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 2.42.17), 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-434: Unrestricted Upload of File with Dangerous Type, where the product allows the upload or transfer of dangerous file types that are automatically processed within its environment. 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 users can upload their own avatar image and various image types are allowed. Due to a missing check, an attacker could upload HTML and pretend it is an image to gain access to the victim's account in certain scenarios. A possible victim would need to directly open the supposed image in the browser, where a session in ZITADEL needs to be active for this exploit to work. The exploit could only be reproduced if the victim was using Firefox. Chrome, Safari as well as Edge did not execute the code. ### Patches 2.x versions are fixed on >= [2.48.3](https://github.com/zitadel/zitadel/releases/tag/v2.48.3) 2.47.x versions are fixed on >= [2.47.8](https://github.com/zitadel/zitadel/releases/tag/v2.47.8) 2.46.x versions are fixed on >= [2.46.5](https://github.com/zitadel/zitadel/releases/tag/v2.46.5) 2.45.x versions are fixed on >= [2.45.5](https://github.com/zitadel/zitadel/releases/tag/v2.45.5) 2.44.x versions are fixed on >= [2.44.7](https://github.com/zitadel/zitadel/releases/tag/v2.44.7) 2.43.x versions are fixed on >= [2.43.11](https://github.com/zitadel/zitadel/releases/tag/v2.43.11) 2.42.x versions are fixed on >= [2.42.17](https://github.com/zitadel/zitadel/releases/tag/v2.42.17) ZITADEL recommends upgrading to the latest versions available in due course. ### Workarounds There is no workaround since a patch is already available. ### References None ### Questions If you have any questions or comments about this advisory, please email us at [security@zitadel.com](mailto:security@zitadel.com) ### Credits Thanks to Amit Laish – GE Vernova for finding and reporting the vulnerability.
