An XSS vulnerability in the Mailman 2.1 web UI has been reported and
assigned CVE-2018-5950 which is not yet public.
I plan to release Mailman 2.1.26 along with a patch for older releases
to fix this issue on Feb 4, 2018. At that time, full details of the
vulnerability will be public.
This is advance notice of the upcoming release and patch for those that
need a week or two to prepare. The patch will be small and only affect
one module.
