CVE-2026-1707
📋 TL;DR
pgAdmin 9.11 in server mode has a restore restriction bypass vulnerability that allows authenticated attackers to execute arbitrary commands on the host system during restore operations. Attackers can observe active restores, extract restriction keys, and race the process to inject malicious meta-commands. This affects organizations using pgAdmin's web interface for PostgreSQL database management.
💻 Affected Systems
- pgAdmin
📦 What is this software?
Pgadmin 4 by Pgadmin
⚠️ Risk & Real-World Impact
Worst Case
Full compromise of the pgAdmin host system leading to database credential theft, lateral movement, and persistent backdoor installation.
Likely Case
Unauthorized command execution on the pgAdmin server, potentially allowing database access, file system manipulation, or privilege escalation.
If Mitigated
Limited impact if proper network segmentation, authentication controls, and monitoring prevent unauthorized access to the web interface.
🎯 Exploit Status
Exploitation requires authenticated access to pgAdmin web interface, timing precision for race condition, and understanding of pgAdmin restore processes.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check GitHub issue for specific fixed version
Vendor Advisory: https://github.com/pgadmin-org/pgadmin4/issues/9518
Restart Required: Yes
Instructions:
1. Check current pgAdmin version
2. Update to patched version from official pgAdmin releases
3. Restart pgAdmin service
4. Verify fix by testing restore operations
🔧 Temporary Workarounds
Disable Server Mode Restores
allPrevent restore operations through the web interface entirely
Configure pgAdmin to only allow local restores or disable restore functionality in server mode
Network Segmentation
allRestrict access to pgAdmin web interface to trusted networks only
Configure firewall rules to limit pgAdmin port access to specific IP ranges
🧯 If You Can't Patch
- Implement strict authentication and authorization controls for pgAdmin access
- Monitor and audit all restore operations for suspicious activity
🔍 How to Verify
Check if Vulnerable:
Check if running pgAdmin 9.11 in server mode with web interface accessibleCheck Version:
pgadmin4 --version or check pgAdmin web interface about pageVerify Fix Applied:
Verify pgAdmin version is updated beyond 9.11 and test restore operations📡 Detection & Monitoring
Log Indicators:
- Multiple rapid restore attempts
- Unusual meta-command usage in restore logs
- Failed authentication attempts followed by restore operations
Network Indicators:
- Unusual traffic patterns to pgAdmin web interface during restore operations
- Multiple concurrent connections to restore endpoints
