CVE-2026-47238Public exploitNetwork attack vector

Subtitle defacement via missing video ownership checks

Published Jun 11, 2026 · Updated Jun 11, 2026

Incorrect authorization in MacWarrior ClipBucket V5 before 5.5.3 - #133 allows remote authenticated users to alter other users' subtitles. The subtitle upload, edit, and delete handlers check only the edit_video permission and trust the caller-supplied videoid without verifying video ownership. The default Registered User role has edit_video enabled, so any self-registered account can add, rename, or delete captions on another user's video, including administrator-owned videos.
