Official Description

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.471, LocalFileVolume::saveStorageOnServer builds shell commands using unescaped fs_path and parent_dir values before validation, and submitFileStorage does not validate the user-controlled file-mount path before creating a volume, allowing an authenticated user who can add file storage to execute commands when the storage is saved. This issue is fixed in version 4.0.0-beta.471.

Technical Analysis

CVE-2026-34153 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 8.8.
