CVE-2025-28062
📋 TL;DR
A Cross-Site Request Forgery vulnerability in ERPNEXT allows attackers to trick authenticated users into performing unauthorized actions like deleting users, resetting passwords, or escalating privileges. This affects ERPNEXT versions 14.82.1 and 14.74.3 where CSRF protections are missing. Any organization using these vulnerable versions is at risk.

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through admin account takeover, data destruction via mass user deletion, and privilege escalation granting attackers full administrative control.
Likely Case
Targeted attacks against specific users to reset passwords, delete accounts, or modify permissions, leading to business disruption and potential data loss.
If Mitigated
Limited impact with proper CSRF protections, session management, and user awareness reducing successful exploitation attempts.
🎯 Exploit Status
Exploitation requires tricking an authenticated user into visiting a malicious page. Public proof-of-concept code is available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check latest ERPNEXT releases after 14.82.1 and 14.74.3
Vendor Advisory: https://github.com/frappe/erpnext
Restart Required: Yes
Instructions:
1. Backup your ERPNEXT instance and database. 2. Update ERPNEXT to the latest patched version via the bench update command. 3. Restart the ERPNEXT services. 4. Verify the update was successful.
🔧 Temporary Workarounds
Implement CSRF Tokens
allManually add CSRF token validation to vulnerable endpoints
Requires code modification - consult ERPNEXT documentation for CSRF implementation
Use SameSite Cookies
allConfigure session cookies with SameSite=Strict attribute
Set session.cookie.samesite = 'Strict' in your ERPNEXT configuration
🧯 If You Can't Patch
- Implement web application firewall rules to detect and block CSRF attempts
- Enforce strict session management with short timeouts and re-authentication for sensitive actions
🔍 How to Verify
Check if Vulnerable:
Check your ERPNEXT version. If it's 14.82.1 or 14.74.3, you are vulnerable.Check Version:
bench versionVerify Fix Applied:
After updating, test CSRF protection by attempting to perform actions without proper tokens.📡 Detection & Monitoring
Log Indicators:
- Multiple failed authentication attempts followed by successful sensitive actions
- Unusual user deletion or permission change patterns
Network Indicators:
- Requests to sensitive endpoints without Referer headers or CSRF tokens
- Multiple POST requests from same IP to different user accounts
