GCVE-110-NPM-2026-016280

Advisory Published

Vulnetix · Advisory published June 22, 2026

The npm package `@mseep/webex-messaging-mcp-server` (version 0.1.0) was flagged as malicious by automated package analysis (4 corroborating detection(s)). Installing it may execute attacker-controlled code via lifecycle scripts or bundled JavaScript. 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.
