Bootstrap 4.3 reaching EOS

JuanMAbellan — Wed, 03 Sep 2025 14:55:16 GMT

Hello community,

we have been informed that Bootstrap 4 is reaching EOS and this could cause a vulnerability, and I would like to know if there is any information about which firmware version uses this ?

Is it a real potential threat?

Thanks in advance!

@JuanMAbellan,

You can check what version of bootstrap your firewall is using by going directly to the resource (IE: https://<FQDN>/global-protect/portal/css/bootstrap.min.css) and looking at the version number. Say for example you're running PAN-OS 10.2 still and see 4.3.1, the thing to be mindful of is that it doesn't actually have any vulnerabilities present. So while PAN absolutely should have updated it at some point, it isn't causing any active issues.
