Recurring patterns

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

Sandbox Escape: Integrating complex external virtual machine layers like the 08-wasm light client creates significant sandbox-escape risks. The vulnerability required completely removing the 08-wasm module and its snapshotter instance from the application configuration to eliminate runtime hazards.
Data Integrity: Using incorrect database storage key prefixes in blockchain state operations can corrupt parameters, block state migrations, and halt consensus engines. Ensuring key-value determinism is critical.
Auth Bypass: Decorators and ante-handlers that fail to inspect nested wrappers (such as authz messages) can allow users to bypass critical validation rules like commission change rate limits.
