How this kind of attack works

The contract's bookkeeping was wrong, for example the conversion between shares and assets, so the attacker redeemed far more than they put in.

Would a pre-payment check have helped

Needs other controls

Accounting and share-math bugs are contract-layer problems for code audits.
