Impact assessment and necessary measures announced

Response information checked

Current re-audit: Source inaccessible; on hold · Research date: 2026-10-28

The October 21 public notice describes initial assessment and prioritizing mitigation and fixes where exposed. An October 23 update links a customer FAQ; the public notice alone does not establish product-specific completion.

Scope: This is the public-notice scope, not a blanket patched/unaffected assessment for every group brand or separately operated product.

Some official sources could not be retrieved. Reverification remains on hold and the previous verification date is retained.

What users should do

Use your product FAQ or support contact to confirm current impact, completion and required customer actions.
