Does this matter?

Lower severity and a low EPSS score (0.72%). Track it; it rarely justifies an emergency change on its own.

Description

It was discovered that on Windows operating systems specifically, Kibana was not validating a user supplied path, which would load .pbf files. Because of this, a malicious user could arbitrarily traverse the Kibana host to load internal files ending in the .pbf extension. Thanks to Dominic Couture for finding this vulnerability.
