CVE-2026-34047: Coollabsio Coolify

Critical severity, CVSS 9.9. 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, terminal WebSocket bootstrap routes did not enforce the expected authorization middleware, allowing an authenticated user to access terminal functionality for resources outside the authorized scope and potentially execute commands. 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)
