Description

The BAN Users plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 1.5.3 due to a missing capability check on the 'w3dev_save_ban_user_settings_callback' function. This makes it possible for authenticated attackers, with minimal permissions such as a subscriber, to modify the plugin settings to access the ban and unban functionality and set the role of the unbanned user.

Affected WordPress components

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

  • webxmedia BAN Users — Up to and including 1.5.3
  • webmedia ban_users — Up to and including 1.5.3
