Moodle: moodle: improper validation in file restore functionality leading to remote code execution_CVE-2026-26045

{
    "lastseen": "",
    "description": "A flaw was identified in Moodle\u2019s 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.",
