CVE-2026-14535

A flaw was found in the fickling library, versions up to and including 0.1.11. A logic error in the security analysis passes allows an attacker to bypass intended safety checks during pickle deserialization. This vulnerability enables the invocation of arbitrary standard library modules, leading ...

CVE-2026-14534

A flaw was found in the fickling library, which is designed to safely handle Python pickle data. The library's security checks in versions up to and including 0.1.10 fail to properly identify and block certain dangerous Python standard library modules during deserialization. This oversight allows...

PYSEC-2026-1514 LangChain pickle deserialization of untrusted data

A vulnerability in the FAISS.deserializefrombytes function of langchain-ai/langchain allows for pickle deserialization of untrusted data. This can lead to the execution of arbitrary commands via the os.system function. The issue affects versions prior to 0.2.4...

PYSEC-2026-1978 Transformers Deserialization of Untrusted Data vulnerability

The huggingface/transformers library is vulnerable to arbitrary code execution through deserialization of untrusted data within the loadrepocheckpoint function of the TFPreTrainedModel class. Attackers can execute arbitrary code and commands by crafting a malicious serialized payload, exploiting...

CVE-2026-14535

Summary: CVE-2026-14535 affects Trail of Bits fickling up to version 0.1.11. A logic error in the UnsafeImportsML and MLAllowlist passes causes shared mutable state (AnalysisContext.reported_shortened_code) to poison deduplication, rendering MLAllowlist dead code and allowing certain pickle paylo...

CVE-2026-14534

The CVE-2026-14534 issue affects the Python package fickling, up to version 0.1.10. The root cause is that the UNSAFE_IMPORTS denylist omits three standard library modules — _posixsubprocess, site, and atexit — causing check_safety() to return LIKELY_SAFE and allowing pickle payloads to deseriali...
