Security audit finds critical risks in Morpho Blue's $11B cross-chain bridge

A security assessment of the Morpho Blue protocol's cross-chain bridge was published on October 13, 2026. The bridge facilitates liquidity movement between Ethereum and several layer-2 networks, handling over $10 billion in assets. The audit identified multiple security vulnerabilities in its design and architecture. The most severe risks include potential validator collusion, a lack of safeguards on upgrade mechanisms, and insufficient finality guarantees for transactions. These findings highlight systemic risks due to the bridge's central role in the high-value protocol.
