Prior to version 4.4.8, 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). This issue has been patched in version 4.4.8.","jupyterlab is an extensible environment for interactive and reproducible computing, based on the Jupyter Notebook Architecture.

The window.opener object records information about the original page that offered the link.  If an attacker can run script on the target page, then they could read or modify certain properties of the window.opener object, including the location property - even if the original and target site are not the same origin.  An attacker can modify the location property to automatically redirect the user to a malicious site, e.g. as part of a phishing attack.
