Ecosystem-wide dependent count for version 5.8.1.
DescriptionGitHub Advisory
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).
AnalysisAI
A security vulnerability in Jupyter Core (CVSS 7.3) that allows users. High severity vulnerability requiring prompt remediation.
Technical ContextAI
CWE-427 (Uncontrolled Search Path). CVSS 7.3 indicates high severity. Affects Jupyter Core.
