CVE-2026-34044: Coollabsio Coolify

High severity, CVSS 7.7. EPSS: 0.4% 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.466, the Logs::mount() component looks up resources by UUID without scoping the lookup to the current team, allowing an authenticated user to access logs for applications owned by other teams by supplying a victim resource UUID. This issue is fixed in version 4.0.0-beta.466.

Affected products

• Coollabsio Coolify: before 4.0.0-beta.466 (fixed in 4.0.0-beta.466)
