Does this matter?
Lower severity and a low EPSS score (2.58%). Track it; it rarely justifies an emergency change on its own.
Description
When using Apache Knox SSO prior to 1.6.1, a request could be crafted to redirect a user to a malicious page due to improper URL parsing. A request that included a specially crafted request parameter could be used to redirect the user to a page controlled by an attacker. This URL would need to be presented to the user outside the normal request flow through a XSS or phishing campaign.
