GCVE-110-PYPI-2026-016396

Advisory Published

Vulnetix · Advisory published October 17, 2026

The PyPI package `mcp-hangar` (version 2.29.0) was flagged as malicious by automated package analysis (2 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.
