CVE-2026-12698Network attack vector

Account-state manipulation via profile field mass assignment

Published Aug 4, 2026 · Updated Aug 4, 2026

Improper access control in gVectors Team wpForo Forum before 3.1.3 allows remote authenticated users to alter their account state and reputation. The profile update handler accepts member-supplied values for administrator-controlled status and reputation fields instead of allowlisting member-editable fields. Subscriber-level access is sufficient to self-activate a pending or banned account and forge the forum reputation score.
