How this kind of attack works
A bridge confirms on one chain and releases on another. When confirmation was bypassed, the attacker received assets on the target chain without depositing.
Would a pre-payment check have helped
Bridge mint/verification flaws happen inside the bridge and are addressed by its own security design and audits.
