Summary
### Impact Chains using affected versions of Packet Forward Middleware in their IBC Transfer stack are vulnerable to an attack in which there is a potential denial of service. This affects IBC transfers for any asset which is being transferred between another chain and its native chain. We recommend upgrading as soon as possible. __THIS IS A STATE BREAKING CHANGE__ ### Patches Versions [7.2.1](https://github.com/cosmos/ibc-apps/releases/tag/middleware%2Fpacket-forward-middleware%2Fv7.2.1) and [8.1.1](https://github.com/cosmos/ibc-apps/releases/tag/middleware%2Fpacket-forward-middleware%2Fv8.1.1) are patched. ### Workarounds N/A ### References N/A
