CVE-2024-11812 Overview
CVE-2024-11812 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Wtyczka SeoPilot dla WP plugin for WordPress. The flaw exists in all versions up to and including 3.3.091. The root cause is missing or incorrect nonce validation on the SeoPilot_Admin_Options() function. Unauthenticated attackers can update plugin settings and inject malicious web scripts by tricking a site administrator into clicking a crafted link. The issue is categorized under CWE-352: Cross-Site Request Forgery.
Critical Impact
A successful attack allows unauthenticated adversaries to modify plugin settings and inject stored scripts that execute in administrator or visitor browsers, enabling downstream account takeover or SEO poisoning.

Technical Details for CVE-2024-11812
Vulnerability Analysis
The Wtyczka SeoPilot dla WP plugin exposes an administrative options handler, SeoPilot_Admin_Options(), that processes state-changing requests without verifying a WordPress nonce. WordPress nonces are the standard mechanism for confirming that a privileged request originated from an authenticated user interacting with the admin interface. Without this check, the server cannot distinguish between a legitimate administrator action and a forged request delivered from an attacker-controlled page.
Because the vulnerable handler also updates settings that are later rendered in plugin output, an attacker can chain the CSRF into script injection. The injected payload executes in the browser context of anyone loading the affected pages, extending impact beyond configuration tampering. Exploitation requires user interaction, typically a logged-in administrator clicking a malicious link or visiting an attacker-controlled site.
Root Cause
The vulnerability stems from the absence of wp_verify_nonce() or equivalent request-origin validation in the SeoPilot_Admin_Options() function. See the WordPress Plugin Code Reference for the affected code path.
Attack Vector
An attacker hosts a page containing a hidden form or JavaScript that submits a POST request to the WordPress admin endpoint invoking SeoPilot_Admin_Options(). When an authenticated administrator visits the page, their browser sends the request with valid session cookies. The server processes the settings update because no nonce verification takes place. Attacker-controlled script content persists in plugin options and executes when rendered.

Detection Methods for CVE-2024-11812
Indicators of Compromise
- Unexpected modifications to SeoPilot plugin settings in the WordPress wp_options table, particularly options prefixed with seopilot_.
- Presence of <script> tags, event handlers, or external script references within stored SeoPilot configuration values.
- Administrator sessions initiating POST requests to SeoPilot admin endpoints without a matching prior GET request to the settings page.
Detection Strategies
- Review web server access logs for POST requests to wp-admin/admin.php or options.php referencing the SeoPilot plugin with external Referer headers.
- Compare current plugin option values against a known-good baseline to identify unauthorized configuration drift.
- Deploy a Web Application Firewall (WAF) rule that inspects requests to SeoPilot admin actions for missing or invalid _wpnonce parameters.
Monitoring Recommendations
- Enable WordPress audit logging to record administrator setting changes with timestamps, user IDs, and source IP addresses.
- Monitor front-end pages served by the plugin for newly introduced script content using file integrity monitoring or DOM-scanning tools.
- Alert on administrator logins followed within minutes by SeoPilot option changes from unusual referrers.
How to Mitigate CVE-2024-11812
Immediate Actions Required
- Deactivate the Wtyczka SeoPilot dla WP plugin until a patched release is confirmed and installed.
- Audit all SeoPilot plugin settings and remove any unrecognized script content or URLs from stored options.
- Force a password reset for WordPress administrator accounts if evidence of unauthorized setting changes exists.
Patch Information
At the time of publication, no vendor-supplied fixed version is referenced in the NVD entry. Monitor the WordPress plugin repository and the Wordfence advisory for updates and upgrade to the first release above 3.3.091 that introduces nonce validation.
Workarounds
- Restrict access to the WordPress admin interface using IP allowlisting or a VPN to limit CSRF exposure surface.
- Require administrators to use a separate browser or browser profile dedicated to WordPress administration, reducing cross-site attack opportunities.
- Deploy a WAF rule that blocks POST requests to SeoPilot admin actions lacking a valid _wpnonce parameter and a same-origin Referer header.
# Example WAF rule (ModSecurity) to block CSRF against SeoPilot admin actions
