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.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • liaison Liaison Site Prober — Up to and including 1.2.1
