vulnerability
A critical NFT bridge vulnerability in L1/L2 ERC721Bridge contracts allows attackers to steal deposited NFTs by exploiting inadequate token validation—an attacker can create a worthless L2 token, call withdrawTo() to burn it, and trigger finalizeERC721Withdrawal() on L1 without proper L1-L2 token correspondence checks, enabling theft of any NFT in the bridge contract.
