UBUNTU-CVE-2025-55002: Medium severity ubuntu/jupyterlab vulnerability
JupyterLab Desktop is the cross-platform desktop application for JupyterLab. Prior to 4.6.2-1, JupyterLab Desktop for macOS shipped with Electron's RunAsNode fuse enabled, allowing ELECTRONRUNASNODE to execute arbitrary Node.js code in the application process. An attacker who can already execute code as the current user can therefore run code in JupyterLab Desktop's context and inherit TCC permissions previously granted to the application, including access to protected Documents, Desktop, or Downloads folders without another macOS prompt. Exploitation requires existing local code execution and prior TCC grants; it does not provide initial or remote code execution. Windows and Linux are not affected. This vulnerability is fixed in 4.6.2-1.

Event History
Frequently Asked Questions
Which systems are affected?
Only JupyterLab Desktop installations on macOS prior to 4.6.2-1 are affected. Windows and Linux are not affected.
What does an attacker need to exploit this issue?
An attacker must already be able to execute code as the current macOS user and JupyterLab Desktop must previously have received TCC permissions. This issue does not provide initial access or remote code execution.
What access could exploitation provide?
The attacker can execute arbitrary Node.js code in JupyterLab Desktop's process context and inherit TCC permissions granted to that application. This may include access to protected Documents, Desktop, or Downloads folders without an additional macOS prompt.
How can the issue be remediated?
Update JupyterLab Desktop for macOS to version 4.6.2-1, which fixes the vulnerability.
