Exploitation Status

Palo Alto Networks is not aware of any malicious exploitation of this issue on any of our products.


No software updates are required at this time.

NOTE: Cortex XDR Broker VM versions earlier than Cortex XDR Broker VM 17.4.1 contain an affected version of the OpenSSL 3.0 library but are not impacted. There are no scenarios in Cortex XDR Broker VM software that enable successful exploitation of these vulnerabilities. The OpenSSL 3.0 library has been removed from Cortex XDR Broker VM 17.4.1 and later versions for security assurance.
