Overview
org.webjars.npm:undici is an An HTTP/1.1 client, written from scratch for Node.js
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the interceptors.decompress() interceptor, which caps the decompression chain at 5 layers but does not bound the total decompressed output size. An attacker can exhaust memory and crash the process by delivering, from a malicious upstream, a small compressed response whose Content-Encoding expands to gigabytes. This requires the application to use the interceptors.decompress() interceptor against untrusted or compromised upstream servers.
