A flaw was found in Moodle. A remote attacker could exploit a lack of proper rate limiting in the confirmation email service. This vulnerability allows attackers to more easily enumerate or guess user credentials, facilitating brute-force attacks against user accounts.

A flaw was found in moodle. This vulnerability, known as Cross-Site Scripting (XSS), occurs due to insufficient checks on user-provided data in the formula editor's arithmetic expression fields. A remote attacker could inject malicious code into these fields. When other users view these expressions, the malicious code would execute in their web browsers, potentially compromising their data or leading to unauthorized actions.

A flaw was found in Moodle. An attacker with access to the restore interface could trigger server-side execution of arbitrary code. This is due to insufficient validation of restore input, which leads to unintended interpretation by core restore routines. Successful exploitation could result in a full compromise of the Moodle application.

Moodle 3.10.3 contains a persistent cross-site scripting vulnerability in the calendar event subtitle field that allows attackers to inject malicious scripts. Attackers can craft a calendar event with malicious JavaScript in the subtitle track label to execute arbitrary code when users view the event.

A flaw in the cohort search web service allowed users with permissions in lower contexts to access cohort information from the system context, revealing restricted administrative data.

A flaw was found in the course overview output function where user access permissions were not fully enforced. This could allow unauthorized users to view information about courses they should not have access to, potentially exposing limited course details.

Moodle failed to verify enrolment status correctly when sending quiz notifications. As a result, suspended or inactive users might receive quiz-related messages, leaking limited course information.

An error-handling issue in the Moodle router (r.php) could cause the application to display internal directory listings when specific HTTP headers were not properly configured.

Moodle’s mobile and web service authentication endpoints did not sufficiently restrict repeated password attempts, making them susceptible to brute-force attacks.

An issue in Moodle’s timed assignment feature allowed students to bypass the time restriction, potentially giving them more time than allowed to complete an assessment.
