By injecting a cookie with certain special characters, an attacker on a
shared subdomain which is not a secure context could set and thus overwrite
cookies from a secure context, leading to session fixation and other
attacks. This vulnerability affects Firefox ESR < 102.3, Thunderbird <
102.3, and Firefox < 105.
