What is CVE-2026-54380?

The VitaFit Cloud API is susceptible to a stored cross-site scripting vulnerability that permits authenticated users to upload SVG images containing harmful JavaScript. This weakness stems from inadequate restrictions on scripts and the handling of image/svg+xml content. When a victim accesses the compromised file directly through their browser, the malicious JavaScript executes, potentially leading to various security issues.
