WordPress Plugin Vulnerabilities

WP Cerber < 9.3.3 - User Enumeration Bypass via Rest API

Description

The plugin does not properly block access to the REST API users endpoint when the blog is in a subdirectory, which could allow attackers to bypass the restriction in place and list users

Proof of Concept

When the "Block access to users' data via REST API" settings is enabled (wp-admin/admin.php?page=cerber-security&tab=hardening)

Affects Plugins

Fixed in 9.3.3
