A Layer Two vulnerability refers to a security weakness discovered within a scaling solution built on top of a main blockchain, commonly known as Layer One. These vulnerabilities can exist in smart contracts, off-chain protocols, or bridges that connect Layer Two networks to Layer One. Exploiting such a flaw could lead to loss of funds, data manipulation, or denial of service within the Layer Two environment. They represent a specific security concern for scalability solutions.
