{
  "original_root_cause": "SppagebuilderControllerAsset (site/controllers/asset.php) had no authentication, authorization, or CSRF check, so the uploadCustomIcon task could be reached by any unauthenticated remote caller and would extract an attacker-controlled ZIP into the web root.",
  "variant_root_cause": "Not applicable — no distinct variant or bypass was confirmed. The closest candidate, asset.loadCustomIcons, shares the same missing-auth root cause on the same controller class, but it reads from the database and does not perform file upload or extraction, so it is not a variant of the file-upload/RCE bug.",
  "equivalence_assessment": "The original CVE and the control endpoint (asset.uploadCustomIcon) share the exact same root cause and sink. The alternative task names and direct method invocations tested do not reach the sink. On the fixed 6.6.2 build, the new constructor guard blocks the same root cause for every task of the asset controller, so no equivalent unauthenticated path remains.",

  "notes": "The 6.6.2 patch is a surface-reduction + authorization fix. Because the guard is in the controller constructor, it closes the root cause for all methods of the class, not just uploadCustomIcon."
