GCVE-110-PYPI-2026-016242

Advisory Published

Vulnetix · Advisory published September 3, 2026

The PyPI package `langchain-anthropic` (version 1.7.1) was flagged as malicious by automated package analysis (1 corroborating detection(s)). Installing it may execute attacker-controlled code via setup.py or bundled Python sources. Verdict path: evidence — for ownership-only paths (owner-known-bad / multi-identity) the change of ownership is a compounding indicator the engine correlated with other signals, not standalone proof. This verdict is produced by static analysis and is subject to human review.
