What You Should Do in Advance of Patch Availability
Due to the nature of the vulnerability, the security team has decided to
pre-announce that a fix is upcoming before disclosing the details. This
is to ensure that concerned users can plan around the release. As the
fix being published will make the details of the vulnerability public,
we are recommending that all users plan a maintenance window for the 60
minutes following the announcement in which to install the fix.
Meanwhile, we STRONGLY recommend that you take the following steps to
protect your site:
1. Make sure that the Zope/Plone service is running with with minimum
privileges. Ideally, the Zope and ZEO services should be able to
write only to log and data directories.
2. Use an intrusion detection system that monitors key system resources
for unauthorized changes.
3. Monitor your Zope, reverse-proxy request and system logs for unusual
activity.
These are standard precautions that should be employed on any production
system.

Python packages that may be installed by editing a buildout
configuration file and running buildout. Patching is generally easy and
quick to accomplish.
*Q: How were these vulnerability found?

Plone Security team. A subset were reported by users. More details will
be available upon release of the patch.

already been developed. Can I get the fix before the release date?*
A: No. The patch will be made available to *all users at the same time*.
There are no exceptions.
*Q: If the patch has been developed already, why isn't it made available
