cheqd-node affected by Non-deterministic JSON Unmarshalling of IBC Acknowledgement

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. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
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
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-33cr-m232-xqch is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-33cr-m232-xqch. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-33cr-m232-xqch in your dependencies?
O3 detects GHSA-33cr-m232-xqch across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
