Untrusted users should not be assigned the Zope Manager role and adding/editing Zope Page Templates through the web should be restricted to trusted users only.\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in the [Zope issue tracker](https://github.com/zopefoundation/Zope/issues)\n* Email us at [security@plone.org](mailto:security@plone.org)\n",
