CVE-2026-4118: CWE-352 Cross-Site Request Forgery (CSRF) in tmarek Call To Action Plugin
The Call To Action Plugin plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.1.3. This is due to missing nonce validation in the cbox_options_page() function which handles saving, creating, and deleting plugin settings. The form rendered on the settings page does not include a wp_nonce_field(), and the save handler does not call wp_verify_nonce() or check_admin_referer() before processing settings updates via $wpdb->update(). This makes it possible for unauthenticated attackers to modify plugin settings such as call-to-action box title, content, link URL, image URL, colors, and other configuration options via a forged request, granted they can trick a site administrator into performing an action such as clicking on a link.
AI Analysis
Technical Summary
CVE-2026-4118 is a CSRF vulnerability in the tmarek Call To Action Plugin for WordPress, present in all versions up to 3.1.3. The issue arises because the plugin's settings page form does not include a nonce field, and the save handler does not verify the nonce or check the admin referer before processing updates via $wpdb->update(). This allows unauthenticated attackers to modify plugin settings such as titles, content, URLs, and colors by tricking an administrator into performing an action like clicking a malicious link.
Potential Impact
An attacker can cause an administrator to unknowingly change plugin configuration settings, potentially altering the appearance or behavior of the call-to-action box. This does not directly compromise confidentiality or availability but can lead to unauthorized changes that may affect site integrity or user trust. There is no evidence of exploitation in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, administrators should exercise caution when clicking links and consider restricting access to the plugin settings page to trusted users only. Monitoring for updates from the plugin vendor is recommended.
