The [packet-forward-middleware](https://github.com/cosmos/ibc-apps/tree/main/middleware/packet-forward-middleware) module is an IBC middleware module built for Cosmos blockchains utilizing the IBC protocol allowing routing of incoming IBC packets from a source chain to a destination chain. The `packet-forward-middleware` module is vulnerable to potential chain-halt due to error non-determinism.\n\n### Patches\nPlease patch at your earliest convenience by applying one of the following patch versions, respective to the chain's ibc-go major version:\nv4.1.1\nv5.2.1\nv6.1.1","published":"2023-10-26T23:10:19Z","modified":"2024-08-21T14:57:07.751723Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/cosmos/ibc-apps/middleware/packet-forward-middleware/v4","fixedVersion":"4.1.1"},{"ecosystem":"Go","name":"github.com/cosmos/ibc-apps/middleware/packet-forward-middleware/v5","fixedVersion":"5.2.1"},{"ecosystem":"Go","name":"github.com/cosmos/ibc-apps/middleware/packet-forward-middleware/v6","fixedVersion":"6.1.1"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/cosmos/ibc-apps/security/advisories/GHSA-w6rp-vxj2-fjhr"},{"type":"PACKAGE","url":"https://github.com/cosmos/ibc-apps"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2024-08-21T14:57:07.751723Z"}}
