Enterprise Server 3.6 release notes

Packages have been updated to the latest security versions.

/var/log/lastlog was not copied over as a sparse file during ghe-upgrade, which could cause issues by using additional disk space.

As a security measure, GitHub Pages does not build sites that contain symbolic links except when using custom GitHub Actions workflows. When the page builder encounters a symbolic link, the build will fail with an error indicating that the symbolic link should be dereferenced. Custom workflows for GitHub Pages are available in GitHub Enterprise Server 3.7 and later.

Custom firewall rules are removed during the upgrade process.

Git LFS tracked files uploaded through the web interface are incorrectly added directly to the repository.

In a repository's settings, enabling the option to allow users with read access to create discussions does not enable this functionality.

Custom patterns for secret scanning have .* as an end delimiter, specifically in the "After secret" field. This delimiter causes inconsistencies in scans for secrets across repositories, and you may notice gaps in a repository's history where no scans completed. Incremental scans may also be impacted. To prevent issues with scans, modify the end of the pattern to remove the .* delimiter.

Following an upgrade to GitHub Enterprise Server 3.6 or later, existing inconsistencies in a repository such as broken refs or missing objects, may now be reported as errors like invalid sha1 pointer 0000000000000000000000000000000000000000, Zero-length loose reference file, or Zero-length loose object file. Previously, these indicators of repository corruption may have been silently ignored. GitHub Enterprise Server now uses an updated Git version with more diligent error reporting enabled. For more information, see this upstream commit in the Git project.

If you suspect a problem like this exists in one of your repositories, contact GitHub Enterprise Support for assistance.

On an instance in a high-availability configuration, passive replica nodes accept Git client requests and forward the requests to the primary node.

If an instance is configured to forward logs to a target server with TLS enabled, certificate authority (CA) bundles that a site administrator uploads using ghe-ssl-ca-certificate-install are not respected, and connections to the server fail.

When running ghe-config-apply, the process may stall with the message Deployment is running pending automatic promotion.

In rare circumstances, a small instance with both high availability and GitHub Actions configured may report that MSSQL replication is unhealthy after many upgrades with full upgrade packages. If you encounter this issue, contact GitHub Support.

To prevent commits from a detached repository from syncing to prior forks that are now in a separate repository network, GitHub Enterprise Server closes pull requests between repositories during detachment.

Packages have been updated to the latest security versions.

On an instance in a cluster configuration, the Cluster-Balance daemon would run against jobs not specified in the configuration.

On an instance with a GitHub Advanced Security license and secret scanning enabled, in some cases, custom patterns would erroneously show no results for a dry run.

When providing data to GitHub Support, GitHub Enterprise Server displays a notice describing how support data is used before uploading the support files.

Custom firewall rules are removed during the upgrade process.

Git LFS tracked files uploaded through the web interface are incorrectly added directly to the repository.

On an instance in a cluster configuration, when a site administrator sets maintenance mode on a single cluster node using ghe-maintenance -s, the utility warns the administrator to use ghe-cluster-maintenance -s to set maintenance mode on all of the clusters nodes. For more information, see "Enabling and scheduling maintenance mode."

When a site administrator configures an outbound web proxy server for GitHub Enterprise Server, the instance now validates top-level domains (TLDs) excluded from the proxy configuration. By default, you can exclude public TLDs that the IANA specifies. Site administrators can specify a list of unregistered TLDs to exclude using ghe-config. The . prefix is required for any public TLDs. For example, .example.com is valid, but example.com is invalid. For more information, see "Configuring an outbound web proxy server."

To avoid intermittent issues with the success of Git operations on an instance with multiple nodes, GitHub Enterprise Server checks the status of the MySQL container before attempting a SQL query. The timeout duration has also been reduced.

This vulnerability was reported via the GitHub Bug Bounty program and has been assigned CVE-2022-23741.

MEDIUM: An information disclosure vulnerability was identified in GitHub Enterprise Server that allowed private repositories to be added to a GitHub Actions runner group via the API by a user who did not have access to those repositories, resulting in the repository names being shown in the UI. To exploit this vulnerability, an attacker would need access to the GHES instance, permissions to modify GitHub Actions runner groups, and successfully guess the obfuscated ID of private repositories. This vulnerability was reported via the GitHub Bug Bounty Program and has been assigned CVE-2022-46257.

