CVE-2025-67626 Overview
A Cross-Site Request Forgery (CSRF) vulnerability has been identified in the WP SEO Search WordPress plugin developed by Angel Costa. This vulnerability allows attackers to forge malicious requests that execute actions on behalf of authenticated users without their consent. When exploited, attackers can trick administrators or users with elevated privileges into unknowingly performing state-changing operations within the WordPress admin panel.
Critical Impact
Attackers can exploit this CSRF vulnerability to perform unauthorized actions such as modifying plugin settings, changing search configurations, or potentially escalating to further attacks against the WordPress installation when combined with other vulnerabilities.
Affected Products
- WP SEO Search plugin version 1.1 and earlier
- WordPress installations with WP SEO Search plugin installed
- All websites using vulnerable versions of wp-seo-search

Technical Details for CVE-2025-67626
Vulnerability Analysis
This vulnerability is classified under CWE-352 (Cross-Site Request Forgery). The WP SEO Search plugin fails to implement proper CSRF token validation for state-changing operations. Without adequate nonce verification, the plugin accepts and processes requests that lack proof of intentional user action.
In WordPress environments, CSRF protection is typically implemented using nonces (number used once) that validate the authenticity and intent of user requests. The vulnerable plugin versions do not properly generate, validate, or enforce these security tokens on sensitive operations, allowing malicious actors to craft requests that bypass these protections.
Root Cause
The root cause of this vulnerability lies in the absence or improper implementation of WordPress nonce verification functions such as wp_verify_nonce() or check_admin_referer() within the plugin's request handling logic. When form submissions or AJAX requests are processed without validating a unique security token, the application cannot distinguish between legitimate user-initiated requests and forged requests from malicious sources.
Attack Vector
The attack vector involves an attacker crafting a malicious web page or email containing hidden forms or JavaScript that automatically submits requests to the vulnerable WordPress plugin endpoints. When an authenticated administrator visits the attacker-controlled page or clicks a malicious link while logged into their WordPress site, the browser automatically includes session cookies, causing the forged request to be executed with the victim's privileges.
A typical attack scenario involves:
- Attacker identifies a vulnerable endpoint in the WP SEO Search plugin that lacks CSRF protection
- Attacker creates a malicious HTML page containing an auto-submitting form targeting that endpoint
- Attacker tricks an authenticated WordPress administrator into visiting the malicious page
- The victim's browser submits the forged request with valid session credentials
- The plugin processes the request as legitimate, executing the attacker's desired action
Detection Methods for CVE-2025-67626
Indicators of Compromise
- Unexpected changes to WP SEO Search plugin settings without administrator action
- Unusual or unauthorized modifications to search-related configurations in WordPress
- Administrator reports of strange behavior after visiting external links or unknown websites
Detection Strategies
- Review WordPress access logs for unusual POST requests to WP SEO Search plugin endpoints
- Monitor for configuration changes to the plugin that were not initiated through normal administrative workflows
- Implement security plugins that log and alert on plugin settings modifications
Monitoring Recommendations
- Enable comprehensive audit logging for all WordPress plugin configuration changes
- Deploy a Web Application Firewall (WAF) with CSRF detection capabilities
- Implement real-time alerting for modifications to critical plugin settings
How to Mitigate CVE-2025-67626
Immediate Actions Required
- Update the WP SEO Search plugin to the latest version if a patch is available
- Consider disabling the WP SEO Search plugin until a security update is released
- Educate administrators to avoid clicking unknown links while logged into WordPress
- Implement additional CSRF protection through a WordPress security plugin
Patch Information
No official patch information has been confirmed at this time. Website administrators should monitor the Patchstack Vulnerability Report for updates on remediation status and check the WordPress plugin repository for updated versions of WP SEO Search.
Workarounds
- Temporarily disable the WP SEO Search plugin if it is not critical to site functionality
- Implement a Web Application Firewall (WAF) that can detect and block CSRF attack patterns
- Require administrators to use dedicated browsers or incognito mode when performing WordPress administrative tasks
- Consider using WordPress security plugins that add additional CSRF protection layers
# Configuration example
# Disable the vulnerable plugin via WP-CLI until patched
wp plugin deactivate wp-seo-search
# Alternatively, restrict access to WordPress admin area by IP
# Add to .htaccess in wp-admin directory
# <Files "*.php">
# Order Deny,Allow
# Deny from all
# Allow from YOUR.TRUSTED.IP.ADDRESS
# </Files>
