CVE-2026-34034: 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.466, the sentinel_token setting is used in shell commands without sufficient validation, allowing an authenticated user with access to server Sentinel settings to inject shell syntax and execute commands on the host when Sentinel is restarted. This issue is fixed in version 4.0.0-beta.466.
AI Analysis
Technical Summary
CVE-2026-34034 describes an OS command injection vulnerability (CWE-78) in coollabsio's Coolify product. Specifically, the sentinel_token configuration is incorporated into shell commands without sufficient sanitization, enabling an authenticated user with access to Sentinel settings to inject shell syntax and execute arbitrary commands on the underlying host system during Sentinel restart operations. This vulnerability affects versions prior to 4.0.0-beta.466 and is resolved in that version.
Potential Impact
Successful exploitation allows an authenticated user with access to Sentinel settings to execute arbitrary operating system commands with the privileges of the Coolify process. This can lead to full compromise of the host system, including confidentiality, integrity, and availability impacts as indicated by the CVSS score of 8.8 (high severity).
Mitigation Recommendations
Upgrade to version 4.0.0-beta.466 or later, where this vulnerability is fixed. No other official remediation or temporary fixes are documented. Until upgrading, restrict access to Sentinel settings to trusted users only.
