Potential inter-blockchain communication (IBC) protocol compromise via "Dragonberry" vulnerability in cheqd


This vulnerability affects IBC transfers due to a security vulnerability dubbed "Dragonberry" upstream in Cosmos SDK. The vulnerability could allow malicious attackers to compromise chain-to-chain IBC transfers.

There is no vulnerability in the DID/resource modules for cheqd-node.


Node operators are requested to upgrade to cheqd-node v0.6.9 as soon as possible. Installation instructions are in the release notes. Please do not install any beta/pre-release versions.


No. The patch takes effect when more than 2/3rds of the voting power of the cheqd network has upgraded to this patch.

An emergency hotfix was released previously under v0.6.8 but this is now deprecated since Cosmos SDK v0.45.9 officially fixes this upstream.
