A flaw was found in TrailBase. This vulnerability allows an authenticated remote attacker to bypass access controls and access or delete files belonging to other users. By supplying file identifiers associated with other accounts during record creation or update operations without proper ownership validation, an attacker can view unauthorized file contents through their own records or trigger the permanent deletion of another user's files.

Description OSIDB Bzimport 2026-11-10 19:46:59 UTC 
TrailBase 0.28.2 before 0.35.10 contains an insecure direct object reference vulnerability that allows authenticated attackers to manipulate the object-store id metadata within std.FileUpload columns without ownership validation during insert and update operations. Attackers can reference another user's or table's file id in a record they own to read the victim's file bytes through their own record, or trigger permanent deletion of the victim's file by deleting or nulling their own record, while also using a $like filter on the file column to brute-force recover stripped ids character by character.
