CVE-2026-40171

Red Hat Security Advisory: RHOAI 3.4.4 - Red Hat OpenShift AI

Description

A flaw was found in Jupyter Notebook and JupyterLab. A stored cross-site scripting (XSS) vulnerability in the help command linker can be exploited by an attacker who crafts a malicious notebook file. When a user interacts with this file, the XSS is triggered, allowing the attacker to steal authentication tokens. Successful exploitation can lead to a complete takeover of the Jupyter session, enabling arbitrary code execution and information disclosure.
