Code scanning shows more accurate and relevant alerts on pull requests

Code scanning is now using a new way of analysing and displaying alerts on pull requests. The change ensures code scanning only shows accurate and relevant alerts for the pull request.

Previously, code scanning presented all alerts unique to the pull request branch, even if they were unrelated to the code changes the pull request introduced. Now, the tool reports only alerts inside the lines of code that the pull request has changed, which makes it easier to fix these contextualised alerts in a timely manner.

The complete list of code scanning alerts on the pull request branch can be seen on the Security tab of the repository.

In addition, code scanning will no longer show fixed alerts on pull requests. Instead, you can check whether an alert has been fixed by your pull request on the Security tab of the repository by using search filters: pr:111 tool:CodeQL. If you fix an alert in the initial commit in the pull request, it will not be present on the PR branch.

This has shipped to GitHub.com and will be available in GitHub Enterprise Server 3.10.

SSH Certificate requirement update

The "Require SSH certificates" policy now allows GitHub apps to call Git APIs using a user-to-server token, bringing them up to parity with OAuth app support.

The SSH certificate requirement mandates that users in your organization call Git APIs using an SSH certificate issued by your organization, in place of their own SSH key or a PAT.
To support automation, it has an exception in place for OAuth apps and GitHub app server-to-server tokens, which allows applications you've approved to call Git APIs for your organization.
With this change, we are extending that exception to GitHub app user-to-server tokens, for when a user has signed into a GitHub app that's installed in your organization.

This change also applies when the enterprise-level setting requires SSH certificates across all organizations in the enterprise.

Fixed bug that allowed removed users to retain access to the organization

GitHub Security was notified about an issue where users still had access to organizations after being removed. Our Security team investigated potential instances and determined there were occasional instances where users’ permissions were not fully removed when teams were deleted or they were part of a team when they were removed from the organization. While we investigated the root causes, which stemmed from background job and permissions issues, a manual fix has been implemented since October 20, 2022. We have addressed the underlying issues and the need for the previously implemented manual fix. We have also cleaned up any users that were not removed when they should have been. There is no further action that is required by any organization.
