Summary
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.
Red Hat severity: Important — CVSS 7.4 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N). Weakness: CWE-346.
