Official Description

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.

Technical Analysis

CVE-2026-26045 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
