High (7.5) in strapi strapi. EPSS 4.1% chance of exploitation in the next 30 days. Fixed in @strapi/plugin-users-permissions 4.6.0.
Strapi through 4.5.5 does not verify the access or ID tokens issued during the OAuth flow when the AWS Cognito login provider is used for authentication. 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.
