Prior to 0.x.y-security-1, substring-based blocklist in plugin-shell's command-safety check could be bypassed by adversarial argument constructions, allowing unauthorized command execution on the host when combined with the companion advisory.

This vulnerability is fixed in 0.x.y-security-1."}], "lastModified": "2026-05-13T17:00:37.097", "sourceIdentifier": "security-advisories@github.com"}
