HTML injection in Jupyter Notebook and JupyterLab leading to DOM Clobbering

### Impact The vulnerability depends on user interaction by opening a malicious notebook with Markdown cells, or Markdown file using JupyterLab preview feature. A malicious user can access any data that the attacked user has access to as well as perform arbitrary requests acting as the attacked user. ### Patches JupyterLab v3.6.8, v4.2.5 and Jupyter Notebook v7.2.2 were patched. ### Workarounds There is no workaround for the underlying DOM Clobbering susceptibility. However, select plugins

JupyterLab vulnerable to potential authentication and CSRF tokens leak

### Impact 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. ### Patches JupyterLab 4.1.0b2, 4.0.11, and 3.6.7 were patched. ### Workarounds 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. ### References Vulnerability reported by user @davwwwx via the [bug

JupyterLab vulnerable to SXSS in Markdown Preview

### Impact The vulnerability depends on user interaction by opening a malicious notebook with Markdown cells, or Markdown file using JupyterLab preview feature. A malicious user can access any data that the attacked user has access to as well as perform arbitrary requests acting as the attacked user. ### Patches JupyterLab v4.0.11 was patched. ### Workarounds Users can either disable the table of contents extension by running: ```bash jupyter labextension disable @jupyterlab/toc-extension

JupyterLab is a user interface for Project Jupyter which will eventually replace the classic Jupyter Notebook. In affected versions untrusted notebook can execute code on load. In particular JupyterLab doesn’t sanitize the action attribute of html `<form>`. 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.
