Description OSIDB Bzimport 2025-04-23 19:29:14 UTC

AIA (Application-initiated actions) could be used to circumvent required actions configured by an administrator to be performed by a user upon signing in. This could lead to the user circumventing requirements such as setting up 2FA.

   - A user account that has been required by an administrator to perform a
   required action.
   - The same user passing in a URL parameter during the sign in process.
