Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Inconsistent state restoration during pool unpausing allowed operations to resume under incorrect conditions, effectively bypassing intended pausing restrictions. Ensure all state variables governing borrowing and depositing operations are thoroughly validated and correctly restored upon calling unpause().
Auth Bypass: Enforcing validation rules inside internal helpers rather than at the external boundary can lead to authorization and limit bypasses depending on the execution path. Moving borrow cap checks to external entry points ensures that they cannot be evaded via alternative execution flows.
