Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.55%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Improper input handling in the 'Host Header' allows an unauthenticated attacker to store a payload in web application logs. When an Administrator views the logs using the application's standard functionality, it enables the execution of the payload, resulting in Stored XSS or 'Cross-Site Scripting'.
