CVE-2022-23540 Information

Description

In versions <=8.5.1 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 please update to version 9.0.0 which removes the default support for the none algorithm in the jwt.verify() method. There will be no impact if you update to version 9.0.0 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.
