Title
Mooodle: mooodle: information disclosure and script execution via reflected cross-site scripting
Summary
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.
Severity ?
5.4 (Medium)

Title
Moodle: moodle: authentication bypass via lti provider allows suspended users to gain unauthorized access.
Summary
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.
Severity ?
8.1 (High)
CWE

Moodle: moodle: cross-site scripting vulnerability via inadequate input filtering in formula editor
Summary
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.

Title
Moodle: moodle: formula injection allows arbitrary formula execution via unescaped data export
Summary
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.
Severity ?
6.1 (Medium)
