Dataease by Dataease
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary commands, steal data, deploy ransomware, or pivot to other systems in the network.
Likely Case
Attackers upload malicious plugins to execute code, potentially creating backdoors, mining cryptocurrency, or exfiltrating sensitive data from the Dataease instance.
If Mitigated
With proper network segmentation and access controls, impact could be limited to the Dataease application server only.
🎯 Exploit Status
The GitHub issue shows exploitation details. Attackers can craft malicious plugin files and upload them without authentication.

🔧 Temporary Workarounds
Disable plugin upload endpoint
allBlock access to the vulnerable /api/plugin/upload endpoint
# Add to web server config (nginx example):
location /api/plugin/upload { deny all; }
Network access control
linuxRestrict access to Dataease administration interface
# Firewall rule example:
iptables -A INPUT -p tcp --dport [Dataease-port] -s [trusted-ips] -j ACCEPT
iptables -A INPUT -p tcp --dport [Dataease-port] -j DROP
🧯 If You Can't Patch
- Immediately restrict network access to Dataease to only trusted IP addresses
- Implement WAF rules to block requests to /api/plugin/upload endpoint
🔍 How to Verify
Check if Vulnerable:
Check if running Dataease v1.11.1 and if /api/plugin/upload endpoint is accessibleCheck Version:
Check Dataease web interface admin panel or application logs for version informationVerify Fix Applied:
Verify version is v1.11.2 or later and test that plugin uploads are properly validated📡 Detection & Monitoring
