CVE-2025-25073: Easy WP Tiles Stored XSS Vulnerability

CVE-2025-25073 Overview

CVE-2025-25073 is a stored Cross-Site Scripting (XSS) vulnerability in the Easy WP Tiles WordPress plugin developed by Vasilis Triantafyllou. The flaw stems from improper neutralization of input during web page generation [CWE-79]. All plugin versions up to and including 1 are affected. An authenticated attacker with high privileges can inject persistent JavaScript payloads that execute in the browser of any user who views the affected page. Because the injected script executes in a scope change (S:C), it can affect resources beyond the vulnerable component.

Critical Impact
Authenticated attackers can store malicious JavaScript that executes in visitor and administrator browsers, enabling session theft, forced actions, and content manipulation across the WordPress site.

Affected Products

Easy WP Tiles WordPress plugin (easy-wp-tiles)
All versions from n/a through version 1
WordPress sites running the vulnerable plugin

Technical Details for CVE-2025-25073

Vulnerability Analysis

The vulnerability is a stored XSS flaw in the Easy WP Tiles plugin for WordPress. Stored XSS occurs when user-supplied input is saved to persistent storage and later rendered in HTML without proper encoding or sanitization. Any user viewing the affected page executes the attacker-controlled script in their browser session.

Exploitation requires an authenticated user with high privileges to submit the malicious payload, and it requires a victim to view the affected content. The scope change indicates the injected script can influence resources outside the plugin's own security context, such as the WordPress admin interface or other site components.

Because the payload persists in the database, a single successful injection can compromise repeated visits by administrators, editors, and site visitors until the malicious content is removed.

Root Cause

The plugin fails to apply appropriate sanitization on input and appropriate output encoding when rendering that input in HTML. WordPress provides helpers such as sanitize_text_field(), wp_kses_post(), and esc_html() that were not correctly applied to the tile fields exposed by the plugin.

Attack Vector

The attack is delivered over the network through the plugin's authenticated administrative interface. An attacker with elevated plugin permissions submits a crafted payload containing JavaScript into a tile configuration field. The payload is stored in the WordPress database and rendered on subsequent page views, executing in the victim's browser context.

No verified proof-of-concept code is publicly available. See the Patchstack Vulnerability Advisory for advisory details.

Detection Methods for CVE-2025-25073

Indicators of Compromise

Unexpected <script> tags, inline event handlers (onerror, onload, onclick), or javascript: URIs stored in wp_postmeta or plugin option rows related to easy-wp-tiles.
Outbound requests from administrator browsers to attacker-controlled domains shortly after visiting pages containing plugin tiles.
New or modified WordPress administrator accounts, plugin installations, or option changes following an admin session that viewed tile content.

Detection Strategies

Audit database entries associated with the plugin for HTML entities or script fragments that should not appear in configuration fields.
Review web server access logs for administrator sessions accessing tile-related admin URLs followed by anomalous POST requests to WordPress AJAX or REST endpoints.
Deploy a Content Security Policy (CSP) with reporting enabled to surface unexpected inline script execution on pages rendering the plugin.

Monitoring Recommendations

Enable WordPress security logging plugins to capture changes to plugin options and post metadata performed by high-privilege accounts.
Monitor for anomalous authentication activity from privileged WordPress accounts, particularly session token reuse from unexpected IP addresses.
Alert on plugin file, user role, or option changes that occur immediately after an administrator loads a page containing an Easy WP Tiles tile.

How to Mitigate CVE-2025-25073

Immediate Actions Required

Deactivate and remove the Easy WP Tiles plugin from any WordPress site where it is installed until a patched release is confirmed.
Rotate credentials and invalidate active sessions for all administrator and editor accounts that could have viewed compromised tile content.
Audit the WordPress database, user roles, and installed plugins for signs of unauthorized modification.

Patch Information

No fixed version is listed in the advisory data. The vulnerability affects Easy WP Tiles from n/a through version 1. Review the Patchstack Vulnerability Advisory for the latest remediation status and monitor the plugin's WordPress.org listing for updates.

Workarounds

Restrict high-privilege WordPress roles to a minimum set of trusted users and enforce multi-factor authentication on those accounts.
Deploy a web application firewall (WAF) with rules that block common XSS payload patterns submitted to WordPress admin endpoints.
Implement a strict Content Security Policy (CSP) that disallows inline scripts and restricts script sources to trusted origins.

bash

# Configuration example: disable and remove the vulnerable plugin via WP-CLI
wp plugin deactivate easy-wp-tiles
wp plugin uninstall easy-wp-tiles
