summary JupyterLab is an extensible environment for interactive and reproducible computing, based on the Jupyter Notebook Architecture. From 4.0.0 to 4.5.6, the allow-list of extensions that can be installed from PyPI Extension Manager (allowed_extensions_uris) is not correctly enforced by JupyterLab. The PyPI Extension Manager was not contained to packages listed on the default PyPI index. This vulnerability is fixed in 4.5.7.

summary 
JupyterLab LaTeX typesetter links did not enforce `noopener` attribute
Links generated with LaTeX typesetters in Markdown files and Markdown cells in JupyterLab and Jupyter Notebook did not include the `noopener` attribute.

This is deemed to have no impact on the default installations. Theoretically users of third-party LaTeX-rendering extensions could find themselves vulnerable to reverse tabnabbing attacks if:
- links generated by those extensions included `target=_blank` (no such extensions are known at time of writing) and
- they were to click on a link generated in LaTeX (typically visibly different from other links).

For consistency with handling on other links, new versions of JupyterLab will enforce `noopener` and `target=_blank` on all links generated by typesetters. The former will harden the resilience of JupyterLab to extensions with lack of secure defaults in link rendering, and the latter will improve user experience by preventing accidental state loss when clicking on links rendered by LaTeX typesetters.
