CyberRota Analysis
AI-GeneratedAn authorization bypass vulnerability in GitHub Enterprise Server allows authenticated users to access raw diffs or patches of pull requests in private repositories without proper authorization. This occurs because access tokens are scoped to repository names and pull request numbers, enabling attackers to exploit this by creating repositories with matching names and numbers. Organizations using affected versions prior to 3.22 should prioritize patching to mitigate potential data exposure risks.

Original NVD Description
An authorization bypass vulnerability was identified in GitHub Enterprise Server that allowed any authenticated user of the instance to read the raw diff or patch of pull requests in private repositories without authorization. Access tokens for raw pull request diffs and patches were scoped to the repository name and pull request number rather than to a globally unique repository identifier, so an attacker who created a repository and pull request matching a target's repository name and pull request number could use a token for their own repository to retrieve the private pull request's contents. Exploitation required the attacker to know the target repository's name and a valid pull request number. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.22 and was fixed in versions 3.17.21, 3.18.15, 3.19.12, 3.20.8, and 3.21.6. This vulnerability was reported via the GitHub Bug Bounty program.
