CVE-2025-49045: Super Interactive Maps XSS Vulnerability

CVE-2025-49045 Overview

CVE-2025-49045 is a Reflected Cross-Site Scripting (XSS) vulnerability affecting the Super Interactive Maps WordPress plugin developed by highwarden. The vulnerability stems from improper neutralization of user-supplied input during web page generation, allowing attackers to inject malicious scripts that execute in the context of a victim's browser session.

Critical Impact

This reflected XSS vulnerability enables attackers to execute arbitrary JavaScript code in the browsers of authenticated WordPress users, potentially leading to session hijacking, credential theft, or administrative account compromise.

Affected Products

• Super Interactive Maps WordPress Plugin versions up to and including 2.3
• WordPress sites utilizing the super-interactive-maps plugin

Technical Details for CVE-2025-49045

Vulnerability Analysis

This vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation), commonly known as Cross-Site Scripting. The Super Interactive Maps plugin fails to properly sanitize and escape user-controlled input before reflecting it back in the HTML response. When a victim clicks a malicious link crafted by an attacker, the injected script executes within the victim's browser session with full access to the page's DOM and any associated cookies or session tokens.

Reflected XSS attacks require user interaction—typically clicking a malicious link—but can be highly effective when combined with social engineering techniques. In the context of WordPress, successful exploitation could allow an attacker to perform actions as an authenticated administrator, modify site content, install malicious plugins, or exfiltrate sensitive data.

Root Cause

The root cause of this vulnerability lies in insufficient input validation and output encoding within the Super Interactive Maps plugin. User-supplied data is included in the HTML response without proper sanitization, allowing specially crafted payloads containing JavaScript code to be executed by the browser. The plugin likely fails to implement WordPress security best practices such as using esc_html(), esc_attr(), or wp_kses() functions for output escaping.

Attack Vector

The attack vector for this reflected XSS vulnerability involves crafting a malicious URL containing JavaScript payload in a vulnerable parameter. When a victim visits the crafted URL, the malicious script is reflected from the server and executed in the victim's browser. The attacker typically distributes the malicious link through phishing emails, social media, or by embedding it on compromised websites.

The vulnerability affects the plugin's input handling mechanism where user-supplied data is directly echoed back to the page without proper encoding. An attacker can leverage this to steal session cookies, redirect users to phishing pages, or perform actions on behalf of authenticated users.

Detection Methods for CVE-2025-49045

Indicators of Compromise

• Unusual URL parameters containing encoded JavaScript payloads in requests to WordPress pages utilizing Super Interactive Maps
• Web server logs showing requests with suspicious script tags or JavaScript event handlers in query strings
• Browser-based security alerts or Content Security Policy violations related to inline script execution

Detection Strategies

• Review web application firewall (WAF) logs for requests containing XSS payloads targeting the Super Interactive Maps plugin
• Monitor for anomalous admin activity following user clicks on external links, which may indicate successful XSS exploitation
• Implement Content Security Policy (CSP) headers to detect and block inline script execution attempts

Monitoring Recommendations

• Enable detailed logging for WordPress plugin activity and user authentication events
• Configure WAF rules to detect common XSS patterns in URL parameters and POST data
• Monitor for changes to WordPress user roles, plugin installations, or site settings that could indicate post-exploitation activity

How to Mitigate CVE-2025-49045

Immediate Actions Required

• Update the Super Interactive Maps plugin to a patched version when available from the vendor
• Consider temporarily disabling the Super Interactive Maps plugin if it is not critical to site functionality
• Implement a Web Application Firewall (WAF) with XSS protection rules to filter malicious requests
• Review WordPress user accounts for unauthorized changes or newly created administrator accounts

Patch Information

No official patch information is available at this time. Organizations should monitor the Patchstack XSS Vulnerability Report for updates regarding remediation guidance and vendor patches. Consider reaching out to the plugin developer (highwarden) directly for patch availability information.

Workarounds

• Implement Content Security Policy (CSP) headers with strict script-src directives to mitigate the impact of XSS attacks
• Use a WordPress security plugin that provides virtual patching capabilities for known vulnerabilities
• Restrict access to WordPress admin pages to trusted IP addresses where feasible
• Educate users about the risks of clicking untrusted links, particularly those containing unusual URL parameters

# Example: Add Content Security Policy headers in .htaccess
# Place in WordPress root directory
<IfModule mod_headers.c>
    Header set Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline';"
    Header set X-Content-Type-Options "nosniff"
    Header set X-XSS-Protection "1; mode=block"
</IfModule>
