A security vulnerability was found in Moodle where confidential information that prevents cross-site request forgery (CSRF) attacks was shared publicly through the site's URL. This vulnerability occurred specifically on two types of pages within the mod_data module: edit and delete pages.

A flaw was found in Moodle. A remote code execution risk was identified in the Moodle LMS Dropbox repository. By default, this was only available to teachers and managers on sites with the Dropbox repository enabled.

A flaw was found in Moodle. A remote code execution risk was identified in the Moodle LMS EQUELLA repository. By default, this was only available to teachers and managers on sites with the EQUELLA repository enabled.

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.

A flaw has been identified in Moodle where insufficient capability checks in certain grade reports allowed users without the necessary permissions to access hidden grades.

A flaw has been identified in Moodle where, on certain sites, unauthenticated users could retrieve sensitive user data—including names, contact information, and hashed passwords—via stack traces returned by specific API calls. Sites where PHP is configured with zend.exception_ignore_args = 'On' or zend.exception_ignore_args = 1 in the relevant php.ini file are NOT affected by this vulnerability. Sites that do not have the zend.exception_ignore_args setting enabled and are using the internal Moodle LMS authentication system are affected by this vulnerability.
