GCVE-110-GEM-2026-000991

Advisory Published

Vulnetix · Advisory published November 2, 2026

The RubyGems gem `shared_tools` (version 0.7.1) was flagged as malicious by automated package analysis (2 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.
