Package : lxml
CVE ID : CVE-2021-28957
Debian Bug : 985643

Kevin Chung discovered that lxml, a Python binding for the libxml2 and
libxslt libraries, did not properly sanitize its input. This would
allow a malicious user to mount a cross-site scripting attack.

For the stable distribution (buster), this problem has been fixed in
version 4.3.2-1+deb10u3.

We recommend that you upgrade your lxml packages.

For the detailed security status of lxml please refer to
its security tracker page at:
