CVE-2023-44389: Stored cross site scripting via the title property in the Zope management interface
Zope is an open-source web application server. The title property, available on most Zope objects, can be used to store script code that is executed while viewing the affected object in the Zope Management Interface (ZMI). All versions of Zope 4 and Zope 5 are affected. Patches will be released with Zope versions 4.8.11 and 5.8.6
Impact
The title property, available on most Zope objects, can be used to store script code that is executed while viewing the affected object in the Zope Management Interface (ZMI) because the title property is displayed unquoted in the breadcrumbs element. All versions of Zope 4 and Zope 5 are affected.
Patches
Patches will be released with Zope versions 4.8.11 and 5.8.6
Workarounds
Make sure only Manager users can edit and view Zope objects in the Zope Management Interface. This is the default.
