Recurring patterns

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

Auth Bypass: User-submitted contract configurations could bypass chain-wide permission limits. Developers must strictly enforce that any custom instantiation configurations are a subset of default configurations when invoking code creation and storage APIs.

Denial of Service: Unbounded processing of address lists or unchecked input lengths can exhaust CPU, memory, or cause panics. Strict resource limits on address arrays, string lengths, and recursive call depth must be validated early.

Sandbox Escape: Sub-queries executing without state isolation can dirty the main execution context. Context isolation using clean, temporary cache layers is required to prevent state pollution.
