Vulnerability from github – Published: 2025-03-11 21:54 – Updated: 2025-03-14 20:05

Summary

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

Details

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.

References

Severity

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
