Definition ∞ An eval injection bug is a security flaw where an application incorrectly processes user-supplied data, allowing an attacker to execute arbitrary code within the system. This vulnerability arises when user input is directly passed to an evaluation function without proper validation. Such a flaw can lead to severe security breaches and unauthorized system control.
Context ∞ In crypto news, reports on eval injection bugs often relate to exploits found in smart contracts, decentralized applications, or web interfaces interacting with blockchain systems. These vulnerabilities can result in the theft of digital assets, manipulation of protocol logic, or complete compromise of user accounts. Awareness of such bugs is crucial for developers and users navigating the digital asset security landscape.
