CVE-2025-47662 Overview
CVE-2025-47662 is a stored cross-site scripting (XSS) vulnerability [CWE-79] in the Woobox WordPress plugin. The flaw stems from improper neutralization of user input during web page generation. Attackers with low-privileged authenticated access can inject persistent JavaScript payloads that execute in the browsers of visitors and administrators. The vulnerability affects all Woobox plugin versions up to and including 1.6. Successful exploitation requires user interaction and crosses a security scope boundary, enabling session theft, credential harvesting, and administrative takeover through the compromised plugin context.
Critical Impact
Authenticated attackers can store malicious scripts that execute against any user rendering the affected plugin output, including WordPress administrators.
Affected Products
- Woobox WordPress plugin versions through 1.6
- WordPress sites with the Woobox plugin installed and activated
- Any end-user browser rendering compromised plugin output

Technical Details for CVE-2025-47662
Vulnerability Analysis
The Woobox plugin fails to sanitize or encode user-supplied input before writing it into HTML output. An authenticated user with contributor-level or higher access can submit crafted input containing HTML or JavaScript. The plugin stores the payload and later renders it without context-aware escaping. When another user loads the affected page, the browser parses and executes the injected script within the site's origin.
Because the scope metric is Changed, the executed script escapes the plugin's security context and operates against the broader WordPress session. This enables attackers to perform actions on behalf of victims, including administrators, if they are tricked into visiting the compromised page.
Root Cause
The root cause is missing output encoding on user-controlled data paths. WordPress provides escaping helpers such as esc_html(), esc_attr(), and wp_kses(), but the vulnerable code paths in Woobox 1.6 and earlier emit stored input directly into the DOM. The absence of input validation combined with unsafe output rendering produces the stored XSS condition classified under [CWE-79].
Attack Vector
Exploitation requires network access, low privileges, and user interaction. An attacker authenticates to WordPress, navigates to a Woobox-controlled input field, and submits a payload such as an <script> tag or event-handler attribute. The payload persists in the database. When a victim loads the page containing the stored content, their browser executes the attacker's JavaScript under the site's origin, enabling cookie theft, forced actions, or redirection to attacker-controlled infrastructure.
No verified exploit code is publicly available. See the Patchstack Vulnerability Report for additional technical context.
Detection Methods for CVE-2025-47662
Indicators of Compromise
- WordPress database entries containing <script> tags, javascript: URIs, or event handlers such as onerror= and onload= within Woobox-managed fields
- Unexpected outbound requests from administrator browsers to unknown domains after visiting plugin pages
- New or modified WordPress administrator accounts created without authorized change records
Detection Strategies
- Audit the wp_posts, wp_postmeta, and wp_options tables for stored HTML or script content in rows associated with the Woobox plugin
- Deploy a web application firewall rule to flag HTTP POST requests to Woobox endpoints containing script tags or JavaScript event handlers
- Review web server access logs for suspicious parameter values submitted by contributor or editor accounts
Monitoring Recommendations
- Monitor WordPress administrator sessions for anomalous API calls originating from browser contexts
- Alert on changes to the plugin directory and on new administrator role assignments
- Enable Content Security Policy (CSP) reporting to capture blocked inline script execution attempts
How to Mitigate CVE-2025-47662
Immediate Actions Required
- Deactivate the Woobox plugin on all WordPress installations running version 1.6 or earlier until a patched release is confirmed
- Review all content and configuration fields managed by Woobox for stored script payloads and remove any suspicious entries
- Rotate WordPress administrator credentials and invalidate active sessions if exploitation is suspected
Patch Information
At the time of publication, the advisory lists the vulnerable range as versions up to and including 1.6. Monitor the vendor's channel and the Patchstack Vulnerability Report for a fixed release and upgrade immediately once available.
Workarounds
- Restrict contributor, author, and editor roles to trusted users only, since exploitation requires an authenticated account
- Deploy a Content Security Policy that blocks inline scripts and restricts script sources to approved origins
- Place a web application firewall in front of WordPress with rules that strip or block HTML tags in Woobox request parameters
# Example WordPress CLI command to deactivate the plugin pending a patch
wp plugin deactivate woobox --all
