Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/zitadel/zitadel

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-41952, inspect your project dependencies for Github.com/zitadel/zitadel:

inspect dependencies for github.com/zitadel/zitadel

Analyze the terminal output to locate any version of Github.com/zitadel/zitadel in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.53.9), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-203: Observable Discrepancy, where the product behaves differently or sends different responses under different circumstances in a way that is observable to an unauthorized actor. In Github.com/zitadel/zitadel, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact 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. ### Patches 2.x versions are fixed on >= [2.58.1](https://github.com/zitadel/zitadel/releases/tag/v2.58.1) 2.57.x versions are fixed on >= [2.57.1](https://github.com/zitadel/zitadel/releases/tag/v2.57.1) 2.56.x versions are fixed on >= [2.56.2](https://github.com/zitadel/zitadel/releases/tag/v2.56.2) 2.55.x versions are fixed on >= [2.55.5](https://github.com/zitadel/zitadel/releases/tag/v2.55.5) 2.54.x versions are fixed on >= [2.54.8](https://github.com/zitadel/zitadel/releases/tag/v2.54.8) 2.53.x versions are fixed on >= [2.53.9](https://github.com/zitadel/zitadel/releases/tag/v2.53.9) ZITADEL recommends upgrading to the latest versions available in due course. ### Workarounds There is no workaround since a patch is already available. ### Questions If you have any questions or comments about this advisory, please email us at [security@zitadel.com](mailto:security@zitadel.com)
