CVE-2025-58992 Overview
CVE-2025-58992 is a stored cross-site scripting (XSS) vulnerability in the impleCode Product Catalog Simple plugin for WordPress. The flaw exists in the post-type-x component and affects all plugin versions up to and including 1.8.2. Authenticated attackers with low privileges can inject malicious scripts that persist in the database and execute in the browsers of users who view affected pages. The vulnerability is tracked under CWE-79 and requires user interaction to trigger the payload.
Critical Impact
Successful exploitation allows attackers to execute arbitrary JavaScript in the context of victim sessions, potentially leading to session hijacking, credential theft, and unauthorized administrative actions across the WordPress site.
Affected Products
- impleCode Product Catalog Simple plugin for WordPress
- All versions from initial release through 1.8.2
- WordPress sites using the post-type-x component

Technical Details for CVE-2025-58992
Vulnerability Analysis
The vulnerability stems from improper neutralization of user-supplied input during web page generation. The Product Catalog Simple plugin fails to sanitize and encode input passed through the post-type-x functionality before storing it and rendering it back to browsers. Attackers with contributor or author-level access can inject JavaScript payloads that persist across sessions. When administrators or other users view catalog entries containing injected content, the browser executes the attacker-controlled script within the site's origin. The scope change indicated by the CVSS vector confirms that impact extends beyond the vulnerable component to other browser contexts.
Root Cause
The root cause is missing output encoding and insufficient input sanitization in the plugin's product catalog rendering logic. The plugin accepts input from authenticated users and writes it into HTML output without applying WordPress escaping functions such as esc_html(), esc_attr(), or wp_kses(). This allows raw HTML and JavaScript to be persisted in the database and reflected in generated pages.
Attack Vector
Exploitation requires an authenticated user with low privileges to submit crafted input through plugin fields exposed by the post-type-x component. The payload is stored server-side and executed when a victim, typically an administrator, loads a page that renders the malicious content. Because the scope changes, the injected script runs in a browsing context that can affect other cookies and resources beyond the vulnerable component. See the Patchstack XSS Vulnerability Advisory for further technical details.
Detection Methods for CVE-2025-58992
Indicators of Compromise
- Unexpected <script> tags, on* event handlers, or javascript: URIs stored within product catalog post metadata or content fields
- WordPress audit log entries showing contributor or author accounts creating or editing product catalog entries containing HTML markup
- Outbound requests from administrator browser sessions to unfamiliar domains shortly after viewing catalog pages
Detection Strategies
- Scan the WordPress database wp_posts and wp_postmeta tables for HTML tags and JavaScript patterns in Product Catalog Simple entries
- Review web server access logs for POST requests to plugin endpoints from low-privileged accounts followed by administrator page views
- Deploy a web application firewall rule set that inspects requests to WordPress admin endpoints for XSS payload signatures
Monitoring Recommendations
- Monitor creation and modification events for the Product Catalog Simple custom post type and flag entries containing script markup
- Alert on new or unusual administrator sessions initiating actions immediately after viewing catalog content
- Track plugin version inventory across WordPress deployments to identify hosts still running versions at or below 1.8.2
How to Mitigate CVE-2025-58992
Immediate Actions Required
- Identify all WordPress installations running Product Catalog Simple version 1.8.2 or earlier
- Restrict contributor and author account provisioning until the plugin is updated
- Audit existing product catalog entries for injected HTML or JavaScript and remove malicious content
- Rotate administrator credentials and invalidate active sessions if suspicious catalog entries are found
Patch Information
At the time of publication, the vendor advisory referenced through Patchstack lists all versions through 1.8.2 as affected. Administrators should upgrade to a version later than 1.8.2 once released by the vendor and verify the fix through the plugin changelog.
Workarounds
- Temporarily deactivate the Product Catalog Simple plugin until a patched version is available
- Restrict access to the plugin's custom post type using capability management plugins to limit editing to trusted administrators
- Deploy a WordPress-aware web application firewall with rules that block stored XSS payloads targeting plugin endpoints
- Enforce a strict Content Security Policy that disallows inline script execution on WordPress admin and catalog pages
# Configuration example: disable the plugin via WP-CLI pending an upstream fix
wp plugin deactivate post-type-x
wp plugin status post-type-x
