Information Exposure Symfony is a PHP framework for web and console applications and a set of reusable PHP components. The ability to enumerate users was possible without relevant permissions due to different handling depending on whether the user existed or not when attempting to use the switch users functionality. We now ensure that status codes are returned whether the user exists or not if a user cannot switch to a user or if the user does not exist.
