GCVE-110-CARGO-2026-003725

Advisory Published

Vulnetix · Advisory published June 30, 2026

The crates.io crate `mcp-loco` (version 0.1.2) was flagged as malicious by automated package analysis (2 corroborating detection(s)). Installing it may execute attacker-controlled code via its build.rs build script or bundled Rust source. 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.
