A security vulnerability was discovered in Moodle that allows students to enroll themselves in courses without completing all the necessary safety checks. Specifically, users can sign up for courses prematurely, even if they haven't finished two-step verification processes.
On certain Moodle sites, it was possible to retrieve user data, including names, contact information, and hashed passwords, via a stack trace returned by an API call. Sites with PHP configured with zend.exceptionignoreargs = 1 in the php.ini file are not affected by this vulnerability.
Versions affected: 4.5 to 4.5.2 Versions fixed: 4.5.3
