CVE-2023-4153BAN Users <= 1.5.3 - Missing Authorization to Authenticated (Subscriber+) Settings Update & Privilege Escalation
High 8.8
In plain English
A high-severity security flaw in BAN Users from webxmedia. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.9% (higher than 59% of all known vulnerabilities).
Official 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.
