory ICSA-26-225-01. There is no public exploit identified at time of analysis, but the reported CVSS 4.0 base score is 10.0.

Privilege escalation in Dell Wyse Management Suite (WMS) versions prior to 2605.0.2 allows a low-privileged local attacker to fully compromise the host system through improper deserialization of untrusted data. The vulnerability carries a CVSS 7.8 High score with full confidentiality, integrity, and availability impact scoped to the vulnerable system. No public exploit code has been identified and EPSS places this at the 0th percentile for near-term exploitation likelihood; however, SSVC rates the technical impact as total, meaning successful exploitation results in complete system compromise for any attacker already holding local access.

Unsafe Java deserialization in alldatacenter alldata up to version 0.6.8 exposes the xxl-rpc Listener to remote, unauthenticated exploitation via crafted Hessian2-serialized payloads. The Hessian2Input.readObject() function in HessianSerializer.java processes attacker-controlled input without class validation, enabling object deserialization attacks that can activate gadget chains present in the application's JVM classpath. A public proof-of-concept exploit is available, the project has formally declined to issue a patch, and all users on affected versions face a permanent unmitigated known risk.

Insecure deserialization in IBM WebSphere Application Server - Liberty 17.0.0.3 through 26.0.0.8 enables a low-privileged administrative user to trigger unbounded resource consumption, resulting in denial of service against the application server. The attack requires the restConnector-2.0 administrative feature to be enabled and the attacker to have adjacent network access with valid low-privilege credentials. No public exploit code has been identified at time of analysis, and this CVE is not listed in the CISA Known Exploited Vulnerabilities catalog.

Remote code execution in Apache Shindig (all versions) is reachable via the project's REST API, where deserialization of attacker-controlled input allows server-side arbitrary code execution. The vulnerability requires high-privilege API access (CVSS PR:H), limiting opportunistic exploitation, but every deployed instance is permanently exposed because the Apache Software Foundation has retired the project and will not release a fix. No public exploit or KEV listing has been identified at time of analysis, but the combination of RCE impact and no-patch status makes any continued deployment a long-term liability.

PHP Object Injection in the Booking Activities WordPress plugin (versions ≤ 1.18.4) exposes sites to potential remote code execution through unsafe deserialization of attacker-controlled data. The CVSS vector (PR:N, UI:R) indicates exploitation requires no authentication but does require some form of user interaction, suggesting the attack surface likely involves a front-end booking form or link that a visitor triggers. Depending on available PHP class chains (POP chains) in the WordPress environment, impact can reach full confidentiality, integrity, and availability compromise. No public exploit or CISA KEV listing has been identified at time of analysis.

Unauthenticated PHP object injection in the miniOrange Headless Single Sign On WordPress plugin (versions 1.6 and earlier) lets remote attackers pass attacker-controlled serialized data into a PHP unserialize() call, enabling property-oriented programming (POP) gadget chains that can lead to remote code execution, data theft, or site takeover. The flaw carries a CVSS 9.8 rating with a fully remote, no-authentication, no-interaction vector and was reported by Patchstack; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. Because SSO plugins sit on the authentication path, a successful exploit can compromise the entire WordPress site.

PHP Object Injection in the Car Rental Manager WordPress plugin (versions ≤ 1.3.9, by MagePeople Team) enables authenticated editor-level users to supply malicious serialized PHP payloads that are deserialized without validation, potentially triggering arbitrary code execution on the host server. The CVSS 7.2 score reflects the high-privilege prerequisite (PR:H), yet all three impact dimensions — confidentiality, integrity, and availability — score High, meaning successful exploitation can yield full environment compromise. No public exploit has been identified at time of analysis, and active exploitation has not been confirmed by CISA KEV.

Out-of-bounds memory read in sblim-sfcb's provider-manager IPC message parser allows a local low-privileged attacker to crash the provider-manager process, causing denial of service and potentially leaking limited adjacent memory contents. The vulnerability stems from unsafe deserialization of attacker-controlled IPC messages without adequate boundary validation, affecting sblim-sfcb as shipped across Red Hat Enterprise Linux versions 6 through 10. No public exploit code or active exploitation has been identified at time of analysis, and exploitation is constrained to local system access.

Unauthenticated SQL injection and remote code execution in Ash Framework (ash-project/ash) are achievable by any caller who can reach a keyset-paginated endpoint: the cursor deserializer accepts pre-interned Ash expression structs that bypass query filter guards, yielding SQL injection on AshPostgres deployments or in-process arbitrary code execution on ETS and Simple data layers. All ash versions 1.17.0 through 3.31.2 are exposed across both impact paths. No independently released exploit tooling is known at time of analysis, but the upstream fix commit contains a working proof-of-concept that reproduces the exact forged cursor technique, substantially shortening the path from disclosure to weaponization.

Unsafe deserialization in Apache Airflow 3.0.0 through 3.3.0 allows any DAG author to achieve arbitrary code execution in the Scheduler and API server by placing a crafted value in an operator's executor_config field. The serialization layer reconstructed exception nodes by calling import_string() on an attacker-controlled class name with no allowlist, enabling import and invocation of arbitrary callables such as subprocess.check_output or builtins.eval. Both affected components hold the metadata database credentials and JWT signing secret, making full infrastructure compromise a realistic outcome. No public exploit has been identified at time of analysis, but no non-default configuration is required. This is a distinct sink from CVE-2026-33264, meaning deployments that already patched that earlier advisory remain fully vulnerable and must upgrade again to apache-airflow 3.3.1.

Arbitrary code execution in Fujitsu Research's OneCompression (onecomp) Python library 1.2.0 is triggered when a victim loads a crafted PyTorch checkpoint file via the library's QuantizedModelLoader API, which unconditionally invokes Python's pickle machinery. The root cause is the hardcoded use of torch.load with weights_only=False in load_quantized_model_pt(), allowing an attacker-supplied checkpoint to embed malicious __reduce__ methods that execute arbitrary Python - including OS commands - in the context of the loading process. No public exploit code has been identified at time of analysis, though a patched version (1.2.1) is available on PyPI per the VulnCheck advisory.

Unsafe deserialization in Apache Airflow's XCom REST API allows an authenticated user with XCom write-and-read access to instantiate arbitrary `airflow.*` classes on the API server by smuggling reserved serialization keys inside JSON string literals. The `_check_forbidden_xcom_keys` guard inspected `dict`, `list`, and `tuple` types but did not attempt to JSON-decode `str` values, so a payload like `json.dumps({"__classname__": "airflow.sdk.definitions.connection.Connection"})` passed the write-time check and was later reconstructed into a live Python object when read back via `?deserialize=true`. No public exploit has been identified at time of analysis; vendor-released patch is available in apache-airflow 3.3.1.

Remote code execution and scheduler-process disruption in Apache Airflow 3.3.0 stems from unguarded deserialization of task instance `next_kwargs` during the scheduler's unconditional `awaiting_input` sweep, a code path introduced as part of the 3.3.0 human-in-the-loop task rewrite. Any authenticated DAG author who can influence task state through the task execution API can supply a crafted payload that causes arbitrary module import and object instantiation inside the scheduler process, or terminate the scheduler job entirely. No public exploit has been identified at time of analysis, but a vendor-released patch exists in 3.3.1; deployments that previously patched CVE-2026-58076 are still vulnerable through this distinct code path and must upgrade.
