Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Token Accounting: Redemption used _transfer instead of _burn, allowing redeemed tokens to remain in circulation and enabling double-spending or fund draining. This is the highest-impact historical flaw and the core invariant of the token contract.
Token Approval Manipulation: Old strategy allowance was not zeroed before closing positions, leaving a lingering approval that could be exploited to steal tokens via the stale strategy.
Business Logic Error: Minting fee was not applied to collateral when member tokens were insufficient, allowing users to evade fees and under-collateralize the system.
