CVE-2026-2468Network attack vector

Unauthenticated SQL injection via unescaped access cookie

Published Mar 21, 2026 · Updated Mar 21, 2026

SQL injection in Quentn WP 1.2.12 and earlier allows remote attackers to read sensitive database data via the qntn_wp_access cookie. The get_user_access() method inserts the user-supplied cookie value into an existing SQL query without sufficient escaping or parameterization. No authentication or user interaction is required; a crafted HTTP cookie appends SQL and exposes database contents, with no reported write impact.
