Package : wkhtmltopdf
Version : 0.12.5-1+deb10u1
CVE ID : CVE-2020-21365

It was found that wkhtmltopdf, a command line utility to render HTML
files into PDF, allowed local filesystem access by default. This update
disables local filesystem access, but it can be enabled if necessary
with the --enable-local-file-access or the --allow options.

For Debian 10 buster, this problem has been fixed in version
0.12.5-1+deb10u1.

We recommend that you upgrade your wkhtmltopdf packages.
