Unauthenticated audit-log disclosure via permissive REST callback
Published Apr 24, 2026 · Updated Apr 24, 2026
Information exposure in Liaison Site Prober 1.2.1 and earlier allows remote attackers to read audit logs through its REST API. The permissions_read() callback registers __return_true() for the /logs route instead of checking a WordPress capability. No account or user interaction is required; a network request reveals IP addresses, user identifiers, authentication events, and activity descriptions.
