bandit is vulnerable to Denial of Service (DoS)

High Risk
This Affects:
banditTL;DR
In bandit, hTTP/2 connection-window starvation pins Plug processes indefinitely in Bandit. The equivalent block on the stream-level send window is already bounded at 15 seconds; the connection-level path had no such bound. Each stalled stream pins its process, Plug state, and any resource the Plug holds across the blocked write, such as a pooled upstream connection in a reverse-proxy Plug.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
Background info
