CometBFT is a Byzantine Fault Tolerant BFT middleware that takes a state transition machine and replicates it on many machines. The mempool maintains two data structures to keep track of outstanding transactions: a list and a map. These two data structures are supposed to be in sync all the time ...

CVE-2023-34450

CometBFT (CVE-2023-34450) describes a deadlock in PeerState JSON serialization introduced by a change in versions 0.34.28 and 0.37.1. The deadlock can be triggered either by logging to JSON (consensus module set to debug) or by the RPC dump_consensus_state, potentially halting the node. The issue...
