medium Tenable Self-Hosted Container Security Plugin ID 422825

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Jupyter Notebook before 5.7.1 allows XSS via an untrusted notebook because nbconvert responses are
 considered to have the same origin as the notebook server. In other words, nbconvert endpoints can execute
 JavaScript with access to the server API. In notebook/nbconvert/handlers.py, NbconvertFileHandler and
 NbconvertPostHandler do not set a Content Security Policy to prevent this. (CVE-2018-19351)
