Actively exploited in the wild — prioritise confirming exposure.

Why High

High rather than Critical: exposure is scored at a default because we cannot see your systems or suppliers. If you run or depend on Palo Alto Networks PAN-OS, treat it as Critical.

Briefing

  • Do not treat uncorroborated claims as confirmed breaches.

Questions to ask IT

  • Do we run Palo Alto Networks PAN-OS, and which versions?
  • Is any of it reachable from the internet?
  • Have we checked whether it has already been used against us?
  • If it is still not patched, what mitigation is in place, and what is holding the fix up?

Next steps

  1. Confirm exposure and remediation status for affected products
