undici: undici: Authentication bypass via cross-origin cache poisoning due to missing origin isolation

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 a...

Node.js Module Undici 7.17.x < 7.24.0 DoS

The nodejs module Undici detected on the host is version 7.17.x prior to 7.24.0. It is, therefore, affected by a denial of service vulnerability. When the deduplication interceptor is enabled, response data for deduplicated requests is accumulated in memory for downstream handlers. An...

Undici has Unbounded Memory Consumption in its DeduplicationHandler via Response Buffering that leads to DoS

Impact This is an uncontrolled resource consumption vulnerability CWE-400 that can lead to Denial of Service DoS. In vulnerable Undici versions, when interceptors.deduplicate is enabled, response data for deduplicated requests could be accumulated in memory for downstream handlers. An...
