CVE-2026-1195
📋 TL;DR
This vulnerability in MineAdmin's JWT token refresh function allows attackers to bypass authentication by manipulating insufficiently verified data. It affects all MineAdmin 1.x and 2.x installations, enabling potential unauthorized access to administrative functions. The attack can be performed remotely but requires high complexity to execute successfully.
💻 Affected Systems
- MineAdmin
📦 What is this software?
Mineadmin by Mineadmin
Mineadmin by Mineadmin
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through privilege escalation, allowing attackers to gain administrative access, modify system configurations, and potentially execute arbitrary code.
Likely Case
Unauthorized access to administrative functions, data leakage, and potential manipulation of system settings without proper authentication.
If Mitigated
Limited impact with proper network segmentation, strong authentication controls, and monitoring in place to detect anomalous token refresh attempts.
🎯 Exploit Status
Exploit code is publicly available but requires understanding of JWT manipulation and the specific MineAdmin implementation. Attack complexity is rated as high.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: None - vendor did not respond to disclosure
Restart Required: No
Instructions:
No official patch available. Consider upgrading to a non-vulnerable version if available, or implement workarounds.
🔧 Temporary Workarounds
Disable vulnerable endpoint
allTemporarily disable or restrict access to the /system/refresh endpoint that handles JWT token refresh functionality
# Configure web server (nginx example) to block /system/refresh
location /system/refresh { deny all; }
# Configure firewall to block access to refresh endpoint
Implement additional JWT validation
allAdd custom validation logic to verify JWT token authenticity beyond the vulnerable refresh function
# Custom middleware or validation function required
# Implementation depends on MineAdmin framework specifics
🧯 If You Can't Patch
- Implement strict network access controls to limit who can access the MineAdmin interface
- Deploy a Web Application Firewall (WAF) with rules to detect and block JWT manipulation attempts
🔍 How to Verify
Check if Vulnerable:
Check if your MineAdmin installation is version 1.x or 2.x and has the /system/refresh endpoint accessible
Check Version:
# Check MineAdmin version in configuration files or admin interface
# Typically in config files or via admin panel
Verify Fix Applied:
Test if JWT token refresh functionality properly validates token authenticity and rejects manipulated tokens
📡 Detection & Monitoring
Log Indicators:
- Multiple failed JWT refresh attempts
- Unusual token refresh patterns from unexpected IPs
- Access to /system/refresh endpoint with malformed tokens
Network Indicators:
- Unusual traffic to /system/refresh endpoint
- HTTP requests with manipulated JWT tokens in headers
