Name of the Vulnerable Software and Affected Versions Directus versions 9.0.0-alpha.4 through 9.4.1

Description The issue allows for unrestricted file upload of .html files in the media upload functionality, leading to a Cross-Site Scripting vulnerability. A low-privileged attacker can upload a crafted HTML file, such as a profile avatar, and when an admin or another user opens it, the XSS payload gets triggered.

Recommendations For versions 9.0.0-alpha.4 through 9.4.1, consider restricting the media upload functionality to prevent the upload of .html files until a patch is available. As a temporary workaround, avoid using the media upload feature for uploading profile avatars or other HTML files.
