Versions prior to 0.28.0 contain a potential attack via Improper Verification of Cryptographic Signature, affecting anyone using the tendermint-light-client and related packages to perform light client verification (e.g. IBC-rs, Hermes). The light client does not check that the chain IDs of the trusted and untrusted headers match, resulting in a possible attack vector where someone who finds a header from an untrusted chain that satisfies all other verification conditions (e.g. enough overlapping validator signatures) could fool a light client. The attack vector is currently theoretical, and no proof-of-concept exists yet to exploit it on live networks. This issue is patched in version 0.28.0. There are no workarounds.\n\ud83d\udccf Published: 2022-12-15T00:01:04.540Z\n\ud83d\udccf Modified: 2025-04-18T15:59:54.978Z\n\ud83d\udd17 References:\n1. https://github.com/informalsystems/tendermint-rs/security/advisories/GHSA-xqqc-c5gw-c5r5", "creation_timestamp": "2025-04-18T16:59:06.000000Z"} 2025-04-18T16:59:06+00:00
