| Vector | AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
JupyterLab versions prior to 1.2.21
JupyterLab versions prior to 2.2.10
JupyterLab versions prior to 2.3.2
JupyterLab versions prior to 3.0.17
JupyterLab versions prior to 3.1.4
Description
In affected versions, an untrusted notebook can execute code on load, allowing for remote code execution. This requires user action to open a notebook. The issue arises from JupyterLab's failure to sanitize the action attribute of HTML
<form>, enabling the triggering of form validation outside the form itself.Recommendations
For versions prior to 1.2.21, update to version 1.2.21 or later.
For versions prior to 2.2.10, update to version 2.2.10 or later.
For versions prior to 2.3.2, update to version 2.3.2 or later.
For versions prior to 3.0.17, update to version 3.0.17 or later.
For versions prior to 3.1.4, update to version 3.1.4 or later.
