CVE-2025-11442
📋 TL;DR
This CVE describes a cross-site request forgery (CSRF) vulnerability in JhumanJ OpnForm API endpoints up to version 1.9.3. The vulnerability could allow attackers to perform unauthorized actions if they obtain valid JWT tokens through other means like XSS. Only OpnForm installations up to version 1.9.3 are affected.
💻 Affected Systems
- JhumanJ OpnForm
📦 What is this software?
Opnform by Jhumanj
⚠️ Risk & Real-World Impact
Worst Case
An attacker with a stolen JWT token could perform unauthorized API operations, potentially modifying forms, accessing form submissions, or altering application configuration.
Likely Case
Limited impact since the vendor states API requires authentication via Bearer tokens and XSS vectors are mitigated, making initial token theft difficult.
If Mitigated
With proper authentication controls and no XSS vulnerabilities, the CSRF vulnerability has minimal practical impact.
🎯 Exploit Status
Exploitation requires a valid JWT token, which the vendor states is protected against XSS theft. The exploit has been released publicly but requires token acquisition first.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version 1.9.4 or later
Vendor Advisory: https://docs.google.com/document/d/1GUjJA9vUbsXUngAv6ySsbCIhVynf8_djardLZYEDOe0/edit
Restart Required: No
Instructions:
1. Backup your OpnForm installation and database. 2. Update to OpnForm version 1.9.4 or later. 3. Verify the update completed successfully.
🔧 Temporary Workarounds
Implement CSRF tokens for API endpoints
allAdd CSRF token validation to all API endpoints that accept state-changing requests
Enforce SameSite cookies
allConfigure session cookies with SameSite=Strict attribute to prevent CSRF attacks
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to detect and block CSRF patterns
- Monitor for unusual API activity and implement rate limiting on sensitive endpoints
🔍 How to Verify
Check if Vulnerable:
Check OpnForm version in admin panel or via package manager. If version is 1.9.3 or earlier, the system is vulnerable.Check Version:
Check OpnForm admin dashboard or run: php artisan --version (for Laravel-based installations)Verify Fix Applied:
Verify OpnForm version is 1.9.4 or later. Test API endpoints to ensure CSRF protection is implemented.📡 Detection & Monitoring
Log Indicators:
- Multiple failed API requests with valid tokens
- Unusual API call patterns from single tokens
- API requests missing expected CSRF headers
Network Indicators:
- Cross-origin API requests without proper CORS headers
- API requests with stolen JWT tokens
SIEM Query:
source="opnform_logs" AND (http_method="POST" OR http_method="PUT" OR http_method="DELETE") AND NOT csrf_token=* AND response_code=200🔗 References
