Description

The BackWPup – WordPress Backup & Restore Plugin plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'backwpup_working' AJAX action in all versions up to, and including, 5.5.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to retrieve access to a back-up's filename while a backup is running. This information has little value on it's own, but could be used to aid in a brute force attack to retrieve back-up contents in limited environments (i.e. NGINX).

Affected WordPress components

  • BackWPup – WordPress Backup & Restore Plugin Plugin · backwpup
    Confirmed match Active
    Up to and including 5.5.0
    View on WordPress.org

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • wp_media BackWPup – WordPress Backup & Restore Plugin — Up to and including 5.5.0
