GMS-2020-37: Improper Authorization in @sap-cloud-sdk/core

September 3, 2020 (updated October 4, 2021)

Affected versions of @sap-cloud-sdk/core do not properly validate JWTs. The verifyJwt() function does not properly validate the URL from where the public verification key for the JWT can be downloaded. Any URL was trusted which makes it possible to provide a URL belonging to a manipulated JWT. Upgrade to or later.
