Summary

XBackBone through 3.8.2 contains a missing authorization vulnerability that allows authenticated users to change other users' upload share codes via the POST /upload/{id}/vanity route.

Recommendation

It is recommended to update XBackBone to a version that fixes this vulnerability and to implement proper access controls for routes that modify share codes.
