CVE-2026-3307 is a low-severity vulnerability affecting github enterprise_server. It was published on April 21, 2026 and has a CVSS 3.1 base score of 2.7 (LOW).
This vulnerability has a CVSS 3.1 base score of 2.7, rated LOW. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
An authorization bypass vulnerability was identified in GitHub Enterprise Server that allowed an attacker with admin access on one repository to modify the secret scanning push protection delegated bypass reviewer list on another repository by manipulating the owner_id parameter in the request body. Authorization was verified against the repository in the URL, but the action was applied to a different repository specified in the request body. The impact is limited to assigning existing trusted users as bypass reviewers; it does not allow adding arbitrary external users. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.21 and was fixed in versions 3.14.25, 3.15.20, 3.16.16, 3.17.13, 3.18.7, 3.19.4 and 3.20.1. This vulnerability was reported via the GitHub Bug Bounty program.
Remediation
Check the references section for vendor advisories and patches from github. Update enterprise_server to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
