CVE-2026-54376 · Severity: high · CVSS 8.2 · Published 2026-11-04

Technical details

The vulnerability is an insecure custom URI scheme (vitafit://vtio.cn) used for OAuth callback handling in the Fitbit integration. A malicious application can register the same URI scheme to intercept the 30-day Fitbit authorization token containing weight scope delivered in the callback URL, gaining access to the victim's Fitbit Body API. This is a local attack requiring the user to trigger the Fitbit login flow while the malicious app is installed, but no elevated privileges are needed.
