CVE-2026-37008

CrewAI before commit fb2323b contains a sandbox escape vulnerability in its Python blocklist mechanism. The blocklist operates at the import-time level by blocking module names, but this does not address the full availability of Python's object graph. For example, calling ctypes.CDLL(None) loads ...

SUSE CVE-2026-84202

ModelScope uses PyYAML's unsafe yaml.Loader to parse model configuration files, allowing arbitrary code execution through Python object construction tags. Attackers can craft malicious model repositories with poisoned configuration files that execute code when loaded by users...

CVE-2026-10036 SpeechBrain < 1.1.1 Arbitrary Code Execution via CKPT.yaml Parsing

SpeechBrain before 1.1.1 contains an arbitrary code execution vulnerability that allows attackers to execute arbitrary code by supplying a crafted CKPT.yaml checkpoint metadata file parsed with PyYAML's unsafe loader during candidate enumeration in Checkpointer.recoverifpossible. Attackers can...

GHSA-36M8-W8QF-G76P SGLang: Unauthenticated RCE via --enable-custom-logit-processor

SGLang's multimodal generation runtime is vulnerable to unauthenticated remote code execution when the --enable-custom-logit-processor option is enabled, as Python objects loaded via dill.loads will be deserialized without validation...

CVE-2026-7818: Deserialization of Untrusted Data

Deserialization of untrusted data CWE-502 in pgAdmin 4 FileBackedSessionManager. The session manager performed unsafe deserialization of session-file contents using Python's standard object-serialization module before performing any HMAC integrity check. Any file dropped into the sessions directo...

CVE-2026-28277: Deserialization of Untrusted Data

LangGraph SQLite Checkpoint is an implementation of LangGraph CheckpointSaver that uses SQLite DB both sync and async, via aiosqlite. In version 1.0.9 and prior, LangGraph checkpointers can load msgpack-encoded checkpoints that reconstruct Python objects during deserialization. If an attacker can...

CVE-2025-65106: Improper Neutralization of Special Elements Used in a Template Engine

LangChain is a framework for building agents and LLM-powered applications. From versions 0.3.79 and prior and 1.0.0 to 1.0.6, a template injection vulnerability exists in LangChain's prompt template system that allows attackers to access Python object internals through template syntax. This...

CVE-2025-64183 OpenEXR has use after free in PyObject_StealAttrString

OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry. In versions 3.2.0 through 3.2.4, 3.3.0 through 3.3.5, and 3.4.0 through 3.4.2, there is a use-after-free in PyObjectStealAttrString of pyOpenEXRold.cpp...

Arbitrary code execution during YAML config parsing in Kubernetes materializer

Summary The Kubernetes materializer entry point feast/sdk/python/feast/infra/computeengines/kubernetes/main.py deserializes /var/feast/featurestore.yaml and /var/feast/materializationconfig.yaml using yaml.load..., Loader=yaml.Loader. Because yaml.Loader eagerly instantiates arbitrary Python...

Liberapay: Unsafe yaml load can lead to remote code execution

The YAML load function can lead to remote code execution vulnerability. The vulnerability allows the construction of arbitrary Python objects from untrusted YAML data, which can be exploited by an attacker...

pgAdmin 8.3 Remote Code Execution Exploit

pgAdmin versions 8.3 and below have a path traversal vulnerability within their session management logic that can allow a pickled file to be loaded from an arbitrary location. This can be used to load a malicious, serialized Python object to execute code within the context of the target...

PyYAML: Arbitrary Code Execution

Background PyYAML is a YAML parser and emitter for Python. Description A vulnerability has been discovered in PyYAML. Please review the CVE identifier referenced below for details. Impact A vulnerability was discovered in the PyYAML library, where it is susceptible to arbitrary code execution whe...

A vulnerability was discovered in the PyYAML library in versions before 5.3.1 where it is susceptible to arbitrary code execution when it processes untrusted YAML files through the full_load method or with the FullLoader loader. Applications that use the library to process untrusted input may be vulnerable to this flaw. An attacker could use this flaw to execute arbitrary code on the system by abusing the python/object/new constructor.
