Description

A flaw was found in undici. When the cache or deduplicate interceptor is directly composed onto a Client or Pool, the destination origin is omitted from cache and request-deduplication keys. This allows a remote attacker to perform cross-origin cache poisoning, leading to information disclosure and potentially a full authentication bypass. An attacker could exploit this by having a trusted origin accept a malicious token, without contacting the legitimate trusted origin.
