Description
Arkon through 0.9.2 contains a missing authorization vulnerability in list_skill_versions that allows authenticated employees to read other departments' skill version metadata by bypassing the can_access_skill check. Attackers holding the default skill:read permission can request GET /api/skills/{slug}/versions for another department's skill to obtain version numbers, hashes, storage paths and changelogs.
