CVE-2025-67847: Moodle

High severity, CVSS 8.8. EPSS: 0.6% chance of exploitation in the next 30 days.

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.
