Recurring patterns

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

Auth Bypass: Critical interest rate strategies can have their data parameters modified by unauthorized callers if strict caller-identity validation is omitted. Ensuring that only the authorized Liquidity Hub contract can invoke these state-modifying actions is crucial to prevent protocol-wide disruption.

Auth Bypass: Administrative and deficit-mitigation operations such as eliminateDeficit on the Hub are prone to unauthorized execution if they lack explicit access-control modifier enforcement.

Logic Error: Executing business validations like payFee or transferShares on stale parameters can permit actions based on outdated debt or interest balances. The system must force state accruals to occur prior to running any validation checks.
