TYPO3 CMS - Insecure Deserialization in Core API
TYPO3's cache frontend (VariableFrontend) and persistent key-value store (Registry) deserialized PHP payloads without integrity validation or class restrictions. An attacker with write access to the underlying storage backend (cache store or sys_registry database table) could inject a crafted serialized payload to trigger PHP Object Injection, potentially exploiting a gadget chain to achieve Remote Code Execution or other high-impact effects. Exploiting this vulnerability requires direct local write access to the storage, such as the SQL database or file system. This issue affects TYPO3 CMS versions before 10.4.57, 11.0.0-11.5.50, 12.0.0-12.4.45, 13.0.0-13.4.30 and 14.0.0-14.3.2.
CVE-2026-8365 Alta · 8.8 CWE-502 09/06/2026
Blocksy <= 2.1.41 - Authenticated (Contributor+) PHP Object Injection via Deserialization of Untrusted Data via 'blocksy_meta' REST API Field
The Blocksy theme for WordPress is vulnerable to PHP Object Injection leading to Remote Code Execution via the 'blocksy_meta' REST API field and the V200 database migration in versions up to and including 2.1.35. This is due to insufficient input sanitization in the blocksy_sanitize_post_meta_options() function, which only blocks values containing '<' or '>' and does not prevent serialized PHP object strings from being stored in post meta, combined with the SearchReplacer::run_recursively() function unconditionally deserializing all string values via @unserialize() during migration without restricting allowed classes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject a serialized Blocksy\RaiiPattern object into post meta that, when the V200 migration runs on an upgraded site, is deserialized and triggers RaiiPattern::__destruct(), which executes arbitrary PHP callables via call_user_func().
CVE-2026-41855 Crítica · 9.8 CWE-502 09/06/2026
Desserialização insegura no Spring Framework via conversores Jackson JMS
Em um ambiente JMS não confiável, org.springframework.jms.support.converter.MappingJackson2MessageConverter e org.springframework.jms.support.converter.JacksonJsonMessageConverter permitem a instanciação de classes arbitrárias, o que pode levar a ações não autorizadas por meio da desserialização de classes gadget. Versões afetadas: Spring Framework 7.0.0 até 7.0.7; 6.2.0 até 6.2.18; 6.1.0 até 6.1.27; 5.3.0 até 5.3.48.
CVE-2026-7566 Média · 6.6 CWE-502 06/06/2026
LearnPress – Backup & Migration Tool <= 4.1.4 - Authenticated (Administrator+) PHP Object Injection via WXR XML File Upload
The LearnPress – Backup & Migration Tool plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.1.4 via deserialization of untrusted input . This makes it possible for authenticated attackers, with administrator-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
CVE-2026-7654 Alta · 8.8 CWE-502 05/06/2026
Admin Columns <= 7.0.18 - Authenticated (Contributor+) PHP Object Injection to Remote Code Execution via Custom Field Meta Value
The Admin Columns plugin for WordPress is vulnerable to PHP Object Injection leading to Remote Code Execution in versions up to and including 7.0.18. This is due to the use of `unserialize()` without an `allowed_classes` restriction in the `IdsToCollection::get_ids_from_string()` function, which processes attacker-controlled post meta values without proper validation. This makes it possible for authenticated attackers with Contributor-level access and above to inject a serialized PHP object into a post's custom meta field and trigger arbitrary code execution by exploiting a bundled POP gadget chain, resulting in remote code execution as the web server user.
CVE-2026-25551 Alta · 7.8 CWE-502 04/06/2026
Seagull Software BarTender Deserialization Privilege Escalation via .NET Remoting Service
Seagull Software BarTender 2021 R1 through 12.0.1 contains an insecure deserialization vulnerability that allows low-privileged local users to escalate privileges. The DataServiceSingleton .NET Remoting endpoint is bound to localhost on TCP port 7375 via BtSystem.Service.exe, limiting the attack surface to local access only. The endpoint is configured with BinaryServerFormatterSinkProvider and TypeFilterLevel set to Full. A low-privileged local attacker can send YSoSerial.NET-generated BinaryFormatter payloads to the localhost-bound endpoint to achieve code execution as NT AUTHORITY\\\\SYSTEM. The vulnerability was corrected in BarTender 12.1, released on August 14, 2026. Users should upgrade to BarTender 12.1 or later.
CVE-2026-50076 Crítica · 9.1 CWE-502 04/06/2026
Apache Fory: Java ReplaceResolverSerializer deserialization checks bypass
Deserialization of Untrusted Data in the Java replace-resolve path in Apache Fory fory-core Java SDK before 1.1.0 on Java/JVM platforms allows a remote attacker to bypass class registration, TypeChecker, and DisallowedList checks and invoke classpath-present readResolve/readExternal hooks via crafted Fory serialized data. Users are recommended to upgrade to version 1.1.0 or later, which fixes this issue.
CVE-2026-7888 Alta · 8.4 CWE-502 03/06/2026
Concrete CMS below 9.5.3 is vulnerable to PHP Object Injection via unserialize() calls in the Workflow, Form block, and File/Set components that lack the allowed_classes restriction.
