CVE-2025-7651: Earnware Connect WordPress XSS Vulnerability

CVE-2025-7651 Overview

CVE-2025-7651 is a Stored Cross-Site Scripting (XSS) vulnerability in the Earnware Connect plugin for WordPress. The flaw resides in the plugin's ew_hasrole shortcode, which fails to properly sanitize user-supplied attributes before rendering them in page output. All versions up to and including 1.0.74 are affected. Authenticated attackers holding contributor-level access or above can inject arbitrary JavaScript into pages. The injected scripts execute in the browser context of any user who visits the affected page, enabling session theft, forced redirects, and administrative account takeover. The vulnerability is tracked under CWE-79.

Critical Impact
Authenticated contributors can persist malicious JavaScript that runs in the browser sessions of visitors and administrators, leading to potential site compromise.

Affected Products

Earnware Connect plugin for WordPress — all versions up to and including 1.0.74

Technical Details for CVE-2025-7651

Vulnerability Analysis

The Earnware Connect plugin exposes a shortcode named ew_hasrole intended to conditionally render content based on a visitor's role. The shortcode handler accepts attributes from post or page content and echoes those attributes back into the rendered HTML without adequate sanitization or output escaping. Because WordPress shortcodes execute at render time and their attributes are stored inside post content, malicious payloads persist in the database and re-execute on every page load.

Contributor-level users can create draft posts and embed the shortcode with attacker-controlled attributes. When an editor or administrator previews or publishes the content, the payload runs under their session, providing a path from a low-privilege account to full site takeover.

Root Cause

The root cause is missing input validation on shortcode attributes combined with the absence of output escaping functions such as esc_attr() or esc_html() when the plugin emits attribute values into HTML. This maps directly to CWE-79: Improper Neutralization of Input During Web Page Generation.

Attack Vector

The attack requires network access to the WordPress site and authenticated contributor privileges. An attacker submits a post containing the ew_hasrole shortcode with a crafted attribute value carrying JavaScript. Once the post is viewed by another user, the payload executes in that user's browser. The scope-changed impact reflects that code injected into the WordPress render pipeline crosses the boundary between the contributor's authored content and the trusted site chrome viewed by administrators.

No verified exploit code is public. See the Wordfence Vulnerability Report for additional analysis.

Detection Methods for CVE-2025-7651

Indicators of Compromise

Post or page content containing [ew_hasrole ...] shortcode invocations with attribute values that include <script>, javascript:, or HTML event handlers such as onerror= and onload=
Unexpected outbound requests from administrator browsers to attacker-controlled domains shortly after visiting plugin-rendered pages
New administrator accounts, modified user roles, or unexpected plugin installations following contributor account activity

Detection Strategies

Query the wp_posts table for shortcode occurrences: SELECT ID, post_author FROM wp_posts WHERE post_content LIKE '%[ew_hasrole%' and review each match for script content in attributes
Enable a Web Application Firewall (WAF) rule that inspects POST bodies to /wp-admin/post.php for shortcode attributes containing HTML tags or JavaScript URI schemes
Correlate contributor account activity with subsequent editor or administrator page views to identify potential exploitation chains

Monitoring Recommendations

Alert on new posts or edits authored by contributor-role accounts, particularly those referencing plugin shortcodes
Monitor browser telemetry from privileged users for anomalous script execution or Document Object Model (DOM) modifications on plugin-rendered pages
Review WordPress audit logs for role changes, plugin installations, or option modifications not attributable to legitimate administrative work

How to Mitigate CVE-2025-7651

Immediate Actions Required

Update the Earnware Connect plugin to a version newer than 1.0.74 as soon as the vendor publishes a fix, per the plugin page
Audit all existing posts and pages for the ew_hasrole shortcode and remove any attributes containing script content
Review contributor and author accounts, revoking access for unrecognized or dormant users

Patch Information

Refer to the WordPress plugin changeset for the vendor code change. The Wordfence Vulnerability Report tracks patched version details as they become available.

Workarounds

Deactivate the Earnware Connect plugin until a patched version is installed
Restrict contributor-level and higher accounts to trusted users only, and require multi-factor authentication for all editorial roles
Deploy a WordPress-aware WAF rule that blocks shortcode attributes containing <, >, or javascript: sequences

bash

# Temporarily deactivate the vulnerable plugin using WP-CLI
wp plugin deactivate earnware-connect

# Search post content for the vulnerable shortcode usage
wp db query "SELECT ID, post_title, post_author FROM wp_posts WHERE post_content LIKE '%[ew_hasrole%' AND post_status IN ('publish','draft','pending');"
