CVE-2025-24774: WPCRM WordPress Plugin XSS Vulnerability

CVE-2025-24774 Overview

CVE-2025-24774 is a Reflected Cross-Site Scripting (XSS) vulnerability discovered in the WPCRM - CRM for Contact form CF7 & WooCommerce WordPress plugin developed by mojoomla. This vulnerability arises from improper neutralization of input during web page generation, allowing attackers to inject malicious scripts that execute in the context of a victim's browser session.

Critical Impact

Attackers can craft malicious URLs that, when clicked by authenticated WordPress administrators or users, execute arbitrary JavaScript in their browser. This can lead to session hijacking, credential theft, unauthorized administrative actions, or further compromise of the WordPress installation.

Affected Products

• WPCRM - CRM for Contact form CF7 & WooCommerce plugin versions up to and including 3.2.0
• WordPress installations using the affected WPCRM plugin versions
• Sites integrating WPCRM with Contact Form 7 (CF7) or WooCommerce

Technical Details for CVE-2025-24774

Vulnerability Analysis

This vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation). The WPCRM plugin fails to properly sanitize user-supplied input before reflecting it back in the rendered HTML response. This allows an attacker to inject JavaScript code through URL parameters or form inputs that gets executed when a victim views the crafted page.

Reflected XSS vulnerabilities in WordPress plugins are particularly dangerous because they can be leveraged to target site administrators. When an administrator clicks a malicious link, the attacker's JavaScript runs with full administrative privileges within the WordPress dashboard context.

Root Cause

The root cause of this vulnerability is insufficient input validation and output encoding within the WPCRM plugin. User-controlled data is directly included in the HTML output without proper sanitization or escaping, violating secure coding practices for web applications. The plugin fails to use WordPress's built-in escaping functions such as esc_html(), esc_attr(), or wp_kses() to neutralize potentially malicious input before rendering.

Attack Vector

The attack vector for CVE-2025-24774 involves crafting a malicious URL containing JavaScript payload in one of the vulnerable parameters. The attacker then distributes this URL through phishing emails, social media, or other channels. When a victim clicks the link, the malicious script executes in their browser within the context of the vulnerable WordPress site.

The attack typically follows this pattern: an attacker identifies a vulnerable input field or URL parameter in the WPCRM plugin, crafts a payload containing JavaScript code, and delivers it to potential victims. The reflected nature means the malicious code is not stored on the server but is instead reflected back from the server's response to the victim's request.

Detection Methods for CVE-2025-24774

Indicators of Compromise

• Suspicious URL parameters containing encoded JavaScript payloads (e.g., <script>, javascript:, onerror=)
• Unusual access patterns to WPCRM plugin endpoints with encoded special characters
• Web server logs showing requests with XSS-related patterns in query strings
• Reports from users about unexpected browser behavior or redirects

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common XSS payload patterns
• Implement Content Security Policy (CSP) headers to mitigate script execution from untrusted sources
• Monitor web server access logs for requests containing suspicious URL-encoded characters
• Use browser-based XSS auditors and security extensions for real-time detection

Monitoring Recommendations

• Enable detailed logging for all WordPress plugin activity, particularly WPCRM-related endpoints
• Configure security monitoring tools to alert on anomalous request patterns
• Regularly review access logs for evidence of exploitation attempts
• Implement real-time security monitoring through SentinelOne Singularity platform

How to Mitigate CVE-2025-24774

Immediate Actions Required

• Update the WPCRM plugin to a patched version immediately when available from the developer
• Temporarily disable the WPCRM plugin if no patch is available and the plugin is not critical to operations
• Implement WAF rules to filter XSS payloads targeting known vulnerable parameters
• Review web server logs for evidence of exploitation and investigate any suspicious activity

Patch Information

A security patch should be obtained from the plugin developer mojoomla. Site administrators should monitor the official WordPress plugin repository and the Patchstack Vulnerability Database Entry for updates regarding fixed versions. Until a patch is released, implement the workarounds described below.

Workarounds

• Configure a Web Application Firewall (WAF) to block requests containing XSS payloads
• Implement strict Content Security Policy (CSP) headers to prevent inline script execution
• Restrict access to the WordPress admin dashboard to trusted IP addresses only
• Educate administrators and users about phishing risks and suspicious links
• Consider using a WordPress security plugin that provides virtual patching capabilities

# Example CSP header configuration for Apache .htaccess
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'; img-src 'self' data:; frame-ancestors 'self';"

# Example CSP header for Nginx configuration
add_header Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'; img-src 'self' data:; frame-ancestors 'self';";
