CVE-2025-25092: All Push Notification for WP XSS Flaw

CVE-2025-25092 Overview

CVE-2025-25092 is a Reflected Cross-Site Scripting (XSS) vulnerability discovered in the "All push notification for WP" WordPress plugin developed by gtlwpdev. The vulnerability stems from improper neutralization of user-supplied input during web page generation, allowing attackers to inject malicious scripts that execute in the context of a victim's browser session.

This Reflected XSS vulnerability enables attackers to craft malicious URLs that, when clicked by authenticated WordPress administrators or users, execute arbitrary JavaScript code in their browsers. This can lead to session hijacking, credential theft, or unauthorized actions performed on behalf of the victim.

Critical Impact

Attackers can exploit this vulnerability to steal session cookies, redirect users to malicious sites, or perform unauthorized administrative actions on WordPress installations running the vulnerable plugin.

Affected Products

• All push notification for WP plugin versions through 1.5.3
• WordPress installations with the all-push-notification plugin installed

Technical Details for CVE-2025-25092

Vulnerability Analysis

This vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation), commonly known as Cross-Site Scripting. The "All push notification for WP" plugin fails to properly sanitize and escape user-controlled input before reflecting it back in the HTTP response, allowing malicious script injection.

Reflected XSS vulnerabilities in WordPress plugins are particularly dangerous because they often target administrative users who have elevated privileges. When an administrator clicks on a crafted malicious link, the injected JavaScript executes within the context of their authenticated session, potentially allowing attackers to perform administrative actions or extract sensitive information.

Root Cause

The root cause of this vulnerability lies in inadequate input validation and output encoding within the plugin's codebase. User-supplied parameters are reflected in the HTML output without proper sanitization using WordPress security functions such as esc_html(), esc_attr(), or wp_kses(). This allows specially crafted input containing JavaScript payloads to be rendered and executed by the victim's browser.

Attack Vector

The attack vector for this Reflected XSS vulnerability involves social engineering to trick users into clicking on malicious URLs. An attacker would construct a URL containing a malicious JavaScript payload within a vulnerable parameter. When a victim navigates to this URL, the malicious script executes in their browser context.

The vulnerability can be exploited to inject JavaScript that steals session cookies, captures keystrokes, modifies page content, or redirects users to phishing sites. Since this is a reflected attack, the malicious payload is delivered through the URL itself rather than being stored on the server.

Detection Methods for CVE-2025-25092

Indicators of Compromise

• Suspicious URLs containing encoded JavaScript payloads directed at your WordPress installation
• Unusual outbound requests from administrator browsers to unknown external domains
• Unexpected modifications to WordPress settings or user accounts following link clicks
• Web server logs showing requests with JavaScript-like content in query parameters targeting the plugin endpoints

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block XSS payloads in URL parameters
• Monitor web server access logs for requests containing suspicious encoded characters or script tags
• Deploy browser-based security extensions that warn users about potentially malicious URLs
• Utilize SentinelOne Singularity to detect post-exploitation activities resulting from successful XSS attacks

Monitoring Recommendations

• Enable WordPress audit logging to track administrative actions and detect unauthorized changes
• Monitor network traffic for unusual data exfiltration patterns from client browsers
• Review Content Security Policy (CSP) violation reports for script injection attempts
• Implement real-time alerting for authentication events from unexpected IP addresses

How to Mitigate CVE-2025-25092

Immediate Actions Required

• Deactivate and remove the "All push notification for WP" plugin if it is not essential
• If the plugin is required, restrict administrative access to trusted IP addresses only
• Implement a Content Security Policy (CSP) header to mitigate XSS exploitation
• Educate administrators about the risks of clicking untrusted links

Patch Information

At the time of publication, versions through 1.5.3 of the "All push notification for WP" plugin are confirmed vulnerable. Website administrators should monitor the plugin's official page and the Patchstack security database for updates and apply patches as soon as they become available.

Workarounds

• Remove or deactivate the vulnerable plugin until a security patch is released
• Implement strict Content Security Policy headers to prevent inline script execution
• Use a WordPress security plugin that provides XSS protection and input filtering
• Restrict access to the WordPress admin area using IP whitelisting or VPN requirements

# Add Content Security Policy header to mitigate XSS in Apache
# Add to .htaccess file
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none';"
