Descriptions

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.

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.
