Technical details
An Insecure Direct Object Reference (IDOR) vulnerability exists in ClipBucket v5 due to insufficient authorization checks in the subtitle management components. Specifically, the files `subtitle_popin_upload.php`, `subtitle_edit_core.php`, and `subtitle_delete.php` verify if a user has the general 'edit_video' permission but fail to validate if the user owns the specific video associated with the provided `videoid`. Since the default 'Registered User' level includes the 'edit_video' permission, any authenticated attacker can send crafted POST requests to `/actions/subtitle_edit.php` or `/actions/subtitle_save.php` to manipulate subtitles on any video. This allows for unauthorized uploading of .srt files, renaming of subtitle tracks, or deletion of existing captions. The issue is resolved in version 5.5.3 - #133.