A race condition blocked upgrades to GitHub Enterprise Server 3.6 or later until a site administrator retried the upgrade.

Site administrators were not able to manage security products settings for repositories they had unlocked.

When a site administrator ran the ghe-repl-status command on a cache replica via the administrative shell (SSH), the command incorrectly reported overall Git and Alambic cluster replication status information as if it pertained only to cache replication.

When a site administrator ran the ghe-repl-sync-ca-certificates command from an instances primary node via the administrative shell (SSH), the command only replicated CA certificates from the instances primary node to a single replica node. The command did not replicate the certificates to all available replica nodes.

When using repository caching with an instance in a high availability configuration, if a Git client used SSH instead of HTTPS for a repositorys remote URL, Git LFS would fetch objects from the instances primary node instead of the appropriate cache replica node.

Installation of GitHub Enterprise Server on the VMware ESXi hypervisor failed due to the generation of an OVA file with an invalid capacity value.

When users performed an operation using the API, GitHub Enterprise Server enforced repository size quotas even when disabled globally.

The member webhook event did not include the from and to field values for the permission field as part of the changes field.

Adding a collaborator to a user-owned fork of a private, organization-owned repository with triage, maintain, or custom access resulted in a 500 error.

In some cases, the page for setting up code scanning would erroneously report that GitHub Actions was not configured for the instance.

After a user's account was deleted from the instance, image attachments that the user uploaded in comments were no longer visible in the web interface.

A debug-level message appeared in a system log, which could consume space rapidly on the instance's root storage volume.

To avoid failing domain verification due to the 63-character limit enforced by DNS providers for DNS records, the GitHub-generated TXT record to verify domain ownership is now limited to 63 characters.

After an enterprise owner enables Dependabot alerts, GitHub Enterprise Server enqueues the synchronization of advisory data to ensure hourly updates from GitHub.com.

GitHub Actions

• Within a workflow that calls a reusable workflow, users can pass the secrets to the reusable workflow with secrets: inherit. For more information, see "Reusing workflows."

• When using GitHub Actions, to reduce the risk of merging a change that was not reviewed by another person into a protected branch, enterprise owners and repository administrators can prevent Actions from creating pull requests. Organization owners could previously enable this restriction. For more information, see the following articles.

  • "Enforcing policies for GitHub Actions in your enterprise"
  • "Disabling or limiting GitHub Actions for your organization"
  • "Managing GitHub Actions settings for a repository"

• Users can write a single workflow triggered by workflow_dispatch and workflow_call, and use the inputs context to access input values. Previously, workflow_dispatch inputs were in the event payload, which increased difficulty for workflow authors who wanted to write one workflow that was both reusable and manually triggered. For workflows triggered by workflow_dispatch, inputs are still available in the github.event.inputs context to maintain compatibility. For more information, see "Contexts."

• To summarize the result of a job, users can generate Markdown and publish the contents as a job summary. For example, after running tests with GitHub Actions, a summary can provide an overview of passed, failed, or skipped tests, potentially reducing the need to review the full log output. For more information, see "Workflow commands for GitHub Actions."

• To more easily diagnose job execution failures during a workflow re-run, users can enable debug logging, which outputs information about a job's execution and environment. For more information, see "Re-running workflows and jobs" and "Using workflow run logs."

• If you manage self-hosted runners for GitHub Actions, you can ensure a consistent state on the runner itself before and after a workflow run by defining scripts to execute. By using scripts, you no longer need to require that users manually incorporate these steps into workflows. Pre- and post-job scripts are in beta and subject to change. For more information, see "Running scripts before or after a job."

GitHub Packages

• Enterprise owners can migrate container images from the GitHub Docker registry to the GitHub Container registry. The Container registry provides the following benefits.

  • Improves the sharing of containers within an organization
  • Allows the application of granular access permissions
  • Permits the anonymous sharing of public container images
  • Implements OCI standards for hosting Docker images

  The Container registry is in beta and subject to change. For more information, see "Migrating your enterprise to the Container registry from the Docker registry."

