We want to give you advance notice of an upcoming security change that may affect GitHub Enterprise Server (GHES) support bundle uploads.

Beginning August 18, 2026, GitHub will start rejecting command-line support bundle uploads from older GHES appliances that have not been updated with the required security patches.

To avoid any disruption when submitting support bundles with ghe-support-bundle, ghe-cluster-support-bundle, or ghe-support-upload commands, please update your GHES instance to the latest patch release available for your current version line. At minimum, the required patch versions are:

If your instance is running a GHES version that is no longer supported, we strongly recommend upgrading to a supported version as soon as possible.

If you’re unable to update to the required patch version before August 18, 2026, and need to upload a support bundle, please contact GitHub Support so we can help you with next steps.
