CVE-2026-120427 Details
Description
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.
A missing authorization vulnerability has been identified in MrDoc versions through 1.1.1. The issue resides in the 'get_doctemp' view, where authenticated users can access other users' private document templates. This vulnerability allows for unauthorized reading of template content by exploiting the absence of owner checks in the retrieval process. The 'doctemp_id' POST parameter can be sequentially enumerated to access the private templates of all users on the platform.
The vulnerability has been fixed in the MrDoc v1.1.1 release by adding the necessary owner checks to the 'get_doctemp' view. Users should update to this version to address the issue.
