Backup Migration, CVE-2025-14944

CVE, Research URL: CVE-2025-14944
Home page URL: Security reports for Backup Migration
Application: Backup Migration
Published on: Apr 07, 2026
Research Description: The Backup Migration plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 2.0.0. This is due to a missing capability check on the 'initializeOfflineAjax' function and lack of proper nonce verification. The endpoint only validates against hardcoded tokens which are publicly exposed in the plugin's JavaScript. This makes it possible for unauthenticated attackers to trigger the backup upload queue processing, potentially causing unexpected backup transfers to configured cloud storage targets and resource exhaustion.
Affected versions: max 2.1.0.
Status: vulnerable
