CVE-2025-47675: Woobox Plugin DOM-Based XSS Vulnerability

CVE-2025-47675 is a DOM-based cross-site scripting vulnerability in the Woobox WordPress plugin affecting versions up to 1.6. Attackers can inject malicious scripts through improper input neutralization. This article covers technical details, impact assessment, affected versions, and mitigation strategies.

CVE-2025-47675 Overview

CVE-2025-47675 is a DOM-based Cross-Site Scripting (XSS) vulnerability in the Woobox WordPress plugin. The flaw stems from improper neutralization of input during web page generation, classified under [CWE-79]. Attackers can inject malicious scripts that execute in the browser context of authenticated users who interact with crafted content. The vulnerability affects Woobox versions up to and including 1.6.

Critical Impact
Successful exploitation enables script execution in a victim's browser session, allowing session data theft, unauthorized actions, and potential site defacement within the WordPress environment.

Affected Products

Woobox WordPress plugin versions up to and including 1.6
WordPress installations with the Woobox plugin enabled
Sites permitting low-privilege authenticated users to interact with vulnerable plugin components

Technical Details for CVE-2025-47675

Vulnerability Analysis

The Woobox plugin fails to properly sanitize user-controlled input before it is written to the Document Object Model (DOM). Client-side JavaScript in the plugin processes attacker-influenced values and reflects them into the page without adequate encoding. This creates a DOM-based XSS sink reachable through crafted URLs or parameters.

Exploitation requires an authenticated user with low privileges and user interaction, such as clicking a crafted link. Because the payload executes in the victim's browser under the WordPress site origin, it can access cookies, tokens, and DOM content available to that session. The scope-changed impact indicates the vulnerability can affect resources beyond the immediately vulnerable component.

Root Cause

The root cause is missing or insufficient output encoding when reflecting URL fragments, query parameters, or other client-side inputs into the DOM. The plugin's JavaScript passes untrusted values to sinks such as innerHTML, document.write, or jQuery HTML manipulation methods without escaping HTML control characters. This aligns with CWE-79, improper neutralization of input during web page generation.

Attack Vector

An attacker crafts a URL containing a JavaScript payload targeting the vulnerable DOM sink in the Woobox plugin. The attacker delivers the URL to an authenticated WordPress user via phishing, chat, or a compromised page. When the victim loads the URL, the plugin's client-side code writes the payload into the page and the browser executes it. Refer to the Patchstack Woobox XSS Vulnerability advisory for additional technical context.

Detection Methods for CVE-2025-47675

Indicators of Compromise

Web server access logs containing URL parameters with <script>, javascript:, onerror=, or encoded equivalents targeting Woobox plugin endpoints
Unexpected outbound requests from user browsers to attacker-controlled domains after visiting WordPress pages hosting the plugin
WordPress audit log entries showing unauthorized administrative actions performed by authenticated users

Detection Strategies

Inventory WordPress sites and identify installations running Woobox 1.6 or earlier
Deploy a Web Application Firewall (WAF) rule set that inspects request parameters for XSS payload patterns targeting plugin routes
Review browser Content Security Policy (CSP) violation reports for inline script execution attempts on pages rendered by the Woobox plugin

Monitoring Recommendations

Enable verbose access logging on WordPress front-end and admin endpoints and forward logs to a centralized analytics platform
Alert on requests with URL fragments or query strings containing HTML tag characters against Woobox plugin URIs
Monitor authenticated session activity for anomalous privilege use following user clicks on external referrers

How to Mitigate CVE-2025-47675

Immediate Actions Required

Identify all WordPress instances using the Woobox plugin at version 1.6 or earlier
Disable or remove the Woobox plugin on affected sites until a patched release is verified and installed
Rotate authentication cookies and session tokens for administrator accounts that may have interacted with crafted URLs

Patch Information

At the time of publication, the vendor advisory tracked on Patchstack indicates the vulnerability affects Woobox through version 1.6. Administrators should consult the WordPress plugin repository for the latest Woobox release and apply any available update that addresses CVE-2025-47675.

Workarounds

Restrict access to the Woobox plugin functionality to trusted authenticated users through role-based access controls
Deploy a WAF rule to block requests containing script tags or JavaScript URI schemes in parameters processed by the plugin
Enforce a strict Content Security Policy that disallows inline scripts and untrusted script sources on pages rendering plugin content

bash

# Example WAF rule concept (ModSecurity syntax) to block XSS payloads on plugin URIs
SecRule REQUEST_URI "@contains /wp-content/plugins/woobox/" \
    "phase:2,deny,status:403,id:1004775,\
    chain,msg:'Potential XSS targeting Woobox plugin (CVE-2025-47675)'"
    SecRule ARGS|REQUEST_URI "@rx (?i)(<script|javascript:|onerror=|onload=)" "t:none,t:urlDecodeUni"
