⚠️ Risk & Real-World Impact
Worst Case
Database credentials are exposed in logs, leading to unauthorized database access, data theft, or system compromise.
Likely Case
Database passwords are visible in log files, potentially exposing them to administrators or attackers with log access.
If Mitigated
If logs are properly secured and access-controlled, the exposed passwords remain protected.
🎯 Exploit Status
Exploitation requires access to log files containing the exposed password.
🛠️ Fix & Mitigation

Patch Version: 0.4.0rc3 and later
Vendor Advisory: https://github.com/llamastack/llama-stack/pull/4439
Restart Required: Yes
Instructions:
1. Update Llama Stack to version 0.4.0rc3 or later. 2. Restart the Llama Stack service. 3. Verify the fix by checking logs for password exposure.
🔧 Temporary Workarounds
Secure Log Files
linuxRestrict access to log files containing initialization logs.
chmod 600 /path/to/llama-stack/logs/*
chown root:root /path/to/llama-stack/logs/*
Disable Debug Logging
allReduce logging verbosity to prevent sensitive information exposure.
Set log_level to 'WARNING' or higher in configuration
🧯 If You Can't Patch
- Rotate pgvector database passwords immediately.
- Implement strict access controls on log storage and viewing.
🔍 How to Verify
Check if Vulnerable:
Check initialization logs for exposed pgvector passwords. Look for log entries containing database connection strings with passwords.Check Version:
llama-stack --versionVerify Fix Applied:
After updating to 0.4.0rc3+, check that passwords are censored (e.g., shown as '******') in initialization logs.📡 Detection & Monitoring
Log Indicators:
- Plaintext database passwords in initialization logs
- Connection strings with visible credentials in log files
Network Indicators:
- None - this is a local information disclosure
SIEM Query:
source="llama-stack" AND "password" AND NOT "******"
