CVE-2025-28971 Overview
CVE-2025-28971 is a stored cross-site scripting (XSS) vulnerability in the CWD Web Designer Easy Elements Hider plugin for WordPress. The flaw affects all versions of the easy-elements-hider plugin up to and including 2.0. The vulnerability results from improper neutralization of user-supplied input during web page generation, classified as [CWE-79]. Authenticated attackers with high privileges can inject persistent JavaScript payloads that execute in the browsers of other users viewing affected pages.
Critical Impact
Attackers can inject persistent JavaScript that executes in victim browsers, enabling session theft, administrative action hijacking, and downstream compromise of WordPress site visitors.
Affected Products
- CWD Web Designer Easy Elements Hider plugin for WordPress
- All versions from initial release through 2.0
- WordPress installations with the vulnerable plugin activated

Technical Details for CVE-2025-28971
Vulnerability Analysis
The Easy Elements Hider plugin allows administrators to hide elements on WordPress pages using CSS selectors and configuration inputs. The plugin fails to properly sanitize or encode input supplied through its configuration interface before storing it and later rendering it into generated web pages. This omission allows an attacker with elevated privileges to persist script payloads within plugin-managed content.
When a victim loads a page that includes the stored payload, the browser executes the attacker-controlled JavaScript in the context of the WordPress site's origin. Exploitation requires user interaction, and the vulnerability crosses a security scope boundary, since payloads injected via administrator configuration can execute in the sessions of other authenticated users or site visitors.
Root Cause
The root cause is missing output encoding and input sanitization on plugin fields that accept user-supplied values. The plugin stores raw input in the WordPress database and echoes it into HTML output without applying WordPress escaping functions such as esc_html(), esc_attr(), or wp_kses(). As a result, HTML and JavaScript characters pass through unaltered to the rendered document.
Attack Vector
The attack is network-based and requires an authenticated account with high privileges on the target WordPress site. An attacker submits a crafted payload through the plugin's configuration interface. The payload persists in the database and executes each time a user renders a page containing the injected element. Detailed reproduction steps are documented in the Patchstack XSS Vulnerability Report.
Detection Methods for CVE-2025-28971
Indicators of Compromise
- Unexpected <script> tags, event handlers, or javascript: URIs stored within Easy Elements Hider plugin options in the wp_options table
- Outbound HTTP requests from visitor browsers to unknown domains originating from pages managed by the plugin
- WordPress administrator accounts creating or modifying Easy Elements Hider configuration entries containing HTML markup
Detection Strategies
- Inspect stored plugin configuration values for HTML, script tags, or encoded payloads that deviate from CSS-selector-only content
- Review WordPress audit logs for suspicious edits to plugin settings by administrator accounts, especially outside expected change windows
- Deploy Content Security Policy (CSP) reporting to surface inline script execution from pages using the plugin
Monitoring Recommendations
- Alert on modifications to wp_options rows tied to the easy-elements-hider plugin
- Monitor administrator session activity for anomalous logins, geolocations, or user-agent strings preceding plugin configuration changes
- Track browser-side JavaScript errors and CSP violation reports for pages served by the affected plugin
How to Mitigate CVE-2025-28971
Immediate Actions Required
- Deactivate the Easy Elements Hider plugin on all WordPress sites until a fixed version is confirmed available from the vendor
- Audit existing plugin configuration entries and remove any values containing HTML tags, event handlers, or script content
- Rotate credentials for administrator accounts that could have introduced malicious payloads and enforce multi-factor authentication
Patch Information
No patched version is identified in the enriched CVE data. The vulnerability affects Easy Elements Hider through version 2.0. Administrators should consult the Patchstack advisory and the WordPress plugin repository for updates before reactivating the plugin.
Workarounds
- Remove the plugin entirely and implement element-hiding logic through a maintained theme or trusted alternative plugin
- Restrict administrator privileges to a minimal set of trusted accounts to reduce the attack surface for privileged XSS injection
- Deploy a web application firewall (WAF) rule set that blocks XSS payload patterns submitted to WordPress admin endpoints
# Configuration example: disable the plugin via WP-CLI
wp plugin deactivate easy-elements-hider
wp plugin delete easy-elements-hider
