CWE-639Published: July 7, 2026· Updated: Jul 9, 2026
Official Description
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.
Technical Analysis
CVE-2026-34044 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), with a CVSS base score of 7.7.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
