@whatwg-node/fetch is vulnerable to Denial of Service (DoS)
75
High Risk
This Affects:
@whatwg-node/fetchTL;DR
Node's fetch transport in @whatwg-node/fetch follows HTTP redirects by recursively calling fetchNodeHttp again for every 3xx response with no limit on the number of hops. Request defaults redirect to follow, so a target that keeps returning redirects drives unbounded recursion and memory and resource growth on the Node HTTP path. The patch caps following at 20 redirects and rejects further hops with a TooManyRedirects error.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
