An SQL injection risk was identified in the module list filter within course search.
A flaw was found in Moodle. An authorization logic flaw, specifically due to incomplete role checks during the badge awarding process, allowed badges to be granted without proper verification. This could enable unauthorized users to obtain badges they are not entitled to, potentially leading to privilege escalation or unauthorized access to certain features.
A flaw was found in Moodle. The analysis request action in the Brickfield tool did not include the necessary token to prevent a Cross-site request forgery (CSRF) risk.
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. 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.
Insufficient sanitizing in the TeX notation filter resulted in an arbitrary file read risk on sites where pdfTeX is available (such as those with TeX Live installed).
The question bank filter required additional sanitizing to prevent a reflected XSS risk.
Description information displayed in the site administration live log required additional sanitizing to prevent a stored XSS risk.
A flaw was found in Moodle. This authentication bypass vulnerability allows suspended users to authenticate through the Learning Tools Interoperability (LTI) Provider. The issue arises from the LTI authentication handlers failing to enforce the user's suspension status, enabling unauthorized access to the system. This can lead to information disclosure or other unauthorized actions by users who should be restricted.
A flaw was found in moodle. This formula injection vulnerability occurs when data fields are exported without proper escaping. A remote attacker could exploit this by providing malicious data that, when exported and opened in a spreadsheet, allows arbitrary formulas to execute. This can lead to compromised data integrity and unintended operations within the spreadsheet.
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.exceptionignoreargs = 'On' or zend.exceptionignoreargs = 1 in the relevant php.ini file are NOT affected by this vulnerability. Sites that do not have the zend.exceptionignoreargs setting enabled and are using the internal Moodle LMS authentication system are affected by this vulnerability.
A brute-force facilitation issue was present in the confirmation email service. Without proper rate limiting, this endpoint could help attackers enumerate or guess credentials with less resistance.
A cross-site scripting (XSS) vulnerability existed due to improper sanitization of AI prompt responses. Attackers could inject HTML or script into pages viewed by other users, potentially leading to session theft or UI manipulation
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 missing check in the Multi-Factor Authentication (MFA) email factor's revoke/cancel action could allow an attacker to revoke a user's only available second authentication factor. This could prevent the user from successfully logging in (denial of service), and also disclose their name in the process via an Insecure Direct Object Reference (IDOR) vulnerability.
Versions affected: 4.5 to 4.5.3, 4.4 to 4.4.7, and 4.3 to 4.3.11 Versions fixed: 4.5.4, 4.4.8, and 4.3.12
Separate Groups mode restrictions were not factored into permission checks before allowing viewing or deletion of responses in Feedback activities.
The drag-and-drop onto image (ddimageortext) question type required additional sanitizing to prevent a stored XSS risk.
A flaw was found in Moodle. An open redirect vulnerability in the OAuth login flow allows a remote attacker to redirect users to attacker-controlled pages after they have successfully authenticated. This occurs due to insufficient validation of redirect parameters, which could lead to phishing attacks or information disclosure.
A flaw was found in Moodle. A remote attacker could exploit a reflected Cross-Site Scripting (XSS) vulnerability in the policy tool return URL. This vulnerability arises from insufficient sanitization of URL parameters, allowing attackers to inject malicious scripts through specially crafted links. Successful exploitation could lead to information disclosure or arbitrary client-side script execution within the user's browser.
A flaw was found in Moodle. The return URL in the policy tool required additional sanitizing to prevent a reflected Cross-site scripting (XSS) risk.
Tags not expected to be visible to a user could still be discovered by them via the tag search page or in the tags block.
Insufficient capability checks made it possible to disable badges a user does not have permission to access.
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 data exposure issue existed where user identifiers were visible in URLs during anonymous assignment submissions, contrary to expected anonymity protections. This could reveal internal IDs to unauthorized viewers.
Additional checks were required to ensure trusttext is applied (when enabled) to glossary entries being restored.
A flaw was found in Moodle. This vulnerability allows unauthorized users to access and view RSS feeds due to insufficient capability checks.
A flaw was found in Moodle. Additional checks were required to prevent users from deleting course sections they did not have permission to modify.
A flaw was found in Moodle. Insufficient capability checks made it possible for a user enrolled in a course to access some details, such as the full name and profile image URL, of other users they did not have permission to access.
A flaw has was found in Moodle where anonymous assignment submissions can be de-anonymized via search, revealing student identities.
A flaw was found in Moodle. Insufficient capability checks in a messaging web service allowed users to view other users' names and online statuses.
