ASA-2024-002: Default `PrepareProposalHandler` may produce invalid proposals when used with default `SenderNonceMempool`
Details

ASA-2024-002: Default PrepareProposalHandler may produce invalid proposals when used with default SenderNonceMempool

Component: Cosmos SDK Criticality: Medium Affected Versions: Cosmos SDK versions <= 0.50.3; <= 0.47.8 Affected Users: Chain developers, Validator and Node operators Impact: Denial of Service

Summary

When using the default PrepareProposalHandler and the default SenderNonceMempool, an issue was identified which may allow invalid blocks to be proposed when a single sender includes multiple transactions with non-sequential sequence numbers in certain conditions. If this state is reached, it can lead to a reduction in block production for a network.

Next Steps for Impacted Parties

If you are a chain developer on an affected version of the Cosmos SDK, it is advised to update to the latest available version of the Cosmos SDK for your project. Once a patched version is available, it is recommended that network operators upgrade.

A Github Security Advisory for this issue is available in the Cosmos-SDK repository. For more information about Cosmos SDK, see https://docs.cosmos.network/.
