CVE-2025-23594: Google Map With Fancybox XSS Vulnerability

CVE-2025-23594 Overview

CVE-2025-23594 is a reflected Cross-Site Scripting (XSS) vulnerability in the Uzzal Mondal Google Map With Fancybox WordPress plugin (location-piker). The flaw stems from improper neutralization of input during web page generation [CWE-79]. All versions up to and including 2.1.0 are affected.

An attacker can craft a malicious URL that, when clicked by an authenticated or unauthenticated user, executes arbitrary JavaScript in the victim's browser session. The vulnerability requires user interaction and operates over the network without authentication.

Critical Impact
Successful exploitation allows attackers to execute arbitrary JavaScript in a victim's browser, enabling session theft, credential harvesting, and unauthorized actions in the WordPress site context.

Affected Products

Uzzal Mondal Google Map With Fancybox (location-piker) plugin for WordPress
All versions from initial release through 2.1.0
WordPress sites with the plugin installed and active

Technical Details for CVE-2025-23594

Vulnerability Analysis

The vulnerability is a reflected XSS issue classified under [CWE-79]: Improper Neutralization of Input During Web Page Generation. The Google Map With Fancybox plugin reflects user-supplied input back into HTTP responses without proper sanitization or output encoding.

When a victim clicks a crafted link, the malicious payload is reflected into the rendered page and executes in the browser. The scope is changed, meaning the injected script can affect resources beyond the vulnerable component itself. Confidentiality, integrity, and availability impacts are each rated low individually, but the combination enables session hijacking and content manipulation.

Root Cause

The plugin fails to apply proper input validation and output escaping to one or more request parameters. WordPress provides sanitization functions such as esc_html(), esc_attr(), and sanitize_text_field(), but the affected code paths do not invoke them before echoing user-controlled data into HTML context.

Attack Vector

The attack vector is network-based and requires user interaction. An attacker crafts a URL containing a JavaScript payload in a vulnerable parameter and delivers it through phishing, forum posts, or malicious advertisements. When the victim visits the link, the script executes in the context of the WordPress site.

No code examples are publicly verified for this vulnerability. Refer to the Patchstack WordPress Vulnerability Report for additional technical context.

Detection Methods for CVE-2025-23594

Indicators of Compromise

HTTP GET requests to WordPress endpoints containing URL-encoded <script> tags, javascript: URIs, or event handler attributes such as onerror= and onload=
Referrer logs showing external sites linking to plugin URLs with suspicious query parameters
Unexpected outbound requests from authenticated administrator browsers to attacker-controlled domains

Detection Strategies

Inspect web server access logs for requests targeting location-piker plugin paths with encoded script payloads
Deploy a Web Application Firewall (WAF) with rules to identify reflected XSS patterns in query strings and POST bodies
Review WordPress audit logs for anomalous administrative actions originating from legitimate user sessions

Monitoring Recommendations

Enable Content Security Policy (CSP) reporting to capture script execution attempts that violate policy
Monitor for the presence of vulnerable plugin versions across managed WordPress fleets
Alert on outbound HTTP requests from WordPress admin sessions to unfamiliar external hosts

How to Mitigate CVE-2025-23594

Immediate Actions Required

Identify all WordPress installations running the Google Map With Fancybox plugin version 2.1.0 or earlier
Deactivate and remove the plugin if no patched version is available
Rotate administrator credentials and invalidate active sessions if exploitation is suspected

Patch Information

At the time of publication, no fixed version is referenced in the NVD record. Affected versions extend through 2.1.0. Administrators should consult the Patchstack advisory and the WordPress plugin repository for updated release information.

Workarounds

Remove the location-piker plugin until a patched release is published
Deploy WAF rules that block requests containing script tags or JavaScript event handlers in query parameters
Implement a strict Content Security Policy that disallows inline scripts and restricts script sources to trusted origins
Train administrators to avoid clicking unsolicited links targeting their WordPress sites

bash

# Example WAF rule pattern (ModSecurity-style) to block reflected XSS payloads
SecRule ARGS "@rx (?i)(<script|javascript:|onerror=|onload=)" \
    "id:1009001,phase:2,deny,status:403,msg:'Reflected XSS attempt blocked'"
