CVE-2026-3221
📋 TL;DR
Devolutions Server versions 2025.3.14 and earlier store sensitive user account information unencrypted in the database. This allows attackers with database access to read sensitive user data directly. Organizations using affected Devolutions Server versions are vulnerable.
💻 Affected Systems
- Devolutions Server
📦 What is this software?
Devolutions Server by Devolutions
⚠️ Risk & Real-World Impact
Worst Case
Attackers gain full database access and exfiltrate all user account information including credentials, personal data, and authentication details, leading to complete account compromise and potential lateral movement.
Likely Case
Attackers with database access (through compromised credentials, misconfigurations, or insider threats) extract sensitive user information for credential reuse, identity theft, or targeted attacks.
If Mitigated
With proper database access controls, network segmentation, and monitoring, the impact is limited to authorized database administrators only.
🎯 Exploit Status
Exploitation requires database access credentials or physical access to database files. No special tools needed - standard database clients can read the unencrypted data.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2025.3.15 or later
Vendor Advisory: https://devolutions.net/security/advisories/DEVO-2026-0004/
Restart Required: Yes

🔧 Temporary Workarounds
Database Encryption Implementation
allImplement database-level encryption (TDE) or application-level encryption for sensitive fields
Restrict Database Access
allImplement strict access controls, network segmentation, and monitoring for database access
🧯 If You Can't Patch
- Implement database encryption at rest using database-native features
- Restrict database access to only necessary personnel and systems using firewall rules and authentication
🔍 How to Verify
Check if Vulnerable:
Check Devolutions Server version in web interface or via 'About' section. If version is 2025.3.14 or earlier, system is vulnerable.Check Version:
Check web interface or server logs for version informationVerify Fix Applied:
After patching, verify version is 2025.3.15 or later. Check that user data in database appears encrypted or hashed.📡 Detection & Monitoring
Log Indicators:
- Unusual database access patterns
- Multiple failed login attempts to database
- Large data export operations
Network Indicators:
- Unusual database port connections from unauthorized IPs
- Large outbound data transfers from database server
SIEM Query:
source="database_logs" AND (event_type="data_access" OR event_type="export") AND user NOT IN ("authorized_users")
