## How to fix

- Fixed in 2.54.0

## Technical details

The REST API for LMS Quiz Submission lacked adequate authorization checks prior to version 2.54.0, allowing authenticated users to directly create or modify quiz submission records. An attacker authenticated as a student could submit a quiz with perfect scores without verification, or forge submissions attributed to other users via direct API calls. The fix restricts create and write permissions on the LMS Student role for the LMS Quiz Submission doctype.
