CVE-2024-41952

Name of the Vulnerable Software and Affected Versions Zitadel versions prior to 2.53.9 Zitadel versions prior to 2.54.8 Zitadel versions prior to 2.55.5 Zitadel versions prior to 2.56.2 Zitadel versions prior to 2.57.1 Zitadel versions prior to 2.58.1

Description Zitadel is an open source identity management system. The system has a setting called "Ignoring unknown usernames" which helps mitigate attacks that try to guess or enumerate usernames. If enabled, Zitadel will show the password prompt even if the user doesn't exist and report "Username or Password invalid". However, due to an implementation change to prevent deadlocks calling the database, the flag would not be correctly respected in all cases, and an attacker would gain information if an account exists within Zitadel, since the error message shows "object not found" instead of the generic error message.
