Unauthenticated site takeover via unchecked option updates
Published Jun 7, 2023 · Updated Dec 28, 2024
Missing authorization in WPKube Social Sharing Plugin – Kiwi 2.1.0 through 2.1.2 allows remote attackers to read and write site options. The unauthenticated AJAX handlers pass attacker-controlled option groups, keys, and values to WordPress option reads and updates without a capability check. No account is required, and changing registration, default-role, or site URL settings enables administrator creation or traffic redirection.
