Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Trade execution lacked a check that the order sender is a registered valid sender, allowing unauthorized parties to execute trades on behalf of others.
Auth Bypass: Order validation did not enforce expiration timestamps, enabling replay of expired orders and potentially executing stale trades.
Logic Error: Reward calculation in withdraw could underflow, causing transaction reverts that lock user tokens permanently.
