undici: undici: Cross-user cookie disclosure via Set-Cookie caching

A flaw was found in undici. The software's caching mechanism, when operating in shared cache mode, improperly stores responses that include 'Set-Cookie' headers. This oversight allows an untrusted server to inject cookies into cached responses. Consequently, sensitive cookie information from one...
