A flaw was found in Moodle. Due to a missing capability check, a low-privileged authenticated user can trigger the recalculation of grade penalties without holding the required permissions. This issue allows unauthorized users to modify grade penalty records, potentially altering student assessment scores.
Weakness
The web application does not adequately enforce appropriate authorization on all restricted URLs, scripts, or files.
