A token approval flaw refers to a security vulnerability within a smart contract or decentralized application that allows unauthorized access to a user’s digital tokens. This flaw typically arises from improper implementation of token spending permissions, potentially enabling malicious actors to drain funds from approved wallets. Such vulnerabilities represent a significant risk to user assets and the integrity of decentralized protocols. It often results from errors in contract code or logic.
