An insufficiently secured internal function allows session generation for arbitrary users.

HIGH 8.8EPSS 0.08%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.08%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

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.
