cheqd-node affected by Non-deterministic JSON Unmarshalling of IBC AcknowledgementGHSA-33cr-m232-xqch
Fix: cosmos/ibc-go@59987d5GHSA-33cr-m232-xqch is a remote code execution vulnerability in github.com/cheqd/cheqd-node. A fix is available for github.com/cheqd/cheqd-node — see the affected versions and patch details below.
Real-World Exposure
github.com/cheqd/cheqd-nodeReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/cheqd/cheqd-node, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/cheqd/cheqd-node to 3.1.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-33cr-m232-xqch is resolved across your whole dependency graph.
Workarounds
Do not deserialise data from untrusted sources: where the format allows it, restrict deserialisation to an explicit allowlist of expected types, and prefer a data-only format (JSON, Protobuf) over one that can reconstruct arbitrary objects until you can upgrade.
