CVE-2025-30988: Elite Video Player Stored XSS Vulnerability

CVE-2025-30988 Overview

CVE-2025-30988 is a Stored Cross-Site Scripting (XSS) vulnerability affecting the Elite Video Player WordPress plugin developed by CreativeMedia. This vulnerability stems from improper neutralization of input during web page generation, classified under CWE-79. Attackers can inject malicious scripts that persist in the application and execute in the context of other users' browsers when they access the affected pages.

Critical Impact

Stored XSS vulnerabilities allow attackers to inject persistent malicious scripts that execute whenever users view the compromised content, potentially leading to session hijacking, credential theft, or malware distribution.

Affected Products

• Elite Video Player WordPress Plugin versions up to and including 10.0.5
• WordPress installations using the vulnerable elite-video-player plugin
• All websites running affected versions of Elite Video Player

Technical Details for CVE-2025-30988

Vulnerability Analysis

This Stored XSS vulnerability occurs due to insufficient input sanitization within the Elite Video Player plugin. When user-supplied data is incorporated into web pages without proper encoding or validation, attackers can inject JavaScript code that becomes permanently stored in the application's database. Unlike reflected XSS attacks that require victims to click malicious links, stored XSS payloads execute automatically whenever a user visits the affected page, significantly increasing the attack's reach and impact.

The vulnerability affects the plugin's handling of video player configuration or content fields, where malicious script tags or event handlers can be injected and subsequently rendered to all visitors viewing the compromised video content.

Root Cause

The root cause is improper neutralization of user-controlled input before it is included in dynamically generated web pages. The Elite Video Player plugin fails to properly sanitize, validate, or encode user input before storing it in the database and subsequently rendering it in HTML output. This allows attackers to inject arbitrary HTML and JavaScript code that persists across page loads.

Attack Vector

An authenticated attacker with sufficient privileges to create or modify video player content can inject malicious JavaScript payloads into vulnerable input fields. Once stored, these payloads execute in the browsers of all users who view the affected content. The attack can be leveraged to:

• Steal session cookies and authentication tokens
• Perform actions on behalf of authenticated users
• Redirect users to malicious websites
• Deface website content
• Distribute malware through drive-by downloads

The vulnerability is exploited by inserting script tags or JavaScript event handlers (such as onload, onerror, or onclick) into input fields that are not properly sanitized before being rendered in the page output. For detailed technical information, see the Patchstack Vulnerability Report.

Detection Methods for CVE-2025-30988

Indicators of Compromise

• Unexpected JavaScript code or <script> tags appearing in video player content fields or database entries
• User reports of browser redirects or unexpected pop-ups when viewing video content
• Anomalous outbound connections to unknown domains originating from client browsers
• Suspicious entries in web server logs showing encoded or obfuscated script payloads in POST requests

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common XSS payload patterns in HTTP requests
• Implement Content Security Policy (CSP) headers to prevent execution of inline scripts and restrict script sources
• Conduct regular security scans of the WordPress database for stored XSS payloads in plugin-related tables
• Monitor for unusual user behavior patterns that may indicate session hijacking via XSS

Monitoring Recommendations

• Enable detailed logging for all POST requests to WordPress admin pages, particularly those related to the Elite Video Player plugin
• Configure browser-based monitoring to detect and report CSP violations
• Implement real-time alerting for database modifications to video player content tables
• Review access logs for patterns indicating reconnaissance or exploitation attempts

How to Mitigate CVE-2025-30988

Immediate Actions Required

• Update the Elite Video Player plugin to a patched version as soon as one becomes available from the vendor
• Audit existing video player content for signs of injected malicious scripts and sanitize any compromised entries
• Implement strict Content Security Policy headers to mitigate the impact of potential XSS exploitation
• Consider temporarily disabling the plugin if a patch is not available and the risk is deemed unacceptable

Patch Information

Users should monitor the WordPress plugin repository and the vendor's official channels for security updates addressing this vulnerability. The Patchstack Vulnerability Report provides additional details and may be updated when a fix becomes available.

Workarounds

• Implement server-side input validation and output encoding for all user-controlled content rendered by the plugin
• Deploy a Web Application Firewall with XSS-specific rule sets to filter malicious payloads
• Restrict plugin access to only trusted administrators who require video player functionality
• Apply the principle of least privilege by limiting which user roles can create or edit video player content

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

# Or in nginx configuration
add_header Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none';";
