@jupyterlab/help-extension@4.5.5

@jupyterlab/help-extension is a JupyterLab - Help Extension

Affected versions of this package are vulnerable to Open Redirect in the CommandLinker class. An attacker can steal authentication tokens and gain unauthorized access to user accounts by convincing a user to open a malicious notebook file and interact with a malicious element, that execute arbitrary scripts. This graphical element can be made indistinguishable from legitimate ones. The exploit may allow reading, modifying, or creating files, accessing running kernels, and creating terminals for shell access.

Note: The upgraded versions also include an option to disable command linking completely by setting

{
  "@jupyterlab/apputils-extension:sanitizer": {
    "allowCommandLinker": false
  }
}

Upgrade @jupyterlab/help-extension to version 4.5.7 or higher.
