CVE-2025-32546: All Push Notification for WP CSRF Flaw

CVE-2025-32546 Overview

CVE-2025-32546 is a Cross-Site Request Forgery (CSRF) vulnerability in the "All push notification for WP" WordPress plugin developed by gtlwpdev. This vulnerability can be chained with Reflected Cross-Site Scripting (XSS), allowing attackers to execute malicious scripts in the context of an authenticated user's browser session. The vulnerability affects all versions of the plugin up to and including version 1.5.3.

Critical Impact

Attackers can exploit this CSRF-to-XSS chain to perform unauthorized actions on behalf of authenticated WordPress administrators, potentially leading to account takeover, malicious script injection, and compromise of the entire WordPress installation.

Affected Products

• All push notification for WP plugin versions up to and including 1.5.3
• WordPress installations with the vulnerable plugin installed
• Sites relying on the all-push-notification plugin for push notification functionality

Technical Details for CVE-2025-32546

Vulnerability Analysis

This vulnerability combines two attack vectors: Cross-Site Request Forgery (CSRF) and Reflected Cross-Site Scripting (XSS). The plugin fails to implement proper CSRF token validation on certain form submissions, allowing attackers to craft malicious requests that perform actions on behalf of authenticated users. Additionally, the plugin does not properly sanitize or escape user-supplied input before reflecting it back to the browser, enabling script injection.

The attack requires user interaction—specifically, a victim must be tricked into clicking a malicious link or visiting a crafted webpage while authenticated to the WordPress admin panel. The scope is changed (S:C in CVSS), meaning the vulnerability can affect resources beyond the vulnerable component itself, potentially impacting the entire WordPress site and its visitors.

Root Cause

The root cause of this vulnerability is twofold:

1. Missing CSRF Protection: The plugin does not implement WordPress nonce verification on certain form handlers, allowing external sites to submit requests to the plugin's endpoints.

2. Insufficient Input Sanitization: User-controlled parameters are reflected in the page output without proper escaping, enabling the injection of arbitrary JavaScript code.

These security oversights violate WordPress security best practices, which mandate the use of wp_nonce_field() and wp_verify_nonce() for form protection, along with proper output escaping using functions like esc_html() or esc_attr().

Attack Vector

The attack is network-based and requires user interaction to succeed. An attacker would typically:

1. Craft a malicious HTML page containing a hidden form that targets the vulnerable plugin endpoint
2. Include JavaScript payload in the form parameters that will be reflected without sanitization
3. Entice an authenticated WordPress administrator to visit the malicious page
4. The form auto-submits via JavaScript, sending the request with the victim's session cookies
5. The reflected XSS payload executes in the context of the WordPress admin panel

The attack can be used to create rogue administrator accounts, modify site content, inject persistent malware, or exfiltrate sensitive data from the WordPress dashboard.

Detection Methods for CVE-2025-32546

Indicators of Compromise

• Unexpected administrator accounts created in WordPress
• Suspicious plugin settings modifications without corresponding admin activity
• JavaScript errors or unexpected script execution in browser developer tools when accessing plugin pages
• Unusual outbound requests from the WordPress admin panel to external domains
• Web server access logs showing requests to plugin endpoints with encoded script payloads

Detection Strategies

• Monitor WordPress audit logs for unauthorized configuration changes to the push notification plugin
• Implement Web Application Firewall (WAF) rules to detect and block CSRF attempts and XSS payloads targeting WordPress plugins
• Regularly review installed plugin versions and compare against known vulnerable versions
• Deploy browser-based XSS detection mechanisms to identify reflected script injection attempts

Monitoring Recommendations

• Enable detailed logging for WordPress admin actions, particularly plugin configuration changes
• Configure SIEM alerts for suspicious patterns in WordPress access logs, including encoded JavaScript in URL parameters
• Monitor for unusual network traffic originating from the WordPress server that could indicate successful XSS exploitation
• Implement Content Security Policy (CSP) headers to detect and report XSS attempts

How to Mitigate CVE-2025-32546

Immediate Actions Required

• Update the "All push notification for WP" plugin to a version newer than 1.5.3 if a patched version is available
• If no patch is available, consider temporarily disabling the plugin until a fix is released
• Review WordPress user accounts for any unauthorized administrator accounts
• Audit plugin settings for unauthorized modifications
• Implement additional WAF rules to filter CSRF and XSS attack patterns

Patch Information

Organizations should check the Patchstack WordPress Vulnerability Advisory for the latest patch information and remediation guidance from the plugin developer. Monitor the WordPress plugin repository for updated versions of all-push-notification that address this vulnerability.

Workarounds

• Implement strict Content Security Policy (CSP) headers to mitigate XSS impact by restricting script sources
• Use a Web Application Firewall with rules to detect and block CSRF tokens and XSS payloads
• Limit WordPress admin access to trusted IP addresses only
• Educate administrators about phishing and malicious link attacks that could trigger CSRF exploitation
• Consider using a WordPress security plugin that provides additional CSRF and XSS protection layers

# Add CSP headers in .htaccess for Apache servers
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline';"

# Or in nginx configuration
add_header Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline';";
