Subject: bug#47319: python-lxml is vulnerable to CVE-2021-28957
Date: Mon, 22 Mar 2021 15:09:24 +0100	[thread overview]
Message-ID: <8e3d68f9e674d1556bf2ba6baff0e72c069a2673.camel@zaclys.net> (raw)

CVE-2021-28957	21.03.21 06:15
lxml 4.6.2 places the HTML action attribute into defs.link_attrs (in
html/defs.py) for later use in input sanitization, but does not do the
same for the HTML5 formaction attribute.

Upstream fixed it in 4.6.3 (
https://github.com/lxml/lxml/commit/2d01a1ba8984e0483ce6619b972832377f208a0d
), so we should probably upgrade to that.

Has lots of dependents so I suppose it needs grafting? Is that useful
and does it work for Python packages?
