Summary
The VitaFit cloud API, before 2026-10-30, lets a logged-in attacker upload an SVG image with malicious JavaScript to the shared storage bucket, reached remotely over the network. The script runs in a victim's browser when they open the file directly, which requires that user to take action.
Read the original description
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.
What to do
Upgrade to a fixed version: 2026-10-30.
