CVE-2025-22703 Overview
CVE-2025-22703 is a Cross-Site Request Forgery (CSRF) vulnerability in the Forge – Front-End Page Builder WordPress plugin developed by manuelvicedo. The flaw enables an attacker to chain a CSRF condition into Stored Cross-Site Scripting (XSS), persisting attacker-controlled JavaScript inside the WordPress site. All versions of the plugin up to and including 1.4.6 are affected. The vulnerability requires user interaction, typically a privileged user visiting an attacker-controlled page while authenticated to WordPress. The issue is tracked under CWE-352: Cross-Site Request Forgery.
Critical Impact
A successful exploit allows an unauthenticated attacker to plant persistent JavaScript in the WordPress site by coercing an authenticated administrator into triggering a forged request, leading to account takeover and content tampering.
Affected Products
- Forge – Front-End Page Builder plugin for WordPress
- All versions from initial release through 1.4.6
- WordPress sites with the plugin installed and an authenticated administrator session

Technical Details for CVE-2025-22703
Vulnerability Analysis
The vulnerability combines two distinct weaknesses into a single exploit chain. The plugin exposes state-changing endpoints that accept requests without verifying a valid WordPress nonce or origin header, satisfying the conditions for CSRF. Those same endpoints then store user-supplied input without proper output encoding or sanitization, producing a Stored XSS sink.
An attacker hosts a malicious page containing an auto-submitting form or fetch() call targeting the vulnerable plugin endpoint. When an authenticated WordPress administrator visits the page, the browser attaches session cookies and the request executes under their privileges. The injected payload is persisted in the site database and later rendered in pages viewed by other users or administrators.
Root Cause
The root cause is the absence of anti-CSRF token validation on plugin actions that modify stored content, combined with insufficient sanitization of accepted parameters. WordPress provides wp_nonce_field() and check_admin_referer() primitives for CSRF protection, but the affected handlers do not invoke them. Input destined for stored content is not filtered with wp_kses_post() or escaped on output with esc_html() or esc_attr().
Attack Vector
Exploitation occurs over the network and requires user interaction from an authenticated victim, typically an administrator. No prior authentication is required from the attacker. Because the injected payload is stored and re-rendered, the impact propagates to every visitor of the affected page, with scope changing from the plugin context to the browser session of each viewer.
The vulnerability mechanism is described in the Patchstack advisory. No public proof-of-concept code has been released.
Detection Methods for CVE-2025-22703
Indicators of Compromise
- Unexpected <script>, <iframe>, or event-handler attributes such as onerror= or onload= appearing in pages or posts created through the Forge page builder
- Outbound requests from administrator browsers to unknown domains shortly after viewing WordPress pages
- New or modified WordPress administrator accounts following an admin session
- POST requests to plugin endpoints originating from a Referer header outside the WordPress admin domain
Detection Strategies
- Audit the wp_posts and plugin option tables for HTML payloads containing script tags, JavaScript URI schemes, or encoded equivalents
- Inspect web server access logs for POST requests to Forge plugin endpoints lacking a valid WordPress admin Referer
- Use a Content Security Policy (CSP) in report-only mode to surface inline script execution from untrusted sources
Monitoring Recommendations
- Forward WordPress and web server logs to a centralized SIEM and alert on plugin-related POST activity outside business hours
- Enable WordPress audit logging to capture content edits, user role changes, and option updates correlated to administrator sessions
- Monitor administrator endpoints for browser-based command-and-control behavior following WordPress access
How to Mitigate CVE-2025-22703
Immediate Actions Required
- Deactivate the Forge – Front-End Page Builder plugin until a patched version is confirmed available from the vendor
- Review all pages and posts created or modified through the plugin for injected HTML or JavaScript and remove malicious content
- Force a password reset for all WordPress administrator accounts and invalidate active sessions
- Restrict administrator access to dedicated browsers or sessions that do not browse untrusted external sites
Patch Information
No fixed version is identified in the published advisory at the time of writing. Versions through 1.4.6 are confirmed vulnerable. Monitor the Patchstack advisory and the WordPress plugin repository for an update beyond 1.4.6 that introduces nonce verification and input sanitization.
Workarounds
- Place the WordPress administration interface behind an IP allowlist or VPN to reduce exposure to drive-by CSRF attacks
- Deploy a web application firewall rule that blocks POST requests to Forge plugin endpoints lacking a same-origin Referer header
- Apply a strict Content Security Policy that disallows inline script execution to limit the impact of stored XSS payloads
- Require administrators to use a separate browser profile dedicated to WordPress administration
# Example WordPress configuration to enforce stricter admin access
# Add to .htaccess in /wp-admin/ to restrict by IP
<RequireAll>
Require ip 203.0.113.0/24
</RequireAll>
# Example CSP response header set via web server
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; frame-ancestors 'self'"
