MrDoc through 1.1.1 Missing Authorization via Project Document Sort Handlers

MrDoc through 1.1.1 contains a missing authorization vulnerability in the project_doc_sort and manage_project_doc_sort handlers that allows registered users to modify other users' documents by supplying arbitrary document IDs in sort_data. Attackers owning any project can reparent and reorder documents by sequential ID and set their status to draft or removed, hiding published documents.

MrDoc through 1.1.1 Missing Authorization via get_doctemp Template Read

MrDoc through 1.1.1 contains a missing authorization vulnerability in the get_doctemp view that allows authenticated users to read other users' document templates. Attackers can enumerate the sequential doctemp_id POST parameter to retrieve the private template content of every user on the instance.

MrDoc through 1.1.1 Broken Access Control via manage_doc_share

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.

MrDoc through 1.1.1 Missing Authorization via api/import_local_doc/ Endpoint

MrDoc through 1.1.1 contains a missing object-level authorization vulnerability in the ImportLocalDoc API that allows authenticated users to modify other users' documents and projects. Attackers can send PUT requests with arbitrary sort_data document ids to publish private drafts and reparent documents, or POST with arbitrary top_doc ids to inject documents.

MrDoc v0.95 and before is vulnerable to Server-Side Request Forgery (SSRF) in the validate_url function of the app_doc/utils.py file.
