CVE-2023-22893
A remote attacker could forge an ID token that is signed using the 'None' type algorithm to bypass authentication and impersonate any user that use AWS Cognito for authentication.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.16%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
