CVE-2026-34152: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in coollabsio coolify
Coolify versions prior to 4.0.0-beta.471 contain an OS command injection vulnerability in the handling of pre-deployment and post-deployment commands. These commands are single-quote escaped but then transmitted via SSH heredoc, which preserves newlines and allows an authenticated user to inject additional shell commands on the remote server during deployment. This vulnerability is fixed starting from version 4.0.0-beta.471.
AI Analysis
Technical Summary
CVE-2026-34152 is an OS command injection vulnerability in Coolify, an open-source server and application management tool. The issue arises because pre-deployment and post-deployment commands, although single-quote escaped, are sent through SSH heredoc transport that preserves newlines. This allows an authenticated user to inject arbitrary shell commands that execute on the remote server during deployment. The vulnerability affects versions before 4.0.0-beta.471 and is addressed in that version.
Potential Impact
An authenticated user can execute arbitrary shell commands on the remote server during deployment, potentially leading to full compromise of the server, including confidentiality, integrity, and availability impacts. The CVSS 3.1 score is 8.8 (High), reflecting network attack vector, low attack complexity, required privileges, no user interaction, and high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Upgrade to Coolify version 4.0.0-beta.471 or later, where this vulnerability is fixed. No other official remediation or temporary fixes are documented. Ensure only trusted users have deployment privileges to reduce risk until the upgrade is applied.
