GCVE-110-GEM-2026-000025

Advisory Published

Vulnetix · Advisory published October 17, 2026

The RubyGems gem `pwn` (version 0.5.777) was flagged as malicious by automated package analysis (3 corroborating detection(s)). Installing it may execute attacker-controlled code via the gemspec's native `extensions` build, install hooks, or bundled Ruby/C 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.