Community experience

• GitHub Discussions is available for GitHub Enterprise Server. GitHub Discussions provides a central gathering space to ask questions, share ideas, and build connections. For more information, see "GitHub Discussions."

• Enterprise owners can configure a policy to control whether people's usernames or full names are displayed within internal or public repositories. For more information, see "Enforcing repository management policies in your enterprise."

Organizations

• Users can create member-only READMEs for an organization. For more information, see "Customizing your organization's profile."

• Organization owners can pin a repository to an organization's profile directly from the repository via the new Pin repository dropdown. Pinned public repositories appear to all users of your instance, while public, private, and internal repositories are only visible to organization members.

Repositories

• While creating a fork, users can customize the fork's name. For more information, see "Fork a repo."

• Users can delete a branch that's associated with an open pull request. For more information, see "Creating and deleting branches within your repository."

• Repositories with multiple licenses display all of the licenses in the "About" sidebar on the Code tab. For more information, see "Licensing a repository."

• Users can require a successful deployment of a branch before anyone can merge the pull request associated with the branch. For more information, see "About protected branches" and "Managing a branch protection rule."

• Enterprise owners can prevent organization owners from inviting collaborators to repositories on the instance. For more information, see "Enforcing a policy for inviting collaborators to repositories."

• Users can grant exceptions to GitHub Apps for any branch protection rule that supports exceptions. For more information, see "About apps" and "Managing a branch protection rule."

Commits

• For public GPG signing keys that are expired or revoked, GitHub Enterprise Server verifies Git commit signatures and show commits as verified if the user made the commit while the key was still valid. Users can also upload expired or revoked GPG keys. For more information, see "About commit signature verification."

• To affirm that a commit complies with the rules and licensing governing a repository, organization owners and repository administrators can now require developers to sign off on commits made through the web interface. For more information, see "Managing the commit signoff policy for your organization" and "Managing the commit signoff policy for your repository."

Pull requests

• Using the file tree located in the Files changed tab of a pull request, users can navigate modified files, understand the size and scope of changes, and focus reviews. The file tree appears if a pull request modifies at least two files, and the browser window is sufficiently wide. For more information, see "Reviewing proposed changes in a pull request" and "Filtering files in a pull request."

• Users can default to using pull requests titles as the commit message for all squash merges. For more information, see "Configuring commit squashing for pull requests."

GitHub Mobile

• In GitHub Mobile for iOS 1.80.0 and later, users can edit files within a pull request's topic branch. Support for editing files will come to GitHub Mobile for Android in a future release. [Updated: 2022-09-13]

Releases

• When viewing the details for a particular release, users can see the creation date for each release asset. For more information, see "Viewing your repository's releases and tags."

• While creating a release with automatically generated release notes, users can see the tag identified as the previous release, then choose to select a different tag to specify as the previous release. For more information, see "Automatically generated release notes."

Markdown

• Editing Markdown in the web interface has been improved.

  • After a user selects text and pastes a URL, the selected text will become a Markdown link to the pasted URL.
  • When a user pastes spreadsheet cells or HTML tables, the resulting text will render as a table.
  • When a user copies text containing links, the pasted text will include the link as a Markdown link.

  For more information, see "Basic writing and formatting syntax."

• When editing a Markdown file in the web interface, clicking the Preview tab will automatically scroll to the place in the preview that you were editing. The scroll location is based on the position of your cursor before you clicked the Preview tab.

The unencrypted and unauthenticated Git protocol is now disabled by default. If you do not re-enable the protocol after you upgrade to GitHub Enterprise Server 3.6 or later, git:// connections on port 9418 will return the following error.

The unauthenticated git protocol on port 9418 is no longer supported.

If you wish to support the protocol in your environment, you must manually re-enable the feature. For more information, see "Enforcing repository management policies in your enterprise" and the GitHub Blog. [Updated: 2023-01-31]

Interactive elements in the web interface such as links and buttons show a visible outline when focused with a keyboard, to help users find the current position on a page. In addition, when focused, form fields have a higher contrast outline.

