Detailsinfo

A vulnerability, which was classified as problematic, has been found in Nautobot up to 2.4.32/3.1.1. Affected by this issue is an unknown function of the component REST API. The manipulation of the argument current_head with an unknown input leads to a modification of assumed-immutable data vulnerability. Using CWE to declare the problem leads to CWE-471. The product does not properly protect an assumed-immutable element from being modified by an attacker. Impacted is integrity, and availability. CVE summarizes:

Nautobot is a Network Source of Truth and Network Automation Platform. Prior to 2.4.33 and 3.1.2, 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. This vulnerability is fixed in 2.4.33 and 3.1.2.

The advisory is available at github.com. This vulnerability is handled as CVE-2026-44798 since 05/07/2026. The exploitation is known to be easy. The attack may be launched remotely. Technical details are known, but there is no available exploit.

Upgrading to version 2.4.33 or 3.1.2 eliminates this vulnerability.
