Description Avinash Hanwate 2023-01-11 05:05:10 UTC 
node-jsonwebtoken is a JsonWebToken implementation for node.js. For versions `<= 8.5.1` of `jsonwebtoken` library, if a malicious actor has the ability to modify the key retrieval parameter (referring to the `secretOrPublicKey` argument from the readme link of the `jwt.verify()` function, they can write arbitrary files on the host machine. Users are affected only if untrusted entities are allowed to modify the key retrieval parameter of the `jwt.verify()` on a host that you control. This issue has been fixed, please update to version 9.0.0.
