CVE-2026-34171: Coollabsio Coolify

High severity, CVSS 8.0. EPSS: 0.2% 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, the GET /invitations/{uuid} endpoint can perform a state-changing password reset using an attacker-known invitation UUID, allowing an attacker who can cause a victim to visit the crafted invitation URL to reset the victim account password to a predictable value. 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)
