CVE-2025-22747 Overview
CVE-2025-22747 is a stored Cross-Site Scripting (XSS) vulnerability affecting the tormorten Foundation Columns WordPress plugin. The flaw stems from improper neutralization of user-supplied input during web page generation, classified under [CWE-79]. Attackers with low-privilege authenticated access can inject persistent JavaScript payloads that execute in the browsers of site visitors and administrators. The vulnerability affects all versions of Foundation Columns up to and including 0.8. Successful exploitation can lead to session hijacking, credential theft, or unauthorized administrative actions within the WordPress environment.
Critical Impact
Authenticated attackers can store malicious scripts that execute in victim browsers, enabling account takeover, content manipulation, and lateral movement within WordPress sites.
Affected Products
- tormorten Foundation Columns plugin for WordPress
- All versions from initial release through 0.8
- WordPress sites with the plugin installed and activated

Technical Details for CVE-2025-22747
Vulnerability Analysis
The vulnerability resides in the Foundation Columns plugin's handling of user-supplied input passed to page rendering routines. The plugin fails to sanitize or encode input before storing it and subsequently rendering it in HTML output. This allows an attacker to persist arbitrary JavaScript in the database. When another user loads the affected page, the browser executes the injected script in the site's origin context.
Stored XSS carries a higher impact than reflected variants because payloads execute for every visitor to the compromised page. Attackers can weaponize the flaw to steal authentication cookies, perform CSRF-style actions against administrators, or pivot to plugin-based privilege escalation.
Root Cause
The root cause is missing output encoding and inadequate input validation in the plugin's column configuration handlers. The plugin trusts input submitted by authenticated contributors and stores it without applying WordPress sanitization functions such as wp_kses_post(), esc_html(), or esc_attr() at render time.
Attack Vector
Exploitation requires an authenticated user account with at least contributor-level privileges and user interaction from a victim who views the affected page. The scope changes because injected script executes in the WordPress admin context when administrators view the poisoned content. Refer to the Patchstack XSS Vulnerability Advisory for additional technical context.
Detection Methods for CVE-2025-22747
Indicators of Compromise
- Unexpected <script> tags, on* event handlers, or javascript: URIs stored in WordPress wp_posts or wp_postmeta tables containing Foundation Columns shortcode data
- Outbound HTTP requests from administrator browsers to unfamiliar domains shortly after loading pages that use Foundation Columns shortcodes
- New administrator accounts, unexpected plugin installations, or modified user roles following visits to affected pages
Detection Strategies
- Audit database content for HTML or JavaScript payloads embedded within Foundation Columns shortcode attributes and stored post content
- Deploy a Web Application Firewall (WAF) rule set that flags XSS patterns in POST requests targeting /wp-admin/post.php and /wp-admin/admin-ajax.php
- Monitor WordPress activity logs for content edits by contributor or author accounts that include HTML markup in Foundation Columns fields
Monitoring Recommendations
- Enable Content Security Policy (CSP) headers with strict script-src directives and log CSP violation reports
- Track authentication events for administrative accounts, focusing on session token reuse from unusual IP addresses
- Alert on plugin file modifications and unexpected changes to WordPress core configuration files
How to Mitigate CVE-2025-22747
Immediate Actions Required
- Deactivate and remove the Foundation Columns plugin until a patched release is confirmed available
- Audit all contributor, author, and editor accounts and revoke access for untrusted users
- Scan existing posts and pages for stored XSS payloads and remove any injected script content
- Rotate WordPress administrator passwords and invalidate active sessions across the site
Patch Information
As of the last NVD update on 2026-06-17, no fixed version has been identified beyond 0.8. Site administrators should monitor the Patchstack XSS Vulnerability Advisory for patch availability and remove the plugin in the interim.
Workarounds
- Restrict content editing permissions to trusted administrator accounts only
- Deploy a WAF with signatures that block XSS injection patterns in WordPress POST parameters
- Implement a strict Content Security Policy that disallows inline scripts and unauthorized script sources
- Replace Foundation Columns with an actively maintained alternative that provides equivalent column layout functionality
# Example CSP header configuration for Apache to mitigate stored XSS
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; base-uri 'self'; report-uri /csp-report"
# Disable the vulnerable plugin via WP-CLI
wp plugin deactivate foundation-columns
wp plugin delete foundation-columns
