- More information:
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.
