SCA: security update for weasyprint (GHSA-jf6q-chmf-3h3v)

medium Tenable Self-Hosted Container Security Plugin ID 447848

Description

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

- WeasyPrint helps web developers to create PDF documents. Prior to 70.0, server-side applications that
configure a restrictive url_fetcher and pass attacker-influenced values to HTML.write_pdf() can have the
restriction bypassed through the xmp_metadata or stylesheets options. In weasyprint/pdf/init.py,
xmp_metadata calls select_source() without the document url_fetcher, allowing an accessible local file to
be read and embedded verbatim in the output PDF. In weasyprint/document.py, stylesheets constructs CSS()
without the document url_fetcher, allowing local or internal resource loading and propagating the
permissive fetcher through nested CSS imports and url() references. The stylesheets channel applies
fetched resources but does not by itself disclose stylesheet comments verbatim. This issue is fixed in
version 70.0. (CVE-2026-55073)

Solution

Update the weasyprint library and its related packages to version 70.0 or later.
