Description: Incorrect security configuration in JavaScript is a vulnerability that arises from inadequate security settings in JavaScript applications. This vulnerability can allow attackers to exploit weaknesses in the application, potentially leading to the exposure of sensitive data, execution of malicious code, or unauthorized access to resources. Incorrect security configurations may include lack of input validation, exposure of sensitive information in source code, or improper implementation of security policies such as Content Security Policy (CSP). The dynamic nature of JavaScript, which runs in the client’s browser, makes these configurations particularly critical, as any mistake can be exploited by an attacker to compromise the application’s security. Therefore, it is essential for developers to follow security best practices and conduct regular audits to identify and correct inadequate configurations, thus ensuring the integrity and confidentiality of the data handled by their applications.
