CVE-2026-34048
CWE-285Published: July 7, 2026· Updated: Jul 7, 2026
Official Description
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 only check authentication and do not enforce terminal authorization, allowing a low-privileged team member to connect to terminal routes and execute commands on team servers. This issue is fixed in version 4.0.0-beta.471.
Risk Analysis
This critical vulnerability in Coolify allows low-privileged team members to execute commands on team servers due to insufficient authorization in terminal websocket bootstrap routes. With a CVSS score of 9.9, this flaw represents an extremely high risk, as it can lead to complete compromise of server integrity, confidentiality, and availability. The lack of an EPSS score means the exploitation likelihood is not yet quantified, but the severity is clear.
No public exploit is currently known for this vulnerability. However, it is remotely exploitable over the network with low attack complexity, requiring only low-privileged authentication.
Update Coolify to version 4.0.0-beta.471 or later to address the authorization bypass. Review and enforce strict role-based access controls within Coolify to ensure users only have access to necessary functionalities.
Technical Analysis
CVE-2026-34048 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), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.9.
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.
