Fixed bug that allowed OAuth tokens improper access to SAML SSO protected organization resources when used with the `/issues` API endpoint

On September 15, 2022, we fixed a bug on GitHub.com that allowed OAuth tokens (such as personal access tokens) to bypass SAML single sign-on (SSO) requirements to view organization issue data using the /issues GitHub API endpoint.

The SAML SSO bypass could only happen when the token owner was a member of a SAML SSO protected organization, had the necessary permissions to view the issue data, and was using an OAuth token that was not authorized for use with SAML SSO. Integrations using an OAuth token matching the above criteria would also bypass SAML SSO requirements when making requests to the /issues API endpoint.

The accessible data included the title, body, labels, and assignee of the issue, but did not include comments on the issue itself. The bug did not allow organization members to view repository, issue, or other organization data that they did not have permission to view.

High-impact package maintainers now require 2FA

Starting today, two-factor authentication (2FA) will be enforced for maintainers of all high-impact npm packages. A package is marked as a high impact package when they have more than 1 million weekly downloads or have more than 500 dependents. Maintainers of such packages will be notified 15 days in advance to enroll for 2FA.

To learn more about configuring 2FA, see Configuring two-factor authentication.
To learn more about 2FA in general, see About two-factor authentication.
For questions and comments, open a discussion in our feedback repository.

Code scanning now supports using CodeQL packs on GitHub.com and GHES

CodeQL comes with a built-in package manager that helps you share and manage custom queries. Last year, we announced the public beta of CodeQL packaging — including direct integration into GitHub code scanning. This makes it easier to roll out custom queries to your repositories and gives you full control over exactly which queries are run.

This functionality will soon be released for users of GitHub Enterprise Server (GHES): it will be available with GHES 3.7. This release also includes support for using packs that are published to GitHub Container Registries (GHCR) hosted on GHES.

How do I use CodeQL query packs in code scanning?

To use CodeQL query packs in code scanning, specify a with: packs: entry in the uses: github/codeql-action/init@v2 section of your code scanning workflow. By default code scanning downloads packs the from GHCR on GitHub.com, so if you want to run one of the standard CodeQL query packs or any other public CodeQL query pack, then simply include the pack scope/name and version requirements here. You can find the full documentation here.

If you want to run packs from the GHCR on GHES, then you need to tell code scanning how to access and authenticate to the appropriate registry. For an example of how to do this in your code scanning workflow, see Downloading CodeQL packs from GitHub Enterprise Server in the GitHub documentation.

How do I publish my own CodeQL packs?

You can publish you own CodeQL packs using the CodeQL CLI. By default, the CodeQL CLI publishes packs to the GHCR on GitHub.com. If you want to publish packs to the GHCR associated with your instance of GHES, you need to tell the CodeQL CLI how to access and authenticate to the registry you want to work with. For a full example of how to specify these details, see Working with CodeQL packs on GitHub Enterprise Server in the CodeQL CLI documentation.

Where can I find more information about CodeQL packaging and code scanning?

This changelog post only provides a brief summary of how you can use CodeQL packs in code scanning. For more information, see:
