CVE-2024-8632Network attack vector

Unauthenticated reply disclosure via missing capability checks

Published Oct 1, 2024 · Updated Apr 8, 2026

Missing authorization in KB Support 1.6.6 and earlier allows remote attackers to read any ticket reply and mark any reply as read. The kbs_ajax_load_front_end_replies and kbs_ajax_mark_reply_as_read handlers process unauthenticated AJAX requests without checking a caller capability before fetching replies or updating read state. No account is required, so exposed WordPress sites permit disclosure of ticket conversations and unauthorized changes to reply-read status.
