CVE-2026-19704Network attack vectorHinoki check available

Comment disclosure via unvalidated AJAX query value

Published Sep 2, 2026 · Updated Sep 2, 2026

SQL injection in gVectors Team wpDiscuz before 7.6.66 allows remote attackers to read restricted comments through AJAX comment loading. The AJAX loader inserts an unvalidated request value into a database query as SQL grammar instead of binding it as data. No authentication is required; disclosure is limited to pending, spam, trashed, private-post, and draft-post comments rather than arbitrary database data.
