BNB Chain DEX Router Drained of $92,000 in Exploit

A security researcher, ExVul, reported an exploit on BNB Chain where approximately 62.28 WBNB was extracted from a DEX router.

The incident involved existing token approvals and a suspected failure to verify a Uniswap V3-style swap callback.

The attack mechanism centered on the router's handling of callbacks, which allowed an attacker to use previously granted spending permissions for unauthorized transfers.
