Technical details
The list_skill_versions endpoint in Arkon's skills router fails to enforce the can_access_skill authorization check before returning version metadata. An authenticated user with the default skill:read permission can bypass departmental access controls by directly requesting GET /api/skills/{slug}/versions for another department's skill, obtaining version numbers, hashes, storage paths, and changelogs. The vulnerability exists in versions up to 0.9.2.
