CVE-2026-34152 is a command injection vulnerability in Coolify, the open-source self-hostable platform for managing servers, applications, and databases. In versions prior to 4.0.0-beta.471, user-supplied pre-deployment and post-deployment commands are single-quote escaped, but are then transmitted to the target host via an SSH heredoc mechanism that preserves newline characters. Because newline preservation breaks the intended safety of the escaping approach, an authenticated user can inject additional shell statements into the deployment command stream. Those injected commands execute on the remote server in the context of the deployment process.
