   “HPE bulletin HPESBNW05162 (Oct 22) is JS-only, so versions come from cve.org record and press reading it; fixed versions via cybersecuritynews, not read on HPE page directly. HPE: no known PoC or exploitation. Did not search social posts.”

   “PAPI is core controller/AP and conductor/managed-device control traffic on UDP 8211 (predefined svc-papi in AOS-8 docs), so treat it as on by default; I found no off switch. Triage's not-affected-if default-config looks wrong: do not skip on that basis. papi-security enhanced-security defaults to Disable, but HPE has not said it mitigates this CVE. HPE bulletin still unread directly.”
