Callback Authorization Flaw denotes a security vulnerability in a smart contract where external functions invoked during a transaction lack proper permission checks. This oversight allows unauthorized entities to execute privileged operations by manipulating the flow of control after an initial call. Such flaws can lead to asset theft or unintended state changes within the protocol.
Context
Reports of callback authorization flaws frequently appear in post-mortem analyses of smart contract exploits, particularly in decentralized finance applications. The ongoing effort to enhance smart contract security involves rigorous auditing and formal verification methods to detect these subtle yet critical vulnerabilities. Developers continuously refine coding practices to prevent reentrancy and similar authorization bypasses.
