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 an attacker to gain unauthorized access to an organization due to improper verification of a cryptographic signature. A token is accepted without its signature being fully verified, which could allow an attacker to join an organization without a valid invitation.
