Zope · Zope · CVE-2023-42458
**Name of the Vulnerable Software and Affected Versions**
Zope versions prior to 4.8.10 and 5.8.5
**Description**
Zope is an open-source web application server with a stored cross site scripting vulnerability for SVG images. The vulnerability can be exploited when an attacker uploads an image and tricks a user into following a specially crafted link. Note that an image tag with an SVG image as source is never vulnerable, even when the SVG image contains malicious code.
**Recommendations**
For Zope versions prior to 4.8.10, update to version 4.8.10 to resolve the issue.
For Zope versions prior to 5.8.5, update to version 5.8.5 to resolve the issue.
As a temporary workaround, make sure the `Add Documents, Images, and Files` permission is only assigned to trusted roles. By default, only the Manager has this permission.
