CVE-2025-4674
Description
A flaw was found in cmd/go. The go command can execute arbitrary commands when processing untrusted version control system (VCS) repositories containing malicious configuration. This issue occurs because the command interprets VCS metadata, potentially leading to unintended command execution. This vulnerability allows a malicious actor to trigger this by providing a repository with a crafted VCS configuration, resulting in arbitrary code execution within the context of the go process.
Statement
This vulnerability is Important rather than Moderate because it enables arbitrary command execution at the tooling level before any code is built or reviewed, effectively compromising the software supply chain at its earliest stage. Unlike flaws that require user interaction with the code itself, this issue is triggered simply by running go operations on a malicious repository—an action routinely performed by developers and automated build systems. The problem lies in cmd/go’s unsafe interpretation of cross-VCS metadata, allowing an attacker to inject commands that execute with the privileges of the go process.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data
Many injection attacks involve the disclosure of important information -- in terms of both data sensitivity and usefulness in further exploitation.
Access Control
Technical Impact: Bypass Protection Mechanism
In some cases, injectable code controls authentication; this may lead to a remote vulnerability.
Other
Technical Impact: Alter Execution Logic
Injection attacks are characterized by the ability to significantly change the flow of a given process, and in some cases, to the execution of arbitrary code.
Integrity,Other
Technical Impact: Other
Data injection attacks lead to loss of data integrity in nearly all cases as the control-plane data injected is always incidental to data recall or writing.
Non-Repudiation
Technical Impact: Hide Activities
Often the actions performed by injected control code are unlogged.
