CVE-2026-34152: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in coollabsio coolify
Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.471, pre-deployment and post-deployment commands are single-quote escaped but then sent through SSH heredoc transport that preserves newlines, allowing an authenticated user to inject additional shell statements that execute on the remote server during deployment. This issue is fixed in version 4.0.0-beta.471.
AI Analysis
Technical Summary
CVE-2026-34152 is an OS command injection vulnerability in coollabsio's Coolify tool before version 4.0.0-beta.471. The issue arises because pre-deployment and post-deployment commands, although single-quote escaped, are sent through SSH heredoc transport that preserves newlines. This behavior enables an authenticated user to inject arbitrary shell commands that execute on the remote server during deployment. The vulnerability is addressed in version 4.0.0-beta.471.
Potential Impact
Successful exploitation allows an authenticated user to execute arbitrary shell commands on the remote server during deployment, potentially leading to full compromise of the server, including confidentiality, integrity, and availability impacts.
Mitigation Recommendations
Upgrade to Coolify version 4.0.0-beta.471 or later, where this vulnerability is fixed. Patch status is confirmed by the version information stating the fix is in 4.0.0-beta.471. No other mitigation guidance is provided.
