Arbitrary user denial via missing capability check
Published Sep 9, 2026 · Updated Sep 9, 2026
Missing authorization in Awesome Support 6.3.9 and earlier allows remote authenticated users to deny activation for any account. wpas_do_mr_deny_user() trusts a general nonce and writes mr_user_denied for an attacker-chosen user_id without checking edit_users or edit_user. Subscriber-level access is sufficient to block moderated activation for another user, including an administrator, and send that user a denial email.
