A username enumeration issue was discovered in SquaredUp before version 4.6.0. The login functionality was implemented in a way that would enable a malicious user to guess valid username due to a different response time from invalid usernames.
The product behaves differently or sends different responses under different circumstances in a way that is observable to an unauthorized actor, which exposes security-relevant information about the state of the product, such as whether a particular operation was successful or not.
