CVE-2024-24770

vantage6 is an open source framework built to enable, manage and deploy privacy enhancing technologies like Federated Learning and Multi-Party Computation. Much like GHSA-45gq-q4xh-cp53, it is possible to find which usernames exist in vantage6 by calling the API routes `/recover/lost` and `/2fa/lost`. These routes send emails to users if they have lost their password or MFA token. This issue has been addressed in commit `aecfd6d0e` and is expected to ship in subsequent releases. Users are advised to upgrade as soon as a new release is available. There are no known workarounds for this vulnerability.

### Impact Much like https://github.com/vantage6/vantage6/security/advisories/GHSA-45gq-q4xh-cp53, it is possible to find which usernames exist in vantage6 by calling the API routes `/recover/lost` and `/2fa/lost`, which send emails to users if they have lost their password or MFA token. Usernames can be found by assessing response time differences, and additionally, they can be found because the endpoint gives a response "Failed to login" if the username exists. ### Patches No ### Workarounds No

vantage6 es un framework de código abierto creado para habilitar, administrar e implementar tecnologías que mejoran la privacidad, como el aprendizaje federado y la computación multipartita. Al igual que GHSA-45gq-q4xh-cp53, es posible encontrar qué nombres de usuario existen en vantage6 llamando a las rutas API `/recover/lost` y `/2fa/lost`. Estas rutas envían correos electrónicos a los usuarios si han perdido su contraseña o token MFA. Este problema se solucionó en el commit "aecfd6d0e" y se espera que se incluya en versiones posteriores. Se recomienda a los usuarios que actualicen tan pronto como esté disponible una nueva versión. No se conocen workarounds para esta vulnerabilidad.
