vulnerability
A critical vulnerability in tBTC's L2WormholeGateway contract allowed attackers to mint unlimited Layer 2 tBTC tokens by exploiting the depositWormholeTbtc function through a reentrancy-like pattern in cross-chain bridging. The vulnerability was discovered via Immunefi bug bounty, patched before exploitation, and mitigated by removing the vulnerable function and adding reentrancy protection.
