BAN Users <= 1.5.3 - Missing Authorization to Authenticated (Subscriber+) Settings Update & Privilege Escalation

BAN Users <= 1.5.3 - Missing Authorization to Authenticated (Subscriber+) Settings Update & Privilege Escalation

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.
Mögliche Gegenmaßnahme
BAN Users: No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
