CVE-2026-12721Public exploitNetwork attack vector

Unauthenticated database disclosure via relation SQL injection

Published Jul 31, 2026 · Updated Jul 31, 2026

SQL injection in Themeum Kirki before 6.0.13 allows remote attackers to read WordPress database data through unauthenticated REST requests. The collection endpoint uses each dynamic-content filter's relation value as SQL clause glue without sanitizing or escaping it, so injected operators and subqueries execute. No account or user interaction is required; a published time-based oracle extracts administrator names, password hashes, and authentication keys.
