Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.94%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Coolify versions prior to v4.0.0-beta.420.6 are vulnerable to a remote code execution vulnerability in the application deployment workflow. The platform allows authenticated users, with low-level member privileges, to inject arbitrary Docker Compose directives during project creation. By crafting a malicious service definition that mounts the host root filesystem, an attacker can gain full root access to the underlying server.
