CVE-2021-41599

Name of the Vulnerable Software and Affected Versions GitHub Enterprise Server versions prior to 3.3

Description A remote code execution issue was identified in GitHub Enterprise Server that could be exploited when building a GitHub Pages site. To exploit this issue, an attacker would need permission to create and build a GitHub Pages site on the GitHub Enterprise Server instance. This issue was reported via the GitHub Bug Bounty program.

Recommendations For versions prior to 3.0.21, update to version 3.0.21. For versions prior to 3.1.13, update to version 3.1.13. For versions prior to 3.2.5, update to version 3.2.5. As a temporary workaround, consider restricting permissions to create and build GitHub Pages sites on the GitHub Enterprise Server instance until a patch is applied.
