MEDIUM 5.1EPSS 0.31%

Does this matter?

Lower severity and a low EPSS score (0.31%). Track it; it rarely justifies an emergency change on its own.

Description

Improper handling of HTTP headers that allows a remote attacker to manipulate the value of the Host header using specially crafted requests. A successful exploit could result in the generation of manipulated links or responses, potentially leading to limited information disclosure or compromising the integrity of dependent services.
