MrDoc through 1.1.1 Broken Access Control via manage_doc_share
The advisory, in context
MrDoc through 1.1.1 contains a broken access control vulnerability in the manage_doc_share type 3 branch that allows authenticated users to modify other users' document share settings because updates lack an ownership check. Attackers can compute predictable share tokens from the MD5 of document ID and username to re-enable disabled shares or remove access codes, exposing private documents.
