Descriptions

jupyter-server is the backend for Jupyter web applications. Improper cross-site credential checks on `/files/` URLs could allow exposure of certain file contents, or accessing files when opening untrusted files via "Open image in new tab". This issue has been addressed in commit `87a49272728` which has been included in release `2.7.2`. Users are advised to upgrade. Users unable to upgrade may use the lower performance `--ContentsManager.files_handler_class=jupyter_server.files.handlers.FilesHandler`, which implements the correct checks.

jupyter-server es el backend de las aplicaciones web de Jupyter. Las comprobaciones de Improper Cross-Site Credential en las URL `/files/` podrían permitir la exposición de ciertos contenidos de archivos o el acceso a archivos al abrir archivos que no son de confianza a través de "Abrir imagen en una pestaña nueva". Este problema se solucionó en el commit "87a49272728" que se incluyó en la versión "2.7.2". Se recomienda a los usuarios que actualicen. Los usuarios que no puedan actualizar pueden usar `--ContentsManager.files_handler_class=jupyter_server.files.handlers.FilesHandler` de menor rendimiento, que implementa las comprobaciones correctas.
