Zope versions prior to versions 4.6.3 and 5.3 have a remote code execution security issue. In order to be affected, one must use Python 3 for one's Zope deployment, run Zope 4 below version 4.6.3 or Zope 5 below version 5.3, and have the optional `Products.PythonScripts` add-on package installed. By default, one must have the admin-level Zope \"Manager\" role to add or edit Script (Python) objects through the web. Only sites that allow untrusted users to add\u002Fedit these scripts through the web are at risk. Zope releases 4.6.3 and 5.3 are not vulnerable. As a workaround, a site administrator can restrict adding\u002Fediting Script (Python) objects through the web using the standard Zope user\u002Frole permission mechanisms. Untrusted users should not be assigned the Zope Manager role and adding\u002Fediting these scripts through the web should be restricted to trusted users only. This is the default configuration in Zope.","Zope is an open-source web application server. Zope versions prior to versions 4.6.3 and 5.3 have a remote code execution security issue.
