CVE-2025-22300 Overview
CVE-2025-22300 is a Cross-Site Request Forgery (CSRF) vulnerability in the PixelYourSite WordPress plugin, tracked under [CWE-352]. The flaw affects PixelYourSite – Your smart PIXEL (TAG) Manager from unspecified earlier versions through 10.0.1.2. Attackers can trick authenticated users into submitting forged requests that alter plugin state without their consent. Exploitation requires user interaction, such as clicking a malicious link while logged into WordPress. The vulnerability carries a CVSS 3.1 score of 5.4, reflecting limited integrity and availability impact without confidentiality loss.
Critical Impact
Attackers can forge authenticated requests against WordPress sites running vulnerable PixelYourSite versions, enabling unauthorized configuration changes to tracking pixel and tag manager settings.
Affected Products
- PixelYourSite – Your smart PIXEL (TAG) Manager plugin for WordPress
- All versions up to and including 10.0.1.2
- WordPress sites where the plugin is installed and activated

Technical Details for CVE-2025-22300
Vulnerability Analysis
The vulnerability stems from missing or improperly validated anti-CSRF tokens in the PixelYourSite plugin. WordPress provides a nonce mechanism through wp_nonce_field() and check_admin_referer() to prevent request forgery. When plugin code processes state-changing requests without verifying these nonces, attackers can craft external pages that trigger privileged actions using a victim's active session.
The attack targets authenticated WordPress users, typically administrators managing the plugin. A victim who visits an attacker-controlled page while logged into WordPress unknowingly submits requests to the vulnerable endpoints. The browser attaches the session cookie automatically, satisfying WordPress authentication checks.
Exploitation does not require credentials or elevated privileges from the attacker. The attack complexity is low and can be delivered through phishing, malicious advertising, or compromised third-party sites. The EPSS score of 0.172% suggests limited near-term exploitation activity in the wild.
Root Cause
The root cause is the absence of proper CSRF token validation on state-changing endpoints exposed by the plugin. Handlers accept POST or GET requests based solely on session authentication, ignoring origin verification. This design contradicts the WordPress security guidance requiring nonce checks on admin actions.
Attack Vector
The attack vector is network-based over HTTP or HTTPS. An attacker hosts a page containing an auto-submitting form or image tag targeting the vulnerable plugin endpoint. When an authenticated WordPress administrator visits the page, the browser submits the forged request. The plugin executes the requested action under the victim's identity, altering tracking pixel configurations or related plugin data.

Detection Methods for CVE-2025-22300
Indicators of Compromise
- Unexpected modifications to PixelYourSite plugin settings, including pixel IDs, event configurations, or tracking parameters
- HTTP referer headers pointing to external domains on requests targeting plugin admin endpoints
- Administrator session activity originating from unusual geolocations or user agents shortly before configuration changes
- WordPress audit log entries showing plugin option updates without corresponding admin console navigation
Detection Strategies
- Deploy a WordPress security plugin that logs all option changes and administrative actions with source IP and referer data
- Monitor web server access logs for POST requests to PixelYourSite endpoints with external or missing referer headers
- Implement Content Security Policy (CSP) headers and analyze CSP violation reports for unexpected cross-origin form submissions
- Alert on modifications to wp_options entries associated with the PixelYourSite plugin outside change windows
Monitoring Recommendations
- Continuously review WordPress admin activity logs for configuration changes correlated with off-site referrers
- Track plugin version inventory across all WordPress sites and flag installations running 10.0.1.2 or earlier
- Monitor outbound traffic from tracking pixels for redirection to unrecognized analytics or advertising endpoints
How to Mitigate CVE-2025-22300
Immediate Actions Required
- Update the PixelYourSite plugin to the latest version above 10.0.1.2 as soon as the vendor releases a patched build
- Audit administrator accounts and enforce multi-factor authentication (MFA) on all privileged WordPress users
- Review PixelYourSite plugin settings for unauthorized modifications and restore known-good configurations from backup
- Instruct administrators to log out of WordPress before browsing untrusted sites
Patch Information
Consult the Patchstack Vulnerability Advisory for the current patched version and vendor update guidance. Apply the fixed release through the WordPress plugin manager or WP-CLI once available.
Workarounds
- Deactivate the PixelYourSite plugin until a patched version is installed if immediate tracking functionality is not required
- Restrict /wp-admin/ access by IP allowlist through the web server or a web application firewall (WAF)
- Deploy a WAF rule that blocks POST requests to PixelYourSite admin endpoints when the referer header does not match the site origin
- Use browser session isolation for administrative WordPress access to prevent cross-site request execution
# Example: update the plugin via WP-CLI once a patched version is available
wp plugin update pixelyoursite --version=<patched-version>
# Example: temporarily deactivate the plugin
wp plugin deactivate pixelyoursite
