CVE-2025-58690: Doliconnect CSRF Vulnerability

CVE-2025-58690 Overview

A Cross-Site Request Forgery (CSRF) vulnerability has been identified in the ptibogxiv Doliconnect WordPress plugin that enables attackers to perform Stored Cross-Site Scripting (XSS) attacks. This chained vulnerability allows malicious actors to force authenticated users to unknowingly submit requests that inject persistent malicious scripts into the application, affecting all subsequent users who view the compromised content.

Critical Impact

Attackers can leverage CSRF to inject persistent XSS payloads, potentially leading to session hijacking, credential theft, and unauthorized actions performed on behalf of legitimate users across the WordPress installation.

Affected Products

• Doliconnect WordPress Plugin versions through 9.5.7
• WordPress installations with Doliconnect plugin enabled
• Dolibarr ERP/CRM integrations using Doliconnect connector

Technical Details for CVE-2025-58690

Vulnerability Analysis

This vulnerability represents a dangerous combination of two distinct web security flaws: Cross-Site Request Forgery (CWE-352) and Stored Cross-Site Scripting. The CSRF component allows attackers to craft malicious requests that, when executed by an authenticated user, bypass the application's origin validation mechanisms. When combined with the absence of proper input sanitization, this enables the injection of persistent JavaScript payloads that are stored in the database and served to all users accessing the affected pages.

The attack requires user interaction—specifically, an authenticated administrator or privileged user must be tricked into visiting a malicious page or clicking a crafted link while logged into WordPress. The scope change indicated in the vulnerability characteristics means that successful exploitation can impact resources beyond the vulnerable component itself, potentially affecting the entire WordPress installation and connected Dolibarr ERP system.

Root Cause

The root cause of this vulnerability lies in two security control failures within the Doliconnect plugin:

1. Missing CSRF Token Validation: The plugin fails to implement or properly verify nonce tokens on state-changing requests, allowing cross-origin requests to be processed without validation of the request origin.

2. Insufficient Output Encoding: User-supplied input is stored and subsequently rendered without proper HTML entity encoding or context-aware output escaping, enabling persistent script injection.

These combined weaknesses allow an attacker to chain CSRF into a Stored XSS attack, where the malicious payload persists in the WordPress database and executes in the browsers of all users who view the affected content.

Attack Vector

The attack is conducted over the network and requires user interaction to succeed. An attacker would typically:

1. Craft a malicious HTML page or email containing a hidden form or JavaScript that automatically submits a request to the vulnerable Doliconnect endpoint
2. Embed XSS payload (malicious JavaScript) within the forged request parameters
3. Trick an authenticated WordPress administrator into visiting the malicious page
4. The forged request executes with the victim's session, storing the XSS payload
5. The persistent XSS payload then executes for any user viewing the affected content, enabling session theft, keylogging, or further malicious actions

The vulnerability can be exploited without authentication on the attacker's side, though it requires an authenticated victim to trigger the CSRF. The malicious script injection occurs through form fields or parameters that lack proper sanitization before being stored and displayed.

Detection Methods for CVE-2025-58690

Indicators of Compromise

• Unexpected JavaScript code or <script> tags appearing in Doliconnect plugin data or WordPress database entries
• HTTP Referer headers showing requests to Doliconnect endpoints originating from external or unknown domains
• Anomalous POST requests to plugin endpoints missing valid WordPress nonce tokens
• User session tokens or cookies being sent to external domains in network logs

Detection Strategies

• Monitor web application logs for POST requests to Doliconnect plugin endpoints lacking _wpnonce parameters or containing invalid nonces
• Implement Content Security Policy (CSP) headers to detect and block inline script execution attempts
• Deploy Web Application Firewall (WAF) rules to identify and block CSRF attack patterns and XSS payloads
• Review WordPress database tables associated with Doliconnect for stored HTML/JavaScript content that appears malicious

Monitoring Recommendations

• Enable detailed logging for all WordPress plugin administrative actions and form submissions
• Configure browser console monitoring for CSP violation reports indicating XSS execution attempts
• Implement anomaly detection for unusual patterns in user activity following visits to external links
• Establish baseline behavior for Doliconnect plugin API calls to identify deviations

How to Mitigate CVE-2025-58690

Immediate Actions Required

• Update the Doliconnect plugin to a patched version when available from the developer
• Temporarily disable the Doliconnect plugin if updates are not yet available and the functionality is non-critical
• Review WordPress database entries related to Doliconnect for any injected malicious content
• Audit user sessions and force password resets for any accounts that may have been compromised
• Implement additional WAF rules to block CSRF and XSS attack patterns targeting the plugin

Patch Information

At the time of this advisory, users should monitor the Patchstack WordPress Vulnerability database for updated patch information from the plugin developer. The vulnerability affects Doliconnect versions through 9.5.7, and users should upgrade to a newer patched version as soon as one becomes available.

Workarounds

• Restrict access to the WordPress administrative interface to trusted IP addresses only using .htaccess or server-level firewall rules
• Implement strict Content Security Policy headers to prevent inline script execution: Content-Security-Policy: script-src 'self'
• Train administrative users to avoid clicking untrusted links or visiting unknown websites while authenticated to WordPress
• Consider using a browser extension or separate browser profile for WordPress administration to reduce CSRF risk

# Example Apache .htaccess configuration to restrict admin access
<Files wp-login.php>
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
</Files>

# Example Content Security Policy header
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline';"
