A vulnerability was found in a Moodle TeX filter administrative setting where insufficient sanitization of configuration input could allow command injection. On sites where the TeX filter is enabled and ImageMagick is installed, a maliciously crafted setting value entered by an administrator could result in unintended system command execution. While exploitation requires administrative privileges, successful compromise could affect the entire Moodle server.

A flaw was identified in Moodle’s backup restore functionality where specially crafted backup files were not properly validated during processing. If a malicious backup file is restored, it could lead to unintended execution of server-side code. Since restore capabilities are typically available to privileged users, exploitation requires authenticated access. Successful exploitation could result in full compromise of the Moodle server.
