Recurring patterns

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

Cryptography: Signature verification APIs previously returned simple booleans on mismatch or deserialization errors instead of triggering immediate transaction abortion, leading to silent authentication bypasses. Enforcing immediate panic or VM abort on verification failure is critical.

Access Control: Token mappers lacked proper validation of transient pending states during initialization, allowing double-issuance of tokens or unauthorized overwriting of storage keys. Tracking transition states explicitly prevents re-entrancy and state corruption during token deployment.

Auth Bypass: The presence of dangerous VM APIs that allowed execution of transactions on a destination context on behalf of the original caller presented severe privilege escalation vectors, requiring their complete removal from the framework.
