Summary

Gokapi vulnerable to Privilege Escalation in File Replace

Details

Summary

An insufficient authorization check in the file replace API allows a user with only list visibility permission (UserPermListOtherUploads) to delete another user's file by abusing the deleteNewFile flag, bypassing the requirement for UserPermDeleteOtherUploads.

Impact

Any authenticated user with PERM_REPLACE (replace own files) and PERM_LIST (view other users' uploads) can delete any other user's file without needing PERM_DELETE.

Severity

4.1 (Medium)
