Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Access Control: Role-based mint/burn access was replaced with an immutable adapter to prevent privilege escalation; similar role-based patterns may persist elsewhere.
Access Control: Initialization admin role assignment was front-runnable; explicit parameterization is required to avoid attacker-controlled admin.
Access Control: Cross-chain deposits lacked source-chain authorization; a whitelist now restricts which EIDs can initiate deposits.
