vulnerability
Threshold Network's L2WormholeGateway contract contained a critical vulnerability allowing attackers to mint unlimited canonical L2 tBTC by exploiting the depositWormholeTbtc function through reentrancy via a malicious ERC20 token's transfer callback. The vulnerability was discovered via Immunefi bug bounty, patched by removing the vulnerable function and adding reentrancy protection, with no funds lost.
