Weak JSON Web Token (JWT) signing secret generation in YMFE YApi through 1.9.2 allows recreation of other users' JWT tokens. This occurs because Math.random in Node.js is used as a source of randomness in jwt signing. Math.random does not provide cryptographically secure random numbers. This has been patched in version 1.9.3.
