Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Auth Bypass: Inadequate identity validation allowed callers to modify state on behalf of other accounts. This was fixed by ensuring the message signer strictly matches the owner of the target entity retrieved during message execution. Developers must verify that all state-modifying endpoints in msg_server.go enforce identity checks against the underlying resource owner.

Auth Bypass: Inconsistent or missing struct tags in transaction types caused non-deterministic Amino/JSON serialization, resulting in inconsistent message signatures. This could bypass message verification or cause valid transactions to be rejected by the state machine. Future structural changes to transaction or state payloads must enforce strict, deterministic JSON serialization tags.

Denial of Service: Unbounded or unmetered loops processing message arrays or allowlists allowed resource-intensive operations without proportional gas consumption. This could be exploited to exhaust validator resources and stall the blockchain network. Any collection processing or iterative validation logic must explicitly consume gas proportional to the workload size.
