Summary
cross-site inclusion (XSSI) of files in jupyter-server
Details

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
