Description: A security vulnerability in JavaScript refers to a weakness in the code or implementation of this programming language that can be exploited by attackers to compromise web applications. These vulnerabilities can arise from various sources, such as coding errors, misconfigurations, or flaws in application logic. The dynamic and flexible nature of JavaScript, which allows for DOM manipulation and real-time user interaction, makes it an attractive target for attackers. Common vulnerabilities include Cross-Site Scripting (XSS), where an attacker injects malicious scripts into web pages viewed by other users, and Cross-Site Request Forgery (CSRF), which tricks browsers into performing unauthorized actions on behalf of an authenticated user. Identifying and mitigating these vulnerabilities is crucial for the security of web applications, as they can lead to the exposure of sensitive data, account takeover, and other attacks that compromise the integrity and confidentiality of information. Therefore, it is essential for developers to implement secure coding practices and conduct regular vulnerability assessments to protect their applications from potential threats.
