CVE-2025-62074: WPMobile.App wpappninja XSS Vulnerability

CVE-2025-62074 Overview

CVE-2025-62074 is a Cross-Site Scripting (XSS) vulnerability affecting the WPMobile.App WordPress plugin (wpappninja) developed by Amauri. This vulnerability stems from improper neutralization of input during web page generation, allowing attackers to inject malicious scripts into web pages viewed by other users. The vulnerability affects all versions of WPMobile.App through version 11.71.

Critical Impact

Attackers can execute arbitrary JavaScript in victim browsers, potentially leading to session hijacking, credential theft, defacement, or malware distribution through affected WordPress sites.

Affected Products

• WPMobile.App (wpappninja) versions up to and including 11.71
• WordPress installations running vulnerable WPMobile.App plugin versions
• Sites using WPMobile.App for mobile application functionality

Technical Details for CVE-2025-62074

Vulnerability Analysis

This Cross-Site Scripting vulnerability exists within the WPMobile.App WordPress plugin due to insufficient input sanitization. The plugin fails to properly neutralize user-supplied input before incorporating it into dynamically generated web pages. This allows an attacker to craft malicious input containing JavaScript code that executes in the context of a victim's browser session when they view the affected page.

The vulnerability requires user interaction to exploit successfully, as victims must navigate to a page containing the injected payload. However, due to the network-accessible nature of WordPress sites and the changed scope of impact, successful exploitation can affect resources beyond the vulnerable component itself.

Root Cause

The root cause of CVE-2025-62074 is the failure to implement proper input validation and output encoding within the WPMobile.App plugin. User-controllable data is passed to the web page generation process without adequate sanitization, violating the principle of treating all user input as untrusted. This lack of neutralization allows specially crafted input containing HTML and JavaScript to be rendered as executable code rather than being treated as plain text.

Attack Vector

The attack vector for this vulnerability is network-based, requiring no authentication but necessitating user interaction. An attacker can exploit this vulnerability by:

1. Identifying input fields or parameters processed by the WPMobile.App plugin
2. Crafting a malicious payload containing JavaScript code
3. Delivering the payload to victims through social engineering, malicious links, or by injecting it into stored content
4. When a victim's browser processes the payload, the malicious script executes with the privileges of the victim's session

The vulnerability exploitation typically involves injecting script tags or event handlers that execute arbitrary JavaScript when the malicious content is rendered in a victim's browser.

Detection Methods for CVE-2025-62074

Indicators of Compromise

• Unusual JavaScript code or <script> tags appearing in plugin-generated content or database entries
• Unexpected HTTP requests to external domains originating from the WordPress site
• User reports of strange behavior, pop-ups, or redirects when visiting the site
• Log entries showing requests with encoded script payloads in URL parameters or form submissions

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect common XSS patterns in requests and responses
• Monitor WordPress audit logs for suspicious content modifications or plugin configuration changes
• Deploy browser-based security headers such as Content-Security-Policy to mitigate script execution
• Conduct regular security scans of the WordPress installation to identify vulnerable plugin versions

Monitoring Recommendations

• Enable detailed logging for the WPMobile.App plugin and review logs for anomalous activity
• Monitor outbound network connections from the web server for unexpected external communication
• Set up alerts for modifications to plugin files or database tables associated with WPMobile.App
• Implement client-side monitoring to detect unauthorized script execution in user browsers

How to Mitigate CVE-2025-62074

Immediate Actions Required

• Update the WPMobile.App plugin to a version newer than 11.71 if a patched version is available
• Review the Patchstack security advisory for vendor-specific remediation guidance
• Implement Content-Security-Policy headers to restrict script execution sources
• Consider temporarily disabling the WPMobile.App plugin until a patch is applied

Patch Information

Organizations should monitor the WPMobile.App plugin update channels and the Patchstack vulnerability database for official patch releases. Apply security updates promptly once available. Ensure that WordPress core and all other plugins are also kept up to date to maintain overall site security posture.

Workarounds

• Deploy a Web Application Firewall with XSS filtering rules to block malicious input patterns
• Implement strict Content-Security-Policy headers that restrict inline script execution and limit script sources
• Apply server-side input validation and output encoding at the application level where possible
• Restrict access to WordPress admin areas and limit user permissions to reduce attack surface

# Example: Add Content-Security-Policy header in Apache .htaccess
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline';"

# Example: Add Content-Security-Policy header in Nginx
add_header Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline';";
