How to fix?
jsonwebtoken to version 9.0.0 or higher.
jsonwebtoken is a JSON Web Token implementation (symmetric and asymmetric)
Affected versions of this package are vulnerable to Improper Restriction of Security Token Assignment via the
secretOrPublicKey argument due to misconfigurations of the key retrieval function
jwt.verify(). Exploiting this vulnerability might result in incorrect verification of forged tokens when tokens signed with an asymmetric public key could be verified with a symmetric HS256 algorithm.
This vulnerability affects your application if it supports the usage of both symmetric and asymmetric keys in
jwt.verify() implementation with the same key retrieval function.
