CVE-2026-23958
📋 TL;DR
Dataease versions before 2.10.19 use MD5-hashed passwords as JWT signing secrets, allowing attackers to brute-force admin passwords via unmonitored API endpoints. This vulnerability affects all Dataease deployments using vulnerable versions. Successful exploitation could lead to complete system compromise.
💻 Affected Systems
- Dataease
📦 What is this software?
Dataease by Dataease
⚠️ Risk & Real-World Impact
Worst Case
Full administrative takeover of Dataease instance, allowing data exfiltration, system manipulation, and potential lateral movement to connected systems.
Likely Case
Unauthorized admin access leading to data theft, configuration changes, and privilege escalation within the Dataease environment.
If Mitigated
Limited impact if strong password policies and network segmentation prevent brute-force attempts.
🎯 Exploit Status
Exploitation requires access to JWT tokens and ability to brute-force MD5 hashes, which is computationally inexpensive.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.10.19
Vendor Advisory: https://github.com/dataease/dataease/security/advisories/GHSA-5wvm-4m4q-rh7j
Restart Required: Yes
Instructions:
1. Backup current Dataease installation and data. 2. Download version 2.10.19 from official repository. 3. Stop Dataease service. 4. Replace installation with new version. 5. Restart Dataease service. 6. Verify functionality.
🧯 If You Can't Patch
- Implement strict network access controls to limit API endpoint exposure
- Enforce strong password policies and monitor for brute-force attempts
🔍 How to Verify
Check if Vulnerable:
Check Dataease version via web interface or configuration files; versions below 2.10.19 are vulnerable.Check Version:
Check Dataease web interface admin panel or review application configuration files for version information.Verify Fix Applied:
Confirm version is 2.10.19 or higher and test JWT token generation/validation functionality.📡 Detection & Monitoring
Log Indicators:
- Multiple failed authentication attempts
- Unusual API endpoint access patterns
