CVE-2024-41952
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedZitadel is an open source identity management system. ZITADEL administrators can enable a setting called "Ignoring unknown usernames" which helps mitigate attacks that try to guess/enumerate usernames. If enabled, ZITADEL will show the password prompt even if the user doesn't exist and report "Username or Password invalid". Due to a 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 exist within ZITADEL, since the error message shows "object not found" instead of the generic error message. This vulnerability is fixed in 2.58.1, 2.57.1, 2.56.2, 2.55.5, 2.54.8, and 2.53.9.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.53.92.54.82.55.5
2.58.1 (or latest available 2.x stable release for your major version branch)
- Identify the currently running Zitadel version using the admin console or API
- Determine which version branch you are on (2.53.x, 2.54.x, 2.55.x, or 2.56.x)
- Review the release notes for the target fixed version to check for any migration requirements
- Backup the Zitadel database and configuration before upgrading
- Upgrade Zitadel to version 2.53.9, 2.54.8, 2.55.5, 2.56.2, 2.57.1, or 2.58.1 (prefer the latest stable release for your major version)
- After upgrade, verify the 'Ignoring unknown usernames' setting is still enabled in the admin console under security settings
- Test the login flow with a non-existent username to confirm it returns the generic error message rather than 'object not found'
