What it is

URLModificationMiddleware resolves named-URL lookups

against unfiltered Model.objects before RBAC. The 403→404

shim only rewrites 403 responses, leaving the pk=0 miss

path with a different 404 detail string. Differential

"Not found." vs "No <Model> matches..." reveals whether

a named resource (org, credential, inventory, host) exists

anywhere on the platform. Enables cross-tenant internal

hostname enumeration.
