Detailsinfo

A vulnerability, which was classified as very critical, was found in coollabsio Coolify up to 4.0.0-beta.470. This affects the function startUnmanaged/stopUnmanaged/restartUnmanaged of the component Livewire. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.471, the Livewire component Server\Resources exposes public methods (startUnmanaged, stopUnmanaged, restartUnmanaged) that accept a container ID parameter directly from the browser without any sanitization or escaping. This parameter is interpolated directly into shell commands executed via SSH on managed servers, enabling any authenticated team member to execute arbitrary OS commands on remote servers. This issue is fixed in version 4.0.0-beta.471.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-34058 since 03/25/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 07/07/2026). MITRE ATT&CK project uses the attack technique T1202 for this issue.

Upgrading to version 4.0.0-beta.471 eliminates this vulnerability.
