undici is vulnerable to Denial of Service (DoS)
59
Medium Risk
This Affects:
undiciTL;DR
The retry handler leaves an already-exposed response body pending when a truncated successful response is retried and the retry returns a non-retryable status. The original body the application still holds is never ended or destroyed, so reads hang and bodyTimeout does not fire. A remote peer can repeat this to accumulate pending streams. The fix settles the original body when the handler replaces it.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you use the retry handler.

undici is vulnerable to Denial of Service (DoS) in versions 7.11.0 - 7.29.0 and 8.0.0 - 8.10.1.
