summary: Denial of service via OOM in github.com/cometbft/cometbft
description: |-
A bug in the CometBFT middleware causes the mempool's two data structures to
fall out of sync. This can lead to duplicate transactions that cannot be
removed, even after they are committed in a block. The only way to remove the
transaction is to restart the node. This can be exploited by an attacker to
bring down a node by repeatedly submitting duplicate transactions.
