Arch Linux Security Advisory ASA-202108-10
=========================================
Severity: High
Date    : 2021-08-10
CVE-ID  : CVE-2021-32797
Package : jupyterlab
Type    : cross-site scripting
Remote  : Yes
Link    : https://security.archlinux.org/AVG-2266

Summary
======
The package jupyterlab before version 3.1.4-1 is vulnerable to cross-site scripting.

Resolution
=========
Upgrade to 3.1.4-1.

# pacman -Syu "jupyterlab>=3.1.4-1"

The problem has been fixed upstream in version 3.1.4.

Workaround
=========
None.

Description
==========
In JupyterLab before version 3.1.4, untrusted notebooks can execute
code on load. In particular JupyterLab doesn't sanitize the action
attribute of the HTML 
 element. Using this it is possible to
trigger the form validation outside of the form itself. This is a
remote code execution, but requires user action to open a notebook.

Impact
=====
An attacker could perform remote code execution using a maliciously
crafted notebook file.
