CVE-2025-24706 Overview
CVE-2025-24706 is a stored cross-site scripting (XSS) vulnerability in the MultiVendorX plugin for WordPress, also known as dc-woocommerce-multi-vendor. The flaw affects all versions up to and including 4.2.13. It stems from improper neutralization of user-supplied input during web page generation, classified under [CWE-79]. An authenticated attacker with low privileges can inject malicious scripts that persist in the application and execute in the browsers of other users, including administrators.
Critical Impact
Attackers with low-privilege access can store malicious JavaScript that executes in victim browsers, enabling session theft, account takeover, and administrative action hijacking within WooCommerce multi-vendor marketplaces.
Affected Products
- MultiVendorX plugin for WordPress (dc-woocommerce-multi-vendor)
- All versions from unspecified initial release through 4.2.13
- WordPress sites running WooCommerce with the MultiVendorX extension enabled

Technical Details for CVE-2025-24706
Vulnerability Analysis
The MultiVendorX plugin extends WooCommerce to support multi-vendor marketplaces. The vulnerability resides in input handling paths that accept vendor-controlled data and render it back into pages without proper output encoding or sanitization. Because the payload is stored server-side, it executes each time a victim loads an affected page.
Successful exploitation requires an attacker to authenticate with low privileges, such as a registered vendor account. User interaction is also required for the payload to trigger. The scope is changed, meaning the injected script executes in a security context different from the vulnerable component, which amplifies the reach into administrative sessions.
Root Cause
The plugin fails to apply sufficient sanitization or context-aware output encoding to one or more input fields exposed to vendor-level users. Data persists in the WordPress database and is later echoed into HTML responses, allowing arbitrary JavaScript to execute in the victim's browser session.
Attack Vector
An authenticated vendor submits crafted input containing JavaScript payloads through a vulnerable plugin interface. The payload is stored and later rendered to marketplace administrators or shoppers viewing related pages. When the victim loads the affected view, the script executes under the site's origin and can read cookies, perform actions on behalf of the user, or pivot to further site compromise. Refer to the Patchstack Security Vulnerability Report for technical details.
Detection Methods for CVE-2025-24706
Indicators of Compromise
- Unexpected <script>, javascript:, or event-handler attributes (such as onerror, onload) stored in WordPress wp_posts, wp_postmeta, or MultiVendorX vendor profile tables.
- Outbound requests from administrator browser sessions to unfamiliar domains shortly after visiting vendor pages.
- Unexplained administrator account activity, including plugin installation, user creation, or option changes originating from browser sessions.
Detection Strategies
- Audit vendor-submitted content and profile fields for HTML tags and encoded JavaScript payloads.
- Review web server access logs for POST requests from vendor accounts containing payload fragments such as %3Cscript or onerror=.
- Deploy a Web Application Firewall (WAF) rule set to flag reflected and stored XSS payload patterns targeting WooCommerce endpoints.
Monitoring Recommendations
- Monitor authenticated vendor sessions for abnormal input submissions and content modifications.
- Alert on Content Security Policy (CSP) violation reports originating from marketplace pages.
- Track administrator session activity for anomalous API calls or privilege changes following vendor page visits.
How to Mitigate CVE-2025-24706
Immediate Actions Required
- Update the MultiVendorX plugin to a version later than 4.2.13 as soon as the vendor publishes a patched release.
- Audit existing vendor accounts and stored vendor content for malicious payloads and remove them.
- Rotate administrator credentials and invalidate active sessions if exploitation is suspected.
Patch Information
At the time of publication, the vulnerability affects MultiVendorX through 4.2.13. Review the Patchstack Security Vulnerability Report for the latest fixed version and patch guidance from MultiVendorX.
Workarounds
- Restrict vendor registration and require manual approval of new vendor accounts until patched.
- Deploy a strict Content Security Policy (CSP) that disallows inline scripts and limits script sources to trusted origins.
- Enable a WAF with managed rules for stored XSS targeting WordPress and WooCommerce plugins.
- Temporarily disable the MultiVendorX plugin on production sites if no fixed version is available and the risk is unacceptable.
# Example WordPress CLI steps to disable the plugin and audit vendor content
wp plugin deactivate dc-woocommerce-multi-vendor
wp db query "SELECT ID, post_title FROM wp_posts WHERE post_content LIKE '%<script%' OR post_content LIKE '%onerror=%';"
