CVE-2023-41048 – plone.namedfile vulnerable to Stored Cross Site Scripting with SVG images

https://notcve.org/view.php?id=CVE-2023-41048

plone.namedfile allows users to handle `File` and `Image` fields targeting, but not depending on, Plone Dexterity content. Prior to versions 5.6.1, 6.0.3, 6.1.3, and 6.2.1, there is a stored cross site scripting vulnerability for SVG images. A security hotfix from 2021 already partially fixed this by making sure SVG images are always downloaded instead of shown inline. But the same problem still exists for scales of SVG images. Note that an image tag with an SVG image as source is not vulnerable, even when the SVG image contains malicious code. • http://www.openwall.com/lists/oss-security/2023/09/22/2 https://github.com/plone/Products.PloneHotfix20210518 https://github.com/plone/plone.namedfile/commit/188f66a4577021cf8f2bf7c0f5150f9b9573f167 https://github.com/plone/plone.namedfile/commit/217d6ce847b7171bf1b73fcb6c08010eb449216a https://github.com/plone/plone.namedfile/commit/f0f911f2a72b2e5c923dc2ab9179319cc47788f9 https://github.com/plone/plone.namedfile/commit/ff5269fb4c79f4eb91dd934561b8824a49a03b60 https://github.com/plone/plone.namedfile/security/advisories/GHSA-jj7c-jrv4-c65x • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') CWE-80: Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS) •
