GHSA-33cr-m232-xqch
cheqd-node affected by Non-deterministic JSON Unmarshalling of IBC Acknowledgement
Description
An issue was discovered in IBC-Go's deserialization of acknowledgements that results in non-deterministic behavior which can halt a chain. Any user that can open an IBC channel can introduce this state to the chain.
This an upstream dependency used in cheqd-node, rather than a custom module.
Impact
Could result in a chain halt.
Patches
Validators, full nodes, and IBC relayers should upgrade to cheqd-node v3.1.7. This upgrade does not require a software upgrade proposal on-chain and is meant to be non state-breaking.
