What is CVE-2025-11380?

The Everest Backup plugin for WordPress contains a vulnerability that allows unauthorized users to access sensitive data due to an absence of a capability check on the 'everest_process_status' AJAX action. This flaw affects all versions up to and including 2.3.5, enabling unauthenticated attackers to uncover backup file locations, provided that backups are actively running. This can lead to significant security risks as attackers may subsequently download these files.

Affected Version(s)

Everest Backup – WordPress Cloud Backup, Migration, Restore & Cloning Plugin * <= 2.3.5
