Can you explain this vulnerability to me?
CVE-2026-2276 is a Reflected Cross-Site Scripting (XSS) vulnerability in the Wix web application, specifically in the endpoint https://manage.wix.com/account/account-settings that handles SVG image uploads.
The vulnerability occurs because this endpoint does not properly sanitize the content of uploaded SVG files. An authenticated attacker can upload an SVG file containing embedded JavaScript code.
When other users view the uploaded image, the malicious script is executed in their browser context, allowing arbitrary code execution.
