CVE-2018-19351 (opens in a new tab)How to fix?
Upgrade Ubuntu:18.04 jupyter-notebook to version 5.2.2-1ubuntu0.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream jupyter-notebook package and not the jupyter-notebook package as distributed by Ubuntu.
See How to fix? for Ubuntu:18.04 relevant fixed versions and status.
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.
