CVE-2025-31460: OmniLeads Scripts & Tags Manager CSRF

CVE-2025-31460 Overview

CVE-2025-31460 is a Cross-Site Request Forgery (CSRF) vulnerability in the OmniLeads Scripts and Tags Manager WordPress plugin developed by danielmuldernl. This vulnerability allows attackers to chain CSRF with Stored Cross-Site Scripting (XSS), enabling malicious actors to inject persistent scripts into the WordPress site by tricking authenticated administrators into performing unintended actions.

The vulnerability arises from insufficient CSRF token validation in plugin functionality that handles script and tag management operations. When exploited, an attacker can craft malicious requests that, when executed by an authenticated administrator, result in the storage of malicious JavaScript code within the WordPress database.

Critical Impact

Attackers can leverage this CSRF to Stored XSS chain to execute arbitrary JavaScript in the context of any user visiting affected pages, potentially leading to session hijacking, credential theft, administrative account compromise, or further site defacement.

Affected Products

• OmniLeads Scripts and Tags Manager plugin version 1.3 and earlier
• WordPress installations running the vulnerable plugin versions
• All sites where the plugin is actively managing scripts and tags

Technical Details for CVE-2025-31460

Vulnerability Analysis

This vulnerability represents a chained attack scenario combining two distinct web application weaknesses: CSRF and Stored XSS. The OmniLeads Scripts and Tags Manager plugin fails to implement proper CSRF protection on administrative functions that handle script and tag content storage.

The attack flow begins when an attacker crafts a malicious webpage or email containing a hidden form or request targeting the vulnerable plugin endpoint. When an authenticated WordPress administrator visits the attacker-controlled page, their browser automatically sends the malicious request with their active session credentials. Because the plugin does not validate the authenticity of the request origin, the malicious payload—containing JavaScript code—is stored in the WordPress database.

Once stored, the malicious script executes whenever any user (including administrators) accesses pages where the injected scripts are rendered. This persistence makes the attack particularly dangerous as it can affect all site visitors without requiring further interaction from the attacker.

Root Cause

The root cause of this vulnerability is the absence or improper implementation of CSRF nonce verification in the plugin's script and tag management functionality. WordPress provides built-in nonce functions (wp_nonce_field() and wp_verify_nonce()) specifically to prevent CSRF attacks, but the vulnerable plugin versions fail to utilize these protections adequately.

Additionally, the plugin does not properly sanitize or escape user-supplied input before storing it in the database, allowing the injection of malicious script content that constitutes the Stored XSS component of this vulnerability chain.

Attack Vector

The attack requires social engineering to trick an authenticated WordPress administrator into visiting an attacker-controlled webpage while logged into their WordPress dashboard. The attack page contains a hidden form that automatically submits a request to the vulnerable plugin endpoint.

The malicious payload typically contains JavaScript code designed to steal session cookies, capture keystrokes, redirect users to phishing pages, or create additional administrator accounts. Since the XSS is stored rather than reflected, the impact persists across multiple page loads and affects all users who view the compromised pages.

The attack chain proceeds as follows: First, the attacker prepares a malicious webpage with an auto-submitting form targeting the plugin's script management endpoint. Second, the administrator visits this page while authenticated to WordPress. Third, the CSRF request succeeds due to missing nonce validation. Finally, the XSS payload is stored and executes on subsequent page views.

Detection Methods for CVE-2025-31460

Indicators of Compromise

• Unexpected or unfamiliar JavaScript code appearing in the plugin's script management settings
• New administrator accounts created without authorization
• Reports of browser security warnings or suspicious redirects from site visitors
• Unusual outbound network connections to unknown domains from client browsers

Detection Strategies

• Review WordPress plugin settings for the OmniLeads Scripts and Tags Manager to identify any unauthorized script entries
• Audit database tables associated with the plugin for malicious JavaScript payloads such as <script> tags or event handlers
• Monitor WordPress administrator session activity for unusual patterns or geographic anomalies
• Implement Content Security Policy (CSP) headers to detect and block unauthorized inline script execution

Monitoring Recommendations

• Enable WordPress audit logging to track all administrative actions within plugin settings
• Configure web application firewall (WAF) rules to alert on suspicious POST requests to plugin endpoints
• Set up file integrity monitoring for WordPress core files and plugin directories
• Monitor browser console errors on front-end pages that may indicate blocked or failed XSS attempts

How to Mitigate CVE-2025-31460

Immediate Actions Required

• Deactivate and remove the OmniLeads Scripts and Tags Manager plugin if version 1.3 or earlier is installed
• Audit all scripts and tags currently configured in the plugin for malicious content before any data migration
• Review WordPress user accounts for any unauthorized administrator accounts that may have been created
• Clear browser caches and invalidate all active WordPress sessions to remove potentially compromised session data

Patch Information

At the time of publication, no patched version of the OmniLeads Scripts and Tags Manager plugin has been identified in the available vulnerability data. Organizations should monitor the Patchstack Vulnerability Report for updates on available fixes or consider migrating to an alternative plugin that provides similar functionality with proper security controls.

Workarounds

• Remove the vulnerable plugin entirely and migrate to an alternative scripts and tags management solution
• Implement a Web Application Firewall (WAF) with rules to block CSRF and XSS attack patterns targeting WordPress plugins
• Restrict administrative access to the WordPress dashboard by IP address to limit the attack surface
• Use browser extensions or security policies that prevent automatic form submissions on untrusted sites

# Disable the plugin via WP-CLI
