Recently, the Cosmos-SDK team became aware of a high-severity security vulnerability that impacts Cosmos-SDK v0.43.x and v0.44.x and can result in a consensus halt. User funds are NOT at risk; however, the vulnerability can result in a chain halt. This vulnerability does not impact the current Cosmos Hub, though other Cosmos-SDK based blockchains using v0.43.x or v0.44.x may be affected and are advised to update to v0.44.2 immediately.
