CVE-2025-49065: Visit Counter Stored XSS Vulnerability

CVE-2025-49065 is a stored cross-site scripting flaw in the Visit Counter WordPress plugin that allows attackers to inject malicious scripts. This article covers technical details, affected versions, security impact, and mitigation.

Published: April 22, 2026

CVE-2025-49065 Overview

CVE-2025-49065 is a Stored Cross-Site Scripting (XSS) vulnerability affecting the Visit Counter WordPress plugin developed by BestiaDurmiente. This vulnerability arises from improper neutralization of input during web page generation, allowing attackers to inject malicious scripts that persist in the application and execute when other users access affected pages.

Critical Impact

Attackers can inject persistent malicious scripts into the Visit Counter plugin, potentially compromising website administrators and visitors through session hijacking, credential theft, or malware distribution.

Affected Products

  • WordPress Visit Counter plugin version 1.0 and earlier
  • All WordPress installations using the vulnerable Visit Counter (visit-counter) plugin

Discovery Timeline

  • 2025-08-14 - CVE-2025-49065 published to NVD
  • 2026-04-15 - Last updated in NVD database

Technical Details for CVE-2025-49065

Vulnerability Analysis

This vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation), commonly known as Cross-Site Scripting. The Stored XSS variant is particularly dangerous because malicious payloads are permanently stored in the application's database and served to all users who view the affected content.

The Visit Counter plugin fails to properly sanitize and encode user-supplied input before storing it in the database and rendering it on web pages. This allows an attacker to inject JavaScript code that will execute in the browser context of any user viewing the affected page, including site administrators.

Root Cause

The root cause of this vulnerability is insufficient input validation and output encoding within the Visit Counter plugin. The plugin does not properly sanitize user-controlled data before storing it in the WordPress database, nor does it escape this data when rendering it in HTML output. This failure to implement proper input/output handling allows malicious scripts to be injected and executed.

Attack Vector

The attack vector for this Stored XSS vulnerability involves an attacker submitting malicious JavaScript code through input fields processed by the Visit Counter plugin. Once stored, the malicious payload executes automatically when legitimate users, including administrators, view pages containing the injected content.

Successful exploitation could enable attackers to:

  • Steal session cookies and authentication tokens
  • Perform actions on behalf of authenticated users
  • Redirect users to malicious websites
  • Deface website content
  • Deploy keyloggers or other malicious scripts

For detailed technical information about this vulnerability, refer to the Patchstack Vulnerability Report.

Detection Methods for CVE-2025-49065

Indicators of Compromise

  • Unexpected JavaScript code or <script> tags in database entries related to the Visit Counter plugin
  • Anomalous network requests originating from visitors' browsers to external domains
  • Reports from users about unexpected redirects or browser behavior when visiting your WordPress site
  • Unusual entries in web server access logs showing encoded script payloads

Detection Strategies

  • Implement Web Application Firewall (WAF) rules to detect and block common XSS payloads in HTTP requests
  • Deploy Content Security Policy (CSP) headers to restrict inline script execution and report policy violations
  • Regularly audit WordPress database tables associated with the Visit Counter plugin for suspicious content
  • Monitor browser console errors and CSP violation reports for signs of blocked malicious scripts

Monitoring Recommendations

  • Enable detailed logging for all WordPress plugin activity and user interactions
  • Configure real-time alerting for Content Security Policy violations
  • Implement integrity monitoring for plugin files and database content
  • Use SentinelOne's endpoint detection capabilities to identify browser-based attacks and suspicious script execution

How to Mitigate CVE-2025-49065

Immediate Actions Required

  • Deactivate and remove the Visit Counter plugin (visit-counter) from your WordPress installation immediately
  • Audit your WordPress database for any injected malicious content that may have been stored
  • Review web server access logs for evidence of exploitation attempts
  • Consider implementing a Web Application Firewall with XSS protection rules

Patch Information

At the time of publication, no patched version of the Visit Counter plugin is available. The vulnerability affects all versions through 1.0. Organizations should remove the plugin and seek alternative visitor counting solutions that are actively maintained and follow secure coding practices.

For the latest information, refer to the Patchstack Vulnerability Report.

Workarounds

  • Remove the Visit Counter plugin entirely from your WordPress installation until a security patch is released
  • Implement strict Content Security Policy headers to mitigate the impact of any stored XSS payloads
  • Use WordPress security plugins that provide input sanitization and XSS protection at the application level
  • Restrict access to the WordPress admin panel to trusted IP addresses only
bash
# Add Content Security Policy header to Apache configuration
# Add to .htaccess or Apache virtual host configuration
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; frame-ancestors 'self';"

# For Nginx, add to server block
# add_header Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; frame-ancestors 'self';";