Concrete CMS below 9.5.3 is vulnerable to PHP Object Injection via unserialize() calls in the Workflow, Form block, and File/Set components that lack the allowed_classes restriction. The Form block and File/Set sinks were addressed in 9.5.2; the Workflow component sinks were addressed in 9.5.3. An unauthenticated attacker may trigger arbitrary PHP object instantiation if a malicious serialized payload has been placed in the database. Thanks XananasX7 and Sanjorn Keeratirungsan (dizconnect) for independently reporting the original components, and sh4d0byss for reporting the Workflow component wasn't fixed in 9.5.2. The Concrete CMS security team gave this vulnerability a CVSS v.4.0 score of 8.4 with vector CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/ VC:H/VI:H/VA:H/SC:N/SI:N/SA:N.
CVE-2026-47065 Crítica · 9.8 CWE-502 03/06/2026
Bypass de allow-list de desserialização no Apache MINA (CVE-2026-47065)
ZDRES-232: resolveProxyClass não sobrescrito - bypass do filtro acceptMatchers via java.lang.reflect.Proxy Avaliação: Totalmente tratado. Quando o fluxo serializado contém um TC_PROXYCLASSDESC (o marcador de um java.lang.reflect.Proxy), o readProxyDesc() do ObjectInputStream do JDK é acionado. O JDK então chama a implementação padrão ObjectInputStream.resolveProxyClass(interfaces), que executa Class.forName(intf, false, latestUserDefinedLoader()) para CADA nome de interface e constrói a classe proxy, contornando a lista de classes aceitas. ZDRES-233: Class.forName(name, initialize=true, classLoader) em readClassDescriptor aciona o inicializador estático de classes incluídas na allow-list Avaliação: Totalmente tratado. Para QUALQUER classe na allow-list, desserializar um fluxo que a nomeie aciona o inicializador estático (<clinit>) da classe ANTES de qualquer instância ser construída. Isso significa que um atacante que forneça um nome de classe da allow-list (por exemplo, o desenvolvedor escreveu accept(“com.myapp.*"), e o atacante fornece com.myapp.SomeClass) faz com que o <clinit> de SomeClass seja executado, e muitas classes do mundo real possuem inicializadores estáticos com efeitos colaterais. Ambos os problemas foram corrigidos.
CVE-2026-42211 Alta · 8.1 CWE-502 02/06/2026
React Router's vendored turbo-stream v2 allows arbitrary constructor invocation via TYPE_ERROR deserialization leading to Unauth RCE
React Router is a router for React. In versions 7.0.0 through 7.14.1, when using Framework Mode, a combination of steps could potentially allow unauthorized remote code execution (RCE) through external requests. This attack requires the application code to have an existing prototype pollution vulnerability, which can then be leveraged in a 2-step attack where the second step triggers unauthorized RCE on the remote server. This does not impact applications using Declarative Mode (`<BrowserRouter>`) or Data Mode (`createBrowserRouter/<RouterProvider>`). This is patched in version 7.14.2.
CVE-2026-34993 Alta · 7.3 CWE-502 02/06/2026
AIOHTTP Vulnerable to Deserialization of Untrusted Data
AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.14.0, using ``CookieJar.load()`` with untrusted input may allow arbitrary code execution. Most applications using this function will be doing so with the user's own data, so this is unlikely to affect many applications. Version 3.14.0 patches the issue. If an application does allow attacker controlled files to be loaded, a workaround on older releases would be to sanitize the files before loading.

Execução remota de código não autenticada por desserialização de pickle no AI Tensor Engine for ROCm (AITER)
O AI Tensor Engine for ROCm (AITER) até a versão 0.1.14 contém uma vulnerabilidade de execução remota de código não autenticada na função MessageQueue.recv() dentro de shm_broadcast.py, que permite que atacantes remotos não autenticados executem código arbitrário ao enviar um payload pickle malicioso para um socket ZMQ SUB sem qualquer autenticação, HMAC ou validação de formato. Atacantes que consigam alcançar o endpoint XPUB do writer na rede do cluster, ou fornecer um Handle forjado com um remote_subscribe_addr controlado pelo atacante, podem entregar um payload pickle elaborado que executa código arbitrário simultaneamente como o processo worker de inferência em cada worker leitor remoto.

CVE-2026-10532 Baixa · 2.9 CWE-502 01/06/2026
Logback deserialization whitelist bypass for Proxy objects
Deserialization of untrusted data vulnerability in QOS.CH Sarl logback logback-core (HardenedObjectInputStream (logback-core) modules) allows Object Injection, albeit heavily restricted. More precisely, an attacker able to influence serialized data sent to SimpleSocketServer or SimpleSSLSocketServer can instantiate Proxy objects. Although deserialization is heavily restricted by HardenedObjectInputStream and no practical way to achieve remote code execution or significant privilege escalation has been identified, this issue constitutes a bypass of the intended security restrictions. This issue affects logback: through 1.5.33 inclusive.
