Administrator settings changes via missing nonce validation
Published Nov 9, 2023 · Updated Apr 28, 2026
Cross-site request forgery in CallMeNow 3.0 and earlier allows attackers to alter plugin settings through an administrator session. The lcn_ajax_add_btnsettings and lcn_ajax_add_openinghours AJAX handlers accept state-changing requests without nonce validation. Exploitation requires an authenticated site administrator to open attacker-controlled content, enabling changes to button settings and opening hours.
