Does this matter?

Lower severity and a low EPSS score (0.74%). Track it; it rarely justifies an emergency change on its own.

Description

Set-Cookie response headers were being incorrectly honored in multipart HTTP responses. If an attacker could control the Content-Type response header, as well as control part of the response body, they could inject Set-Cookie response headers that would have been honored by the browser.
