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.
Jupyter Notebook before 5.5.0 does not use a CSP header to treat served files as belonging to a separate origin. Thus, for example, an XSS payload can be placed in an SVG document.
