What Are the Most Common Vulnerabilities Found in Smart Contracts?

Common vulnerabilities in smart contracts include reentrancy attacks, where a contract can be repeatedly called before the first invocation is finished, and improper access controls, which can allow unauthorized users to manipulate contract functions. Other issues include integer overflow and underflow, front-running, and denial of service attacks.

These vulnerabilities can lead to significant financial losses if not addressed.
