CVE-2025-23875 Overview
CVE-2025-23875 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Better Protected Pages WordPress plugin by madeglobal. The flaw impacts all versions up to and including 1.0. When successfully exploited, the CSRF condition enables a Stored Cross-Site Scripting (XSS) attack, allowing attackers to persist malicious JavaScript in the application. The vulnerability is classified under CWE-352 (Cross-Site Request Forgery) and requires user interaction to trigger. An authenticated administrator who visits an attacker-controlled page can unknowingly inject malicious payloads that execute in the browser context of subsequent visitors.
Critical Impact
Successful exploitation enables stored XSS through forged administrative requests, leading to session theft, account takeover, and persistent compromise of WordPress sites running the plugin.
Affected Products
- madeglobal Better Protected Pages plugin for WordPress
- All versions through 1.0
- WordPress sites with the better-protected-pages plugin installed and active

Technical Details for CVE-2025-23875
Vulnerability Analysis
The vulnerability combines two web application weaknesses: Cross-Site Request Forgery and Stored Cross-Site Scripting. The plugin's state-changing endpoints lack proper anti-CSRF protections, such as nonce validation. An attacker can craft a malicious HTML page that issues authenticated requests to the WordPress instance when an administrator visits it.
Because the request originates from the victim's authenticated browser session, the application processes it as legitimate. The attacker uses this forged request to submit input that the plugin stores and later renders without proper output encoding, producing a stored XSS payload.
The attack chain requires user interaction, specifically targeting an authenticated administrator. The scope changes to other users because injected scripts execute in the context of anyone subsequently viewing the affected page.
Root Cause
The root cause is the absence of CSRF tokens (WordPress nonces) on plugin endpoints that modify protected page configuration. Combined with insufficient input sanitization and output encoding, the plugin allows attacker-controlled data to be stored and rendered as executable JavaScript.
Attack Vector
The attack vector is network-based and requires a victim with administrative privileges to visit a malicious URL or webpage. The attacker hosts a page containing a hidden form or JavaScript that auto-submits a request to the vulnerable plugin endpoint. Once the request executes, the malicious payload is stored. Any user who later loads the affected page triggers the script in their browser.
The vulnerability mechanism is described in the PatchStack Vulnerability Alert. No public proof-of-concept code is currently available.
Detection Methods for CVE-2025-23875
Indicators of Compromise
- Unexpected <script> tags or JavaScript event handlers stored in plugin-managed page content within the WordPress database.
- HTTP referer headers in web server logs showing administrative actions originating from external, untrusted domains.
- Unusual outbound requests from administrator browsers to attacker-controlled domains following page visits.
- New or modified entries in the wp_options or plugin-specific tables containing encoded JavaScript payloads.
Detection Strategies
- Monitor WordPress administrative endpoints for POST requests lacking valid nonce parameters.
- Inspect plugin-managed content fields for HTML or JavaScript artifacts using database content scanning.
- Correlate administrator session activity with referer headers to identify cross-origin state changes.
- Deploy a Web Application Firewall (WAF) rule to flag requests to better-protected-pages endpoints without the expected nonce.
Monitoring Recommendations
- Enable WordPress audit logging to capture plugin configuration changes and administrator actions.
- Monitor browser-side telemetry for script execution originating from administrative pages.
- Track plugin version inventory across managed WordPress installations and alert on the presence of vulnerable versions.
How to Mitigate CVE-2025-23875
Immediate Actions Required
- Deactivate and remove the Better Protected Pages plugin until a patched release is available.
- Audit existing plugin-managed pages for injected scripts or unauthorized HTML and remove any malicious content.
- Force a password reset and re-authentication for all administrative WordPress accounts.
- Review recent administrator activity logs for evidence of CSRF-driven configuration changes.
Patch Information
As of the latest NVD update on 2026-04-23, no vendor patch beyond version 1.0 has been documented in the available references. Refer to the PatchStack Vulnerability Alert for the latest remediation guidance.
Workarounds
- Restrict access to WordPress administrative URLs by source IP address using web server configuration or a WAF.
- Require administrators to use isolated browser sessions or dedicated browsers when managing WordPress, preventing cross-site request piggybacking.
- Deploy a Content Security Policy (CSP) header that disallows inline scripts to limit the impact of stored XSS payloads.
- Use a security plugin that enforces nonce validation and adds CSRF protection to administrative actions.
# Example: Apache configuration to restrict /wp-admin access by IP
<Directory "/var/www/html/wp-admin">
Require ip 192.0.2.0/24
</Directory>
# Example: Add Content Security Policy header to mitigate XSS
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'"
