CVE-2026-54380 Details
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.
A stored cross-site scripting vulnerability has been identified in the VitaFit cloud API, affecting versions prior to 2026-10-30. This vulnerability allows authenticated users to upload SVG files containing malicious JavaScript to a shared storage bucket. The issue arises from the application's failure to properly restrict scripts or enforce download prompts for image/svg+xml files. As a result, the JavaScript executes when the file is opened in a browser. The vulnerability was not present in the Android application, which used a native image renderer that prevented script execution.
VitaFit has removed the endpoint that provided AWS credentials, and the current upload process rejects SVG files while still allowing regular PNG images.
