## Impact 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. ## Mitigations - upgrade to `jupyter_core>=5.8.1` (5.8.0 is patched but breaks `jupyter-server`) , or - 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) ## Credit Reported via Trend Micro Zero Day Initiative as ZDI-CAN-25932

### Summary A permission verification flaw in Navidrome allows any authenticated regular user to bypass authorization checks and perform administrator-only transcoding configuration operations, including creating, modifying, and deleting transcoding settings. ### Details Navidrome supports transcoding functionality which, although disabled by default, should restrict configuration operations to administrators only. However, the application fails to properly validate whether a user has administrative privileges when handling transcoding configuration requests. The vulnerability exists in the API endpoints that manage transcoding settings. When a regular user sends requests to these endpoints, the application processes them without verifying if the user has administrative privileges, despite the JWT token clearly indicating the user is not an administrator (`"adm":false`). The affected endpoints include: - `POST /api/transcoding` (Create transcoding configuration) - `PUT /api/transcod...
