Details

ASA-2024-002: Default `PrepareProposalHandler` may produce invalid proposals when used with default `SenderNonceMempool` ## 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](https://github.com/cosmos/cosmos-sdk/security/advisories).
