    CVE-2026-28554

    wpForo Forum 2.4.14 contains a missing authorization vulnerability that allows authenticated subscribers to approve or unapprove any forum post via the wpforo_approve_ajax AJAX handler. Attackers exploit the nonce-only check by submitting a valid nonce with an arbitrary post ID to bypass moderation controls entirely.
