Use of a Broken or Risky Cryptographic Algorithm in jsonwebtoken
CVE-2022-23540
- jsonwebtoken
- org.webjars.npm:jsonwebtoken
Summary
Versions prior to 9.0.0 of `jsonwebtoken` library, lack of algorithm definition in the `jwt.verify()` function can lead to signature validation bypass due to defaulting to the `none` algorithm for signature verification. Users are affected if you do not specify algorithms in the `jwt.verify()` function. This issue has been fixed, which removes the default support for the none algorithm in the `jwt.verify()` method and you don’t need to allow for the `none` algorithm. If you need 'none' algorithm, you have to explicitly specify that in `jwt.verify()` options.
