This vulnerability is an incorrect authorization issue that allowed unauthorized users, specifically contractor accounts, to read the contents of internal repositories when the Contractors API feature was enabled. This feature is rarely enabled and was in private preview. The issue affected all versions of GitHub Enterprise Server prior to 3.18 and was fixed in versions 3.14.15, 3.15.10, 3.16.6, and 3.17.3.
How can this vulnerability impact me? :
The vulnerability could allow unauthorized contractor accounts to access sensitive internal repository data, potentially leading to exposure of confidential information or intellectual property. This unauthorized read access could compromise the security and confidentiality of internal projects and data.
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, ensure that the Contractors API feature is disabled if not needed, as it is a rarely-enabled feature. Additionally, upgrade GitHub Enterprise Server to one of the fixed versions: 3.14.15, 3.15.10, 3.16.6, or 3.17.3 or later.
