Description

Nautobot is a Network Source of Truth and Network Automation Platform built as a web application atop the Django Python framework with a PostgreSQL or MySQL database. When submitting a Job to run via a Job Button, only the model-level `extras.run_job` permission is checked (i.e., does the user have permission to run Jobs in general). Object-level permissions (i.e., does the user have permission to run this specific Job?) are not enforced by the URL/view used in this case. A user with permissions to run even a single Job can actually run all configured JobButton Jobs. Fix will be available in Nautobot 1.6.8 and 2.1.0

Affected products

nautobot: from 1.5.14 before 1.6.8; from 2.0.0 before 2.1.0 — fixed in 1.6.8, 2.1.0

How to fix

Upgrade to a fixed version: nautobot 1.6.8, 2.1.0. Check the vendor advisory for mitigations.
