CVE-2026-102904
NVD: JupyterLab is an extensible environment for interactive and reproducible computing, based on the Jupyter Notebook Architecture. NVD: The security impact requires that the PyPI Extension Manager is enabled, the account can call the extension API, and kernels and terminals are disabled or delegated to remote hosts; otherwise the user can already read files and make outbound requests directly. NVD: An authenticated user with extension API access can supply a pip requirements option to make the server read a local file or fetch an internal URL, and reflected parse errors can return the first unparsable line or response content.
