Vulnerability from cvelistv5 – Published: 2023-03-02 20:54 – Updated: 2025-03-05 20:05

Title

Code injection in GitHub Enterprise Server leading to arbitrary environment variables in GitHub Actions

Summary

A code injection vulnerability was identified in GitHub Enterprise Server that allowed setting arbitrary environment variables from a single environment variable value in GitHub Actions when using a Windows based runner. To exploit this vulnerability, an attacker would need existing permission to control the value of environment variables for use with GitHub Actions. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.8.0 and was fixed in versions 3.4.15, 3.5.12, 3.6.8, 3.7.5. This vulnerability was reported via the GitHub Bug Bounty program.
