CVE-2026-34149 coollabsio CVE debrief

CVE-2026-34149 is a command injection vulnerability in Coolify's DatabaseBackupJob feature. Prior to version 4.0.0-beta.471, user-controlled database credentials and MongoDB collection exclusion names are interpolated into backup shell commands without adequate escaping. This allows an authenticated user with database management permissions to execute commands on managed servers. The vulnerability has a low CVSS score of 3.3, but it can still have significant impacts if exploited. Users of Coolify, especially those with database management permissions, should be aware of this vulnerability and take steps to protect themselves.

Recommended defensive actions

  • Upgrade to Coolify version 4.0.0-beta.471 or later
  • Restrict database management permissions to only those who need them
  • Monitor for suspicious activity on managed servers
  • Implement additional security controls, such as input validation and sanitization
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
