Severity: Warning

Category: Security

Description

Do not use none as a validation algorithm for a JWT token. The none algorithm assumes that the token has been verified, which would allow attacker to create a token that would be automatically validated.

Never use the none algorithm, always use a valid algorithm as directed by the documentation.

Non-Compliant Code Examples

jwt.verify(token, secret, { algorithms: ['RS256', 'none'] }, func);
jwt.verify(token, secret, { algorithms: ['none', 'RS256'] }, func);

Compliant Code Examples

jwt.verify(token, secret, { algorithms: ['RS256', 'HS256'] }, func);
