GCVE-110-COMPOSER-2026-000145

Advisory Published

Vulnetix · Advisory published October 6, 2026

The Composer/Packagist package `cecil/cecil` (version 9.8.0) was flagged as malicious by automated package analysis (4 corroborating detection(s)). Installing it may execute attacker-controlled code via composer.json lifecycle scripts or bundled PHP. 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.
