CVE-2026-34049

Coolify: Command Injection via unsanitized MongoDB collection names in database backup

3.3 Low

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. From 4.0.0-beta.451 through 4.0.0-beta.470, database backup handling for MongoDB collection names did not fully validate shell metacharacters, allowing a highly privileged attacker who can configure backup inputs to inject commands. This issue is fixed in version 4.0.0-beta.471.
