Description

IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to obtain an access token for another user due to improper authentication. The sign-in flow does not sufficiently verify the identity of the user completing it, which could allow another user's identity to be assumed.
