CVE-2024-22421

6.5 mediumEPSS 0.7%

Medium (6.5). EPSS 0.7% chance of exploitation in the next 30 days. Fixed in jupyterlab 3.6.7, 4.0.11.

JupyterLab is an extensible environment for interactive and reproducible computing, based on the Jupyter Notebook and Architecture. Users of JupyterLab who click on a malicious link may get their `Authorization` and `XSRFToken` tokens exposed to a third party when running an older `jupyter-server` version. JupyterLab versions 4.1.0b2, 4.0.11, and 3.6.7 are patched. No workaround has been identified, however users should ensure to upgrade `jupyter-server` to version 2.7.2 or newer which includes a redirect vulnerability fix.
