Vulnerability Detail
The Image Import function in XWiki through version 10.7 is vulnerable to cross-site scripting (XSS) attacks.

The Image Import function does not properly sanitize user-supplied input, allowing an attacker to craft a specially crafted image file that includes malicious scripts. When this image file is imported into XWiki, the malicious scripts are executed in the context of the user's browser, potentially leading to unauthorized access, data theft, or other malicious activities.
