"Several vulnerabilities have been discovered in jupyter-notebook.

CVE-2018-8768

A maliciously forged notebook file can bypass sanitization to execute
JavaScript in the notebook context. Specifically, invalid HTML is
'fixed' by jQuery after sanitization, making it dangerous.

CVE-2018-19351

allows XSS via an untrusted notebook because nbconvert responses are
considered to have the same origin as the notebook server.

CVE-2018-21030

jupyter-notebook 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.

For Debian 9 stretch, these problems have been fixed in version
4.2.3-4+deb9u1.

We recommend that you upgrade your jupyter-notebook packages.
