Possibility to generate a session for any user via the "ex:action" parameter after obtaining access to the JWT key

Vulnerability Description

An insufficiently secured internal function allows session generation for arbitrary users. The decodeParam function checks the JWT but does not verify which signing algorithm was used. As a result, an attacker can use the "ex:action" parameter in the VerifyUserByThrustedService function to generate a session for any user.
