Vulnerability Title
Nautobot: REST API permits creation of GenericForeignKey references to objects that the user should not be able to reference
Source: CVE Program / CVE List V5
Vulnerability Description
Nautobot is a Network Source of Truth and Network Automation Platform. Prior to 2.4.33 and 3.1.2, in the case of inter-object references via GenericForeignKey (a pattern allowing an object to reference another object that may belong to one of several different "content types" or database tables), when creating or updating an object containing a GenericForeignKey, Nautobot's REST API failed to enforce user "view" permissions when determining whether a given reference to another object would be valid. This vulnerability is fixed in 2.4.33 and 3.1.2.
