Description
Coolify versions prior to v4.0.0-beta.420.7 are vulnerable to a remote code execution vulnerability in the project deployment workflow. The platform allows authenticated users, with low-level member privileges, to inject arbitrary shell commands via the Git Repository field during project creation. By submitting a crafted repository string containing command injection syntax, an attacker can execute arbitrary commands on the underlying host system, resulting in full server compromise.

Comprehensive Technical Analysis of EUVD-2025-25912
1. Vulnerability Assessment and Severity Evaluation
The vulnerability described in EUVD-2025-25912 affects Coolify versions prior to v4.0.0-beta.420.7. It is a remote code execution (RCE) vulnerability in the project deployment workflow, allowing authenticated users with low-level member privileges to inject arbitrary shell commands via the Git Repository field during project creation.
Severity Evaluation:
- Base Score: 9.4 (Critical)
- Base Score Version: CVSS 4.0
- Base Score Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H
The high base score indicates that this vulnerability is critical. The attack vector is network-based (AV:N), requires low complexity (AC:L), and does not need user interaction (UI:N). The attacker requires low privileges (PR:L), and the impact on confidentiality, integrity, and availability is high (VC:H, VI:H, VA:H). The scope change is also high (SC:H), affecting the security impact (SI:H) and availability impact (SA:H).
2. Potential Attack Vectors and Exploitation Methods
Attack Vectors:
- Authenticated Users: The vulnerability can be exploited by authenticated users with low-level member privileges.
- Git Repository Field: The injection point is the Git Repository field during project creation.
Exploitation Methods:
- Command Injection: An attacker can submit a crafted repository string containing command injection syntax to execute arbitrary commands on the underlying host system.
- Shell Commands: The injected commands can be used to gain full control over the server, leading to a complete compromise.
3. Affected Systems and Software Versions
Affected Systems:
- Coolify versions prior to v4.0.0-beta.420.7
Software Versions:
