Description
URLModificationMiddleware resolves named-URL lookups<br />
against unfiltered Model.objects before RBAC. The 403→404<br />
shim only rewrites 403 responses, leaving the pk=0 miss<br />
path with a different 404 detail string. Differential<br />
"Not found." vs "No matches..." reveals whether<br />
a named resource (org, credential, inventory, host) exists<br />
anywhere on the platform. Enables cross-tenant internal<br />
hostname enumeration.
Impact
