CVE-2025-25132: Visitor Details Plugin Stored XSS Flaw

CVE-2025-25132 Overview

CVE-2025-25132 is a stored Cross-Site Scripting (XSS) vulnerability in the ravi Singh Visitor Details WordPress plugin (visitors-details). The flaw affects all plugin versions up to and including 1.0.1. Attackers can inject persistent JavaScript payloads that execute in the browsers of users who view the affected pages. The issue is tracked under [CWE-79], Improper Neutralization of Input During Web Page Generation.

The vulnerability is network-exploitable, requires no privileges, and depends on user interaction. Successful exploitation crosses a security scope boundary, enabling theft of session tokens, redirection to malicious infrastructure, or unauthorized actions performed on behalf of the victim.

Critical Impact
Unauthenticated attackers can store malicious scripts that execute against any user, including administrators, viewing the affected pages.

Affected Products

ravi Singh Visitor Details WordPress plugin (visitors-details)
Visitor Details versions through 1.0.1
WordPress sites with the plugin installed and activated

Technical Details for CVE-2025-25132

Vulnerability Analysis

The Visitor Details plugin fails to neutralize user-supplied input before rendering it in HTML output. Attacker-controlled data is stored in the WordPress database and later reflected onto pages without proper output encoding. When a victim loads an affected page, the browser parses the injected payload as executable script.

The vulnerability requires user interaction, meaning a victim must visit a page containing the stored payload. Because the impacted scope changes (S:C), code executing in the browser context affects components beyond the vulnerable plugin, including the broader WordPress administrative session.

EPSS data places the probability of exploitation activity at 0.232% with a percentile of 45.847, reflecting limited observed targeting at the time of analysis.

Root Cause

The plugin does not apply WordPress sanitization helpers such as sanitize_text_field() on input or escaping helpers such as esc_html(), esc_attr(), or wp_kses_post() on output. Input flows from form submission to persistent storage and back to rendered HTML without filtering, satisfying the conditions for stored XSS.

Attack Vector

An unauthenticated attacker submits a payload containing HTML and JavaScript through an input field exposed by the plugin. The payload persists in the database. When a logged-in administrator or other user opens a page that displays the stored content, the script executes with their privileges. Common follow-on actions include cookie exfiltration, CSRF against admin endpoints to create new administrators, and serving drive-by downloads.

The vulnerability mechanism is described in the Patchstack Vulnerability Advisory. No verified public proof-of-concept code is available.

Detection Methods for CVE-2025-25132

Indicators of Compromise

Database rows in plugin tables containing <script>, javascript:, onerror=, or onload= substrings
Unexpected outbound requests from administrator browsers to attacker-controlled domains
New WordPress administrator accounts created without an audit trail
Modified theme or plugin files following an administrator session

Detection Strategies

Audit wp_options and plugin-specific tables for HTML or script tags in stored fields
Inspect web server access logs for POST requests to plugin endpoints carrying script payloads
Deploy Content Security Policy (CSP) violation reporting to surface inline script execution
Review browser console errors and CSP reports across administrator workstations

Monitoring Recommendations

Alert on creation of new WordPress administrators or privilege changes
Monitor for outbound HTTP requests to uncategorized domains from admin browser sessions
Track plugin file integrity and changes to active themes
Enable WordPress audit logging for content edits performed under admin sessions

How to Mitigate CVE-2025-25132

Immediate Actions Required

Deactivate and remove the Visitor Details plugin until a patched release is available
Audit existing plugin data for stored payloads and purge malicious entries
Force password resets and invalidate active sessions for all WordPress administrators
Review user accounts and remove any unauthorized administrator additions

Patch Information

No fixed version is identified in the available advisory data; all releases through 1.0.1 are affected. Site operators should monitor the Patchstack Vulnerability Advisory for vendor updates and replace the plugin with a maintained alternative if a patch does not become available.

Workarounds

Place a Web Application Firewall (WAF) rule in front of WordPress to block script tags in plugin endpoints
Apply a strict Content Security Policy that disallows inline scripts and unknown origins
Restrict access to admin pages by IP allow-listing where feasible
Use Patchstack or equivalent virtual patching to mitigate the input vector until removal

bash

# Example WAF rule pattern (ModSecurity) to block script payloads to plugin endpoints
SecRule REQUEST_URI "@contains /wp-content/plugins/visitors-details/" \
  "id:1002513,phase:2,deny,status:403,t:lowercase,\
   chain,msg:'Block stored XSS payload to Visitor Details plugin'"
  SecRule ARGS "@rx (?i)(<script|javascript:|onerror=|onload=)" "t:none"
