What is CVE-2026-3569?
CVE-2026-3569 is a medium-severity missing authorization vulnerability in Liaison Site Prober, published on 24 Apr 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
