IBM API Connect 5.0.0.0 through 5.0.8.6 developer portal could allow a remote attacker to traverse directories on the system. An attacker could send a specially-crafted URL request containing "dot dot" sequences (/../) to view arbitrary files on the system. IBM X-Force ID: 163681.

IBM API Connect uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information.

IBM API Connect 5.0.0.0-5.0.8.3 Developer Portal does not enforce Two Factor Authentication (TFA) while resetting a user password but enforces it for all other login scenarios. IBM X-Force ID: 144483.

IBM API Connect 5.0.0.0, 5.0.8.4, 2018.1 and 2018.3.6 is vulnerable to CSV injection via the developer portal and analytics that could contain malicious commands that would be executed once opened by an administrator. IBM X-Force ID: 148692.
