Description OSIDB Bzimport 2026-08-06 22:50:19 UTC 
A flaw was found in automation-controller. The named-URL resolution middleware resolves resource lookups against the unfiltered queryset before RBAC enforcement,
  ▎ and the 403-to-404 shim does not normalize the response body for the pk=0 miss path. An attacker can distinguish "Not found." (resource exists but access 
  ▎ denied) from "No <Model> matches the given query." (resource does not exist), enabling cross-tenant enumeration of organization names, credential names, 
  ▎ inventory names, and hostnames.
