You are affected by this vulnerability if all of the following conditions apply: - You are using express-jwt - You do not have algorithms configured in your express-jwt configuration. - You are using libraries such as jwks-rsa as the secret. You can fix this by specifying algorithms in the express-jwt configuration. See linked GHSA for example. This is also fixed in version 6.0.0.
