Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Unhandled panics and incomplete state rollbacks during IBC packet processing or slash packet ingestion can trigger immediate, remote-triggered validator set/consensus halts on the provider chain. Proper context validation and error propagation are vital.
Auth Bypass: Bypasses in message filtering inside the AnteHandler decorators (including nested transactions within MsgExec) can allow unsupported module messages or unauthorized transactions before a CCV channel is fully established.
Denial of Service: Malicious or compromised consumer chains could flood the provider with mass-slashing packets, causing extreme processing bottlenecks or validator resource exhaustion unless strict rate limits and slash queues are enforced.
