Hi Antoine,
I read your post twice but everything in it seems obvious. What am I
missing? It's obvious that (1) exogenous fee bumping requires keeping
an independent reserve of sufficient funds and (2) that the amount of
the reserve can vary depending on transaction size and prevalent
feerates. The earliest description of that problem I found is from more
than a year before your report (
https://github.com/lightningnetwork/lnd/pull/4908 ), but I suspect I
could find other even earlier discussion if I looked harder.
Is there more to this vulnerability report that I'm missing?
Thanks,
-Dave
