CVE-2026-59533Network attack vector

Unauthenticated SQL injection through REST searches

Published Jul 27, 2026 · Updated Jul 27, 2026

SQL injection in Relevanssi Light 1.2.2 and earlier allows remote attackers to read WordPress database data through REST searches. The upstream changelog identifies REST searches as the affected path, but neither it nor the CNA record discloses the endpoint, parameter, query, function, or unsafe operation. No authentication or user interaction is required; the published assessment limits impact to data disclosure and limited service interruption.
