CVE-2026-3569
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.
Does this matter?
Lower severity and a low EPSS score (0.37%). Track it; it rarely justifies an emergency change on its own.
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.
