The flaw stems from a prefix-based package match plus an unsafe empty-allow-list default, affecting versions 1.1.0-1.1.17, 1.2.0-1.2.17, and 2.0.0-2.0.5. No public exploit identified at time of analysis, but the CVSS 8.1 rating and CWE-502 classification place this firmly in the high-impact Java deserialization category that has historically yielded remote code execution.

Unsafe deserialization in Spring for Apache Kafka (versions 2.8.0-4.0.5 across multiple branches) allows a malicious Kafka producer to send crafted message headers that cause downstream consumers to instantiate arbitrary JDK types via Jackson. The flaw stems from a prefix-based trusted-packages check in JsonKafkaHeaderMapper and the deprecated DefaultKafkaHeaderMapper, which silently extends trust to every subpackage. No public exploit identified at time of analysis, but the bug class (CWE-502 with Jackson default typing) has a long history of leading to remote code execution in Spring/Java ecosystems.

Insecure deserialization in Spring Security 7.0.0 through 7.0.5 allows an attacker with write access to the saml2_asserting_party_metadata database table to store malicious serialized Java payloads in the verification_credentials or encryption_credentials columns, leading to code execution when the JdbcAssertingPartyMetadataRepository deserializes them. The flaw affects deployments using the JDBC-backed SAML 2.0 asserting-party metadata repository introduced in the Spring Security 7.x line. No public exploit identified at time of analysis and EPSS is very low (0.01%), but CVSS rates impact as High due to full confidentiality, integrity, and availability loss on the application.

Remote code execution in Veeam Backup & Replication enables an authenticated domain user to execute arbitrary code on the Backup Server, with CVSS 4.0 score of 9.4 reflecting high impact across confidentiality, integrity, and availability of both the vulnerable component and downstream systems. The vulnerability is tagged as a deserialization flaw (CWE-502), and while no public exploit is identified at time of analysis, the low attack complexity and only-low-privilege requirement make this a high-priority patching event for any environment running Veeam in a domain-joined configuration.

Cross-site scripting in Microsoft SharePoint Server (2016, 2019, and Subscription Edition) enables low-privileged authenticated attackers to perform spoofing attacks over a network without requiring user interaction. The CVSS vector (AV:N/AC:L/PR:L/UI:N) confirms network-reachable exploitation by any authenticated SharePoint user with no further interaction required from a victim. No public exploit identified at time of analysis and CISA SSVC classifies exploitation status as none, though vendor patches are available for all three affected product lines.

Privilege escalation in Microsoft Office SharePoint allows an authenticated network attacker to elevate privileges by submitting maliciously crafted serialized data that the server deserializes without proper validation. The CVSS 8.8 score reflects high impact across confidentiality, integrity, and availability combined with low attack complexity, though the PR:L requirement means the attacker must already hold at least a low-privileged SharePoint account. No public exploit identified at time of analysis, and the issue is not currently listed in CISA KEV.

Remote code execution in Nuance PowerScribe allows unauthenticated network attackers to run arbitrary code by submitting maliciously crafted serialized objects to the application. The flaw is a CWE-502 untrusted-data deserialization issue carrying a critical CVSS 9.8 score, reported through Microsoft Security Response Center; no public exploit identified at time of analysis. Because PowerScribe is a clinical radiology reporting platform widely deployed in hospital environments, successful exploitation could compromise systems handling protected health information.

PHP Object Injection in TYPO3 CMS's cache frontend (VariableFrontend) and persistent key-value store (Registry) exposes TYPO3 installations to potential Remote Code Execution when an attacker controls write access to the underlying storage layer. The root cause is bare PHP `unserialize()` calls on storage-retrieved data without HMAC integrity validation or class allowlists, meaning attacker-controlled data in the `sys_registry` table or cache backend can trigger deserialization of crafted PHP objects through a gadget chain. No public exploit has been identified at time of analysis and no CISA KEV listing exists; however, the CVSS 4.0 Subsequent impact scores (SC:H/SI:H/SA:H) confirm that successful exploitation yields full system-level impact despite the local access prerequisite.

Authenticated PHP Object Injection in the Blocksy WordPress theme (versions ≤ 2.1.35) allows contributor-level users to escalate to remote code execution by storing a malicious serialized object in post meta that is later deserialized during the V200 database migration. Wordfence-reported flaw chains weak input sanitization in blocksy_sanitize_post_meta_options() with an unconditional @unserialize() call in SearchReplacer::run_recursively(), triggering RaiiPattern::__destruct() to invoke arbitrary callables via call_user_func(). No public exploit identified at time of analysis, but the low-privilege requirement and high impact make this a meaningful priority for sites running upgraded Blocksy installations.

Unsafe JSON deserialization in Spring Framework's JMS message converters (MappingJackson2MessageConverter and JacksonJsonMessageConverter) lets an attacker who controls JMS message content instantiate arbitrary classes, enabling gadget-chain attacks that can escalate to unauthorized actions or remote code execution. It affects Spring Framework 5.3.0-5.3.48, 6.1.0-6.1.27, 6.2.0-6.2.18, and 7.0.0-7.0.7 when applications consume messages from an untrusted JMS source. There is no public exploit identified at time of analysis, and despite a 9.8 CVSS the EPSS probability is only 0.04% and CISA SSVC rates exploitation as 'none'.

