Summary

CVE-2023-34450: CometBFT versions 0.34.28 and 0.37.1 are affected by a vulnerability that can cause a deadlock when serializing struct `PeerState` to JSON. This issue can occur when the function MarshallJSON is called from two different places: through logs with the `consensus` logging module set to "debug" level and the log output format set to JSON, or via RPC `dump_consensus_state`. In case 1, the deadlock can impact most goroutines, effectively halting the node. In case 2, only the data structures related to the first peer and the thread(s) handling RPC requests will be deadlocked, blocking only one channel of communication with peers. The impacted peer will eventually be excluded from the list after a timeout. The vulnerability poses a medium severity risk according to NVD, with no privileges required for exploitation and low availability impact.
