Hi,
The following vulnerability was published for jupyter-notebook.
CVE-2022-29238[0]:
| Jupyter Notebook is a web-based notebook environment for interactive
| computing. Prior to version 6.4.12, authenticated requests to the
| notebook server with `ContentsManager.allow_hidden = False` only
| prevented listing the contents of hidden directories, not accessing
| individual hidden files or files in hidden directories (i.e. hidden
| files were 'hidden' but not 'inaccessible'). This could lead to
| notebook configurations allowing authenticated access to files that
| may reasonably be expected to be disallowed. Because fully
| authenticated requests are required, this is of relatively low impact.
| But if a server's root directory contains sensitive files whose only
| protection from the server is being hidden (e.g. `~/.ssh` while
| serving $HOME), then any authenticated requests could access files if
| their names are guessable. Such contexts also necessarily have full
| access to the server and therefore execution permissions, which also
| generally grants access to all the same files. So this does not
| generally result in any privilege escalation or increase in
| information access, only an additional, unintended means by which the
| files could be accessed. Version 6.4.12 contains a patch for this
| issue. There are currently no known workarounds.
