CVE-2026-40798Network attack vector

Database disclosure via unvalidated referer sorting

Published Jun 15, 2026 · Updated Jun 15, 2026

SQL injection in gVectors Team wpForo Forum 3.0.4 and earlier allows remote attackers to read database data via a crafted referer parameter. The topic-list sorting path accepts the request-derived referer value as an order-by selector and incorporates it into SQL without an allowlist. No account or user interaction is required; successful blind queries expose database contents and can cause limited service interruption.
