It involves an improper neutralization of special elements in output used by a downstream component, commonly referred to as an \u0026ldquo;injection\u0026rdquo; vulnerability. This flaw allows an unauthorized attacker to bypass a security feature over a network. The vulnerability was reported to Microsoft and assigned a CVSS v3.1 base score of 8.8, indicating a high severity.
