Details

cross-site inclusion (XSSI) of files in jupyter-server ### Impact 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". ### Patches Jupyter Server 2.7.2 ### Workarounds Use lower performance `--ContentsManager.files_handler_class=jupyter_server.files.handlers.FilesHandler`, which implements the correct checks. ### References Upstream patch for CVE-2019-9644 was not applied completely, leaving part of the vulnerability open.
