CVE-2026-54499

Stanza is a Stanford NLP Python library for tokenization, sentence segmentation, NER, and parsing of many human languages. Prior to 1.12.2, Stanza model loaders such as stanza.models.common.pretrain.Pretrain.load attempt torch.load..., weightsonly=True but fall back to torch.load...,...

CVE-2026-54499

CVE-2026-54499 affects Stanza prior to 1.12.2, where model loading uses torch.load(..., weights_only=True) and on an attacker-controllable pickle.UnpicklingError falls back to weights_only=False, enabling arbitrary pickle code execution when loading a malicious .pt pretrain/file. The vulnerabilit...

CVE-2026-54499 Stanza: Remote Code Execution via Unsafe Pickle Deserialization in Model Loaders

Stanza is a Stanford NLP Python library for tokenization, sentence segmentation, NER, and parsing of many human languages. Prior to 1.12.2, Stanza model loaders such as stanza.models.common.pretrain.Pretrain.load attempt torch.load..., weightsonly=True but fall back to torch.load...,...

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 ...

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...

Protection Mechanism Failure

Overview fickling is an A static analyzer and interpreter for Python pickle data Affected versions of this package are vulnerable to Protection Mechanism Failure due to shared mutable state in the shortencode function. An attacker can execute arbitrary code by providing a malicious pickle payload...

CVE-2026-14535

In Trail of Bits fickling versions up to and including 0.1.11, the UnsafeImportsML analysis pass unconditionally calls AnalysisContext.shortencodenode on every import node it inspects, regardless of whether the import is flagged as unsafe. This call registers the shortened code representation in...

CVE-2026-14534

Trail of Bits fickling versions up to and including 0.1.10 do not include the Python standard library modules posixsubprocess, site, and atexit in the UNSAFEIMPORTS denylist fickle.py. Because these modules are absent from the denylist, fickling's checksafety function returns LIKELYSAFE with zero...

EUVD-2026-41676

This call registers the shortened code representation in...

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...

EUVD-2026-41675

Trail of Bits fickling versions up to and including 0.1.10 do not include the Python standard library modules posixsubprocess, site, and atexit in the UNSAFEIMPORTS denylist fickle.py. Because these modules are absent from the denylist, fickling's checksafety function returns LIKELYSAFE with zero...

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...

CVE-2026-14534 Fickling check_safety() bypass via unlisted standard library modules (_posixsubprocess, site, atexit)

Trail of Bits fickling versions up to and including 0.1.10 do not include the Python standard library modules posixsubprocess, site, and atexit in the UNSAFEIMPORTS denylist fickle.py. Because these modules are absent from the denylist, fickling's checksafety function returns LIKELYSAFE with zero...
