AI-suggested

Until a fix is available, restrict access to the get_doctemp view to only authorized users and monitor for suspicious access patterns. Avoid exposing sequential identifiers that can be enumerated. Implement proper authorization checks on the server side.

Description

MrDoc versions through 1.1.1 have a missing authorization vulnerability in the get_doctemp view. Authenticated users can exploit this flaw to read document templates belonging to other users by enumerating the sequential doctemp_id POST parameter. This allows unauthorized access to private template content.
