CVE-2026-6549: Logo Manager For Enamad WordPress XSS Flaw

CVE-2026-6549 Overview

CVE-2026-6549 is a Stored Cross-Site Scripting (XSS) vulnerability in the Logo Manager For Enamad plugin for WordPress. The flaw affects all versions up to and including 0.7.4. The vulnerability resides in the title attribute of the vc_enamad_namad, vc_enamad_shamed, and vc_enamad_custom shortcodes. The plugin fails to sanitize input and escape output on user-supplied attributes [CWE-79]. Authenticated attackers with contributor-level access or above can inject arbitrary web scripts that execute when any user views an affected page.

Critical Impact
Authenticated contributors can inject persistent JavaScript that runs in the browsers of site visitors and administrators, enabling session theft, redirection, and administrative account takeover.

Affected Products

Logo Manager For Enamad plugin for WordPress
All versions up to and including 0.7.4

Technical Details for CVE-2026-6549

Vulnerability Analysis

The Logo Manager For Enamad plugin registers three shortcodes used to render trust badges and custom logos: vc_enamad_namad, vc_enamad_shamed, and vc_enamad_custom. Each shortcode accepts a title attribute that is rendered into the page output. The plugin reflects the attribute value into HTML without applying WordPress sanitization functions such as esc_attr() or sanitize_text_field().

Because the payload is stored in post content, the script persists across page loads and fires for every visitor who accesses the affected page. Exploitation requires authentication at the contributor role or higher, which is a low barrier on multi-author WordPress installations. The vulnerability has a changed scope, allowing injected scripts to act in the context of any user who views the page, including administrators.

Root Cause

The root cause is insufficient input sanitization and missing output escaping on shortcode attributes within the plugin's widgets.php file. The title parameter is passed directly into rendered markup without encoding HTML metacharacters. Standard WordPress secure coding practice requires attribute values to be wrapped with esc_attr() and content destined for HTML bodies to be passed through wp_kses_post() or esc_html().

Attack Vector

An attacker with a contributor account creates or edits a post containing one of the vulnerable shortcodes. The attacker supplies a malicious title value such as a payload that closes the surrounding attribute and introduces an onerror, onload, or inline <script> element. When the post is previewed, published, or rendered to any visitor, the browser executes the injected script in the context of the WordPress origin. The attack vector is network-based and does not require user interaction beyond visiting the page.

// Example exploitation pattern (sanitized, conceptual)
// Attacker submits a shortcode with a crafted title attribute:
// [vc_enamad_namad title='"><script>/* attacker-controlled JS */</script>']
// The plugin renders the value into HTML without escaping, executing the script
// in every visitor's browser session.

Detection Methods for CVE-2026-6549

Indicators of Compromise

Post or page content containing vc_enamad_namad, vc_enamad_shamed, or vc_enamad_custom shortcodes with title values that include <, >, ", script, onerror, or onload tokens
Unexpected outbound requests from visitor browsers to attacker-controlled domains shortly after rendering pages that include these shortcodes
New or modified posts authored by contributor-level accounts that embed the affected shortcodes

Detection Strategies

Query the wp_posts table for post_content matching the three shortcode names and inspect title attribute values for HTML or JavaScript syntax
Review WordPress audit logs for contributor accounts creating or editing posts that include Enamad shortcodes
Scan rendered pages with a headless browser and a Content Security Policy (CSP) report endpoint to capture script execution violations

Monitoring Recommendations

Monitor the WordPress user_register and set_user_role events to track contributor and author role assignments
Alert on file modifications under wp-content/plugins/logo-manager-for-enamad/ and on outbound HTTP requests from page rendering processes
Enable WordPress debug logging and forward web server access logs to a centralized analytics platform for correlation with user activity

How to Mitigate CVE-2026-6549

Immediate Actions Required

Update the Logo Manager For Enamad plugin to a version newer than 0.7.4 once the vendor releases a patched release
If no patched version is available, deactivate and remove the plugin from all affected WordPress sites
Audit existing posts and pages for the three vulnerable shortcodes and remove or sanitize any suspicious title attribute values
Rotate session cookies and reset administrator passwords if injected scripts may have executed in privileged sessions

Patch Information

At the time of publication, no fixed version is identified in the NVD record. Refer to the Wordfence Vulnerability Report and the WordPress Plugin Page for the latest release information. The vulnerable code path is documented in the WordPress Plugin Source Code.

Workarounds

Restrict contributor and author role assignments to trusted users only, and review existing low-privilege accounts
Deploy a web application firewall (WAF) rule that blocks shortcode submissions containing HTML tags or JavaScript event handlers in the title parameter
Apply a strict Content Security Policy that disallows inline scripts on pages served by WordPress to reduce the impact of stored XSS payloads

bash

# Example: disable the plugin via WP-CLI until a patched release is available
wp plugin deactivate logo-manager-for-enamad
wp plugin delete logo-manager-for-enamad

# Audit existing posts for vulnerable shortcodes
wp db query "SELECT ID, post_title FROM wp_posts WHERE post_content REGEXP 'vc_enamad_(namad|shamed|custom)'"
