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. During anonymous assignment submissions, user identifiers were inadvertently exposed in URLs. This data exposure allows unauthorized viewers to see internal user IDs, compromising the intended anonymity and potentially leading to information disclosure.

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 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. This cross-site scripting (XSS) vulnerability, caused by improper sanitization of AI prompt responses, allows attackers to inject malicious HTML or script into web pages. When other users view these compromised pages, their sessions could be stolen, or the user interface could be manipulated.

A flaw was found in mooodle. 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. 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 discovered in Moodle. Additional checks were required to ensure that users can only access cohort data they are authorized to retrieve.
