Description: Vulnerabilities related to JSON Web Tokens (JWT) are a set of weaknesses that can arise due to improper validation of these tokens. JWTs are an open standard (RFC 7519) that allows secure transmission of information between parties as a JSON object. This object can be verified and trusted because it is digitally signed. However, if not implemented correctly, JWTs can be susceptible to attacks such as data manipulation, identity spoofing, and unauthorized access. Common vulnerabilities include lack of signature validation, use of insecure algorithms, and exposure of sensitive information in the token’s payload. Proper implementation of JWT validation is crucial to ensure the security of applications that rely on them, as poor management can lead to significant security breaches. Therefore, it is essential for developers to understand the security implications associated with the use of JWTs and adopt best practices to mitigate these risks.
