Many thanks to all for the effort, including Junio.
Indeed. Thank you all for the efforts!
This addresses the security issues CVE-2026-111760, CVE-2026-113408,
CVE-2026-114466, CVE-2026-114467, CVE-2026-114469 and CVE-2026-105437.
* CVE-2026-113408:
It is possible for a server to advertise an unborn HEAD that contains
path-traversal characters (e.g., `refs/heads/../../../TARGET`). With
the files ref backend that can lead to ref-updating actions to write
to unwanted files.
See <https://gitlab.com/gitlab-org/git/-/work_items/809> for details.
FWIW, this and the other GitLab work item links appear to be
inaccessible to normal users. I'm guessing that's not the
intent.
I added Patrick to the Cc as one of the folks who may be
able to poke the right folks at GitLab to open them up?
Thank you for pointing it out. It was indeed not the intention. Those work items are accessible now.
