CVE-2026-42682Network attack vector

Unauthenticated privilege escalation during registration

Published Jun 1, 2026 · Updated Jun 1, 2026

Missing authorization in gVectors Team wpForo Forum 3.0.6 and earlier allows remote attackers to escalate privileges during registration. The 3.0.7 changelog identifies usergroup privilege escalation in the registration path, but public sources do not name the endpoint, parameter, or missing check. Unauthenticated reachability is sufficient; a successful registration grants an unauthorized higher-privileged forum role, while its precise permitted actions remain undisclosed.
