Vulnerability in nautobot (CVE-2026-44798)
Summary
Vulnerability in nautobot (CVE-2026-44798). Risk of unauthorized operations or information disclosure. Exploitable via current_head. Mitigation: upgrade to 2.4.33 or later.
Original description
The description as published by the source.
Impact
A user with access to add/change a GitRepository record could use the REST API to directly set the current_head field on the record, which was not intended to be user-editable. Doing so could cause Nautobot's local clone(s) of the relevant repository to checkout a commit other than the latest commit on the specified branch (resulting in misleading state), or potentially to be unable to make use of the repository at all (until manually remediated) due to the current_head pointing to a nonexistent commit hash or malformed value.
Patches
The issue has been remediated in Nautobot v2.4.33 and 3.1.2.
Workarounds
Note that many of the same end-result symptoms could be caused by a user with the same level of access simply changing the branch or remote_url of a GitRepository rather than crafting the current_head. Administrators are encouraged to carefully review which users are granted permissions to create and modify GitRepository records.
