What is CVE-2019-3852?

A vulnerability exists in Moodle versions prior to 3.6.3 that allows bypassing user capabilities due to the get_with_capability_join and get_users_by_capability functions failing to properly account for context freezing. This oversight may permit unauthorized users to access functionalities they should not be permitted to use, potentially leading to a compromise of the system's security integrity.
