There have been two upstream security advisories and associated patches published under ISA-2025-001 and ISA-2025-002.
ISA-2025-001 affects the IBC-Go package., where non-deterministic JSON unmarshalling of IBC Acknowledgements can result in a chain halt.
ISA-2025-002 affects the Cosmos SDK package, where x/group can halt when erroring in EndBlocker.
If unaddressed, this could result in a chain halt.
Validators, full nodes, and IBC relayers should upgrade to cheqd-node v3.1.8. This upgrade does not require a software upgrade proposal on-chain and is meant to be non state-breaking.
