Potential authentication and CSRF tokens leak in JupyterLab

CVE-2024-22421

What is CVE-2024-22421?

A vulnerability exists in JupyterLab, a widely used interactive computing environment, where users with outdated jupyter-server versions may unintentionally expose their Authorization and XSRFToken tokens through malicious links. This poses a significant risk as attackers can leverage this data to exploit user accounts. JupyterLab has released updates in versions 4.1.0b2, 4.0.11, and 3.6.7 to address this issue. Users are strongly recommended to upgrade their jupyter-server to version 2.7.2 or later, which includes a fix for a critical redirect vulnerability. Awareness and immediate action are essential to safeguard against unauthorized access.