Phar deserialization in PhpSpreadsheet (PHPOffice) is reachable on PHP 7.x because the `File::prohibitWrappers` helper added to patch CVE-2026-34084 can be bypassed with a three-slash phar URI such as `phar:///path/file.phar/inner`, where `parse_url` returns false and the wrapper check is skipped. Remote attackers who can supply a file path to `IOFactory::load()` achieve full RCE on PHP 7.x branches (1.x up to 1.30.4) and a phar file-read primitive on PHP 8.x branches up to 5.7.0; publicly available exploit code exists with a working Docker reproducer, though EPSS is only 0.04% (12th percentile).

PHP Object Injection in the LearnPress - Backup & Migration Tool WordPress plugin (versions ≤ 4.1.4, by ThimPress) allows authenticated administrators to supply maliciously crafted serialized data through the plugin's import functionality, triggering unsafe PHP deserialization. The vulnerability itself carries no direct impact in isolation - exploitation is contingent on a separate plugin or theme installing a usable POP (Property-Oriented Programming) chain on the same site, at which point an attacker can escalate to arbitrary file deletion, sensitive data retrieval, or remote code execution. No public exploit code and no CISA KEV listing have been identified at time of analysis, and the CVSS score of 6.6 (High complexity, High privileges required) reflects the constrained real-world conditions.

Authenticated remote code execution in the Admin Columns WordPress plugin (versions through 7.0.18) allows Contributor-level users to inject serialized PHP objects via post meta and trigger a bundled POP gadget chain through the Laravel SerializableClosure component. Reported by Wordfence with CVSS 8.8, no public exploit identified at time of analysis, though the low privilege barrier and bundled gadget chain make weaponization straightforward for any researcher with plugin access.

Local privilege escalation in Seagull Software BarTender 2021 R1 through 12.0.1 allows any low-privileged user on the host to gain SYSTEM execution by sending a crafted BinaryFormatter payload to a localhost-bound .NET Remoting endpoint. Publicly available exploit code exists (a YSoSerial.NET-based PoC is published as a GitHub gist), and the issue carries a CVSS 4.0 base score of 8.5 with high confidentiality, integrity, and availability impact. No CISA KEV listing is present, so exploitation is opportunistic rather than confirmed in-the-wild.

Unsafe deserialization in Apache Fory fory-core Java SDK versions prior to 1.1.0 allows remote attackers to bypass the framework's class registration, TypeChecker, and DisallowedList security controls on Java/JVM platforms. By crafting malicious Fory-serialized payloads that exercise the replace-resolve path, an attacker can invoke arbitrary readResolve/readExternal hooks on any class present on the classpath, enabling gadget-chain abuse without authentication. No public exploit identified at time of analysis, but the CVSS 9.1 score and CWE-502 classification reflect the high impact typical of Java deserialization sinks.

PHP object injection in Concrete CMS versions below 9.5.2 allows authenticated high-privileged attackers to trigger arbitrary PHP object instantiation through unsafe unserialize() calls in the Workflow, Form block, and File/Set components. The vulnerability requires a malicious serialized payload to be placed in the database beforehand, and no public exploit identified at time of analysis. The vendor scored this 8.4 (CVSS 4.0), and CISA SSVC indicates no observed exploitation but total technical impact if successfully chained.

Unsafe Java deserialization in Apache MINA's ObjectSerializationDecoder allows remote unauthenticated attackers to bypass the acceptMatchers class allow-list and achieve arbitrary code execution. Two distinct flaws are addressed: a TC_PROXYCLASSDESC handling gap where resolveProxyClass is not overridden (permitting java.lang.reflect.Proxy instantiation outside the allow-list), and a Class.forName invocation in readClassDescriptor that triggers static initializers of allow-listed classes before any instance check. No public exploit identified at time of analysis, but the CVSS 9.8 rating and well-known deserialization attack patterns make this a high-priority issue for any application exposing MINA's object serialization codec.

Arbitrary code execution in the aiohttp Python framework (versions prior to 3.14.0) arises when CookieJar.load() deserializes an attacker-controlled file, classed as CWE-502 unsafe deserialization. An attacker who can plant or substitute the persisted cookie file and induce the application to load it gains code execution in the host process. There is no public exploit identified at time of analysis, EPSS is very low (0.06%), and CISA SSVC rates exploitation as none - consistent with the library's own note that the function is normally used on the user's own trusted data.

Remote code execution in React Router 7.0.0 through 7.14.1 affects applications running in Framework Mode by chaining an application-level prototype pollution flaw with router internals to achieve unauthenticated RCE on the server. Applications using Declarative Mode (BrowserRouter) or Data Mode (createBrowserRouter/RouterProvider) are unaffected. No public exploit identified at time of analysis; CVSS 8.1 reflects high impact tempered by high attack complexity due to the prerequisite prototype pollution gadget.

Local code execution in NVIDIA NVTabular allows a low-privileged attacker to abuse insecure deserialization of untrusted data, potentially leading to arbitrary code execution, data tampering, and information disclosure on the host running the library. The flaw carries a CVSS 7.8 (High) rating with confidentiality, integrity, and availability all marked High, and currently no public exploit identified at time of analysis. NVTabular is a tabular feature-engineering library used in recommender-system pipelines, so the practical blast radius is data-science workstations and ML training nodes.

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.
