CVE-2026-34152: Coollabsio Coolify

High severity, CVSS 8.8. EPSS: 0.7% chance of exploitation in the next 30 days.

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.

Affected products

• Coollabsio Coolify: before 4.0.0-beta.471 (fixed in 4.0.0-beta.471)