VMware vSphere ESXi hypervisor version 7.0 is now supported. [Updated: 2022-09-07]

Releases in the 3.6 series of GitHub Enterprise Server are no longer suitable for testing SCIM. To continue using the private beta of SCIM, upgrade your instance to version 3.7.3 or later. For more information, see "Upgrading GitHub Enterprise Server." [Updated: 2023-04-17]

On a freshly set up GitHub Enterprise Server instance without any users, an attacker could create the first admin user.

Custom firewall rules are removed during the upgrade process.

Git LFS tracked files uploaded through the web interface are incorrectly added directly to the repository.

When "Users can search GitHub.com" is enabled with GitHub Connect, issues in private and internal repositories are not included in GitHub.com search results.

Resource limits that are specific to processing pre-receive hooks may cause some pre-receive hooks to fail.

Actions services need to be restarted after restoring an instance from a backup taken on a different host.

In a repository's settings, enabling the option to allow users with read access to create discussions does not enable this functionality.

In some cases, users cannot convert existing issues to discussions.

Custom patterns for secret scanning have .* as an end delimiter, specifically in the "After secret" field. This delimiter causes inconsistencies in scans for secrets across repositories, and you may notice gaps in a repository's history where no scans completed. Incremental scans may also be impacted. To prevent issues with scans, modify the end of the pattern to remove the .* delimiter.

In some cases, GitHub Advanced Security customers who upgrade to GitHub Enterprise Server 3.6 may notice that alerts from secret scanning are missing in the web UI and REST API. To ensure the alerts remain visible, do not skip 3.4 as you upgrade to the latest release. To plan an upgrade through 3.4, see the Upgrade assistant.

• To display the missing alerts for all repositories owned by an organization, organization owners can navigate to the organization's Code security and analysis settings, then click Enable all for secret scanning. For more information, see "Managing security and analysis settings for your organization."
• To display the missing alerts for an individual repository, people with admin access to the repository can disable then enable secret scanning for the repository. For more information, see "Managing security and analysis settings for your repository."

A fix is available in the 3.6.1 patch release.

Instances experiencing a high sustained number of concurrent Git requests may experience performance issues. If you suspect that this issue is affecting your instance, contact GitHub Support. For more information, see "Creating a support ticket."

On instances in a high availability configuration, git push operations may fail in the following situations.

• During creation of the repository on a replica node
• After failure to create the repository on a replica node, before automatic repair of the repository [Updated: 2023-03-17]

An upgrade to GitHub Enterprise Server 3.6 or 3.7 from 3.5 or earlier may be long running if a large number of deleted repositories exist. Deleted repositories are purged automatically after 90 days, but for a faster upgrade they can be purged manually. If you suspect you have thousands of recently deleted repositories, and you are concerned about a long running upgrade, contact GitHub Enterprise Support for assistance purging deleted repositories.

On an instance configured for SAML authentication, when signing in, users may erroneously see an error indicating "User has already been taken." [Updated: 2023-07-18]

In rare circumstances, a small instance with both high availability and GitHub Actions configured may report that MSSQL replication is unhealthy after many upgrades with full upgrade packages. If you encounter this issue, contact GitHub Support. [Updated: 2023-08-24]

Changes to supported SSH algorithms

• In GitHub Enterprise Server 3.6 and later, GitHub is changing the supported algorithms and hash functions for Git operations over SSH. By default, SSH connections that satisfy both of the following conditions will fail.

  • The RSA key was added to a user account on your GitHub Enterprise Server instance after the cutoff date of midnight UTC on August 1, 2022.
  • The SSH client signs the connection attempt with the SHA-1 hash function.

  You can adjust the cutoff date. For more information, see "Configuring SSH connections to your instance." [Updated: 2023-01-31]

"Using secrets in GitHub Actions" incorrectly indicated that secrets for GitHub Actions are encrypted in the instance's database. The article has been updated to reflect that secrets are not encrypted on the instance. To encrypt secrets at rest, you must encrypt your instance's block storage device. For more information, refer to the documentation for your hypervisor or cloud service. [Updated: 2023-06-01]

The "Changes" section of these release notes indicated that if a user refreshes the page while creating a new issue or pull request, the assignees, reviewers, labels and projects will all be preserved. This change is not available in GitHub Enterprise Server 3.6, but is available in GitHub Enterprise Server 3.7 and later. [Updated: 2023-09-06]
