MEDIUM 5.1EPSS 0.32%

Does this matter?

Lower severity and a low EPSS score (0.32%). Track it; it rarely justifies an emergency change on its own.

Description

Open redirection vulnerability due to insufficient validation of the X-Forwarded-Host HTTP header. An attacker could create manipulated links that, when opened by a victim, cause the victim to be redirected to domains controlled by the attacker, enabling phishing or deception attacks with limited impact on confidentiality and integrity.
