Vulnerability Title
Liaison Site Prober <= 1.2.1 - Missing Authorization to Unauthenticated Information Exposure in '/logs' REST API Endpoint
Source: NVD (National Vulnerability Database)
Vulnerability Description
The Liaison Site Prober plugin for WordPress is vulnerable to Information Exposure in all versions up to and including 1.2.1 via the /wp-json/site-prober/v1/logs REST API endpoint. The permissions_read() permission callback unconditionally returns true (via __return_true()) instead of checking for appropriate capabilities. This makes it possible for unauthenticated attackers to retrieve sensitive audit log data including IP addresses, user IDs, usernames, login/logout events, failed login attempts, and detailed activity descriptions.
