Jupyter Core is a package for the core common functionality of Jupyter projects. When using Jupyter Core prior to version 5.8.0 on Windows, the shared %PROGRAMDATA%
directory is searched for configuration files (SYSTEM_CONFIG_PATH
and SYSTEM_JUPYTER_PATH
), which may allow users to create configuration files affecting other users. Only shared Windows systems with multiple users and unprotected %PROGRAMDATA%
are affected. Users should upgrade to Jupyter Core version 5.8.0 or later to receive a patch. Some other mitigations are available. As administrator, modify the permissions on the %PROGRAMDATA%
directory so it is not writable by unauthorized users; or as administrator, create the %PROGRAMDATA%\jupyter
directory with appropriately restrictive permissions; or as user or administrator, set the %PROGRAMDATA%
environment variable to a directory with appropriately restrictive permissions (e.g. controlled by administrators or the current user).
