      "value": "jupyterlab is an extensible environment for interactive and reproducible computing, based on the Jupyter Notebook Architecture. 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."

Antes de la versión 4.4.8, los enlaces generados con maquetadores LaTeX en archivos Markdown y celdas Markdown en JupyterLab y Jupyter Notebook no incluían el atributo noopener. Se considera que esto no tiene impacto en las instalaciones predeterminadas. Teóricamente, los usuarios de extensiones de terceros para renderizado de LaTeX podrían encontrarse vulnerables a ataques de reverse tabnabbing si los enlaces generados por esas extensiones incluían target=_blank (no se conocen tales extensiones en el momento de la redacción) y hicieran clic en un enlace generado en LaTeX (típicamente visiblemente diferente de otros enlaces).
