What it is

VitaFit cloud API before 2026-10-30 contained a stored cross-site scripting vulnerability that allows authenticated attackers to upload an SVG image containing malicious JavaScript to the shared storage bucket. Attackers can exploit the application's failure to restrict scripts or force downloads for image/svg+xml content, causing the JavaScript to execute when a victim opens the file via direct browser navigation.
