BISHENG through 3.0.0-beta4 contains an insecure direct object reference vulnerability that allows authenticated low-privileged users to read other users' parsed documents by supplying arbitrary file_id values. Attackers can enumerate sequential file ids against GET /api/v1/knowledge/file_bbox to retrieve extracted page text from other users' and tenants' knowledge bases.
