GCVE-110-COMPOSER-2026-026027

The Composer/Packagist package `vladdyslav/klein-up` (version 0.0.4) was flagged as malicious by automated package analysis (3 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.
