Official Description

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.464, the cloneTo() Livewire action in ResourceOperations.php authorizes the source resource but resolves destination resources with unscoped Eloquent lookups, allowing an authenticated user to clone resources into destinations owned by other teams and access cross-tenant resources. This issue is fixed in version 4.0.0-beta.464.

NVD Source

Risk Analysis

This critical vulnerability in Coolify allows an authenticated user to clone resources into destinations owned by other teams, leading to cross-tenant resource access. With a CVSS score of 9.9, this flaw represents an extremely high risk, as it can compromise the confidentiality of data across different teams. 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 authenticated access.

Recommended Action

Update Coolify to version 4.0.0-beta.464 or later to address the improper authorization in the cloneTo() action. Ensure that all resource operations strictly enforce tenant and team boundaries.

Technical Analysis

CVE-2026-34037 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), 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.
