CVE-2021-21424 · Prevent user enumeration using Guard or the new Authenticator-based Security

Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.

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 403s are returned whether the user exists or not if a user cannot switch to a user or if the user does not exist. The patch for this issue is available for branch 3.4.
