## GitHub Patches Critical RCE Vulnerability in git push Pipeline After Wiz Researchers Disclose Flaw
A critical remote code execution vulnerability in GitHub's core git push pipeline could have allowed any user with repository push access to execute arbitrary commands on GitHub's servers—requiring only a single crafted git push command. The vulnerability, reported by researchers at cloud security firm Wiz on March 4, 2026, affected github.com and the full suite of GitHub Enterprise products, including GitHub Enterprise Cloud, GitHub Enterprise Cloud with Data Residency, GitHub Enterprise Cloud with Enterprise Managed Users, and GitHub Enterprise Server. GitHub validated the finding and deployed a fix to github.com in under two hours, subsequently launching a forensic investigation that concluded no exploitation had occurred.

The attack vector exploited unsanitized input in git push options, enabling attackers with basic repository access—potentially including their own newly created repositories—to achieve arbitrary command execution on the server handling their push operation. The simplicity of the exploit—a single command with a crafted push option—underscored the severity of the flaw in a platform that serves as the backbone for millions of developers and enterprises worldwide. GitHub's security team responded through its Bug Bounty program, which facilitated rapid disclosure and coordinated remediation.

The incident highlights the persistent security challenges in developer infrastructure platforms where trusted operations like git push can become attack surfaces if input handling is not rigorously sanitized. While GitHub confirmed no evidence of exploitation, the vulnerability's scope—spanning the company's public cloud and enterprise offerings—signals the potential blast radius of flaws in foundational developer tools. GitHub has committed to sharing additional details on preventive measures in future communications, as the security community continues to scrutinize the integrity of software supply chain infrastructure.
