Attackers can enumerate the publicly accessible bucket containing 129,947 objects, including 126,881 user-uploaded profile images, to access sensitive personal data without credentials.https://vulnfeed.org/cve/CVE-2026-54382/https://vulnfeed.org/cve/CVE-2026-54382/Wed, 04 Nov 2026 23:17:48 +0000VitaFit cloud API before 2026-10-30 contained an improper access control vulnerability in its Cognito-issued AWS role that allows authenticated attackers to perform s3:PutObject operations across the entire shared bucket instead of being restricted to their own folder. Attackers can overwrite other users' objects in the shared S3 bucket using credentials obtained via CVE-2026-54378, destroying original content without triggering deletion protections.https://vulnfeed.org/cve/CVE-2026-54384/https://vulnfeed.org/cve/CVE-2026-54384/Wed, 04 Nov 2026 22:23:39 +0000VitaFit cloud API before 2026-10-30 contained an authentication bypass vulnerability that allows remote attackers to obtain a full session for a victim's account by submitting a linked Google or Facebook account identifier to the POST /front/login/sns/ endpoint without providing proof of ownership from the identity provider. Attackers can forge a login using an identifier exposed through account enumeration to read and modify the victim's profile and delete the account's authentication record, preventing the legitimate user from logging in.https://vulnfeed.org/cve/CVE-2026-54383/https://vulnfeed.org/cve/CVE-2026-54383/Wed, 04 Nov 2026 22:21:46 +0000VitaFit cloud API before 2026-10-30 contained an excessive data exposure vulnerability that allows any authenticated user to query the GET /front/relation/search/ endpoint and retrieve PII and health-related profile information for user records. Attackers can enumerate the user directory using overlapping alphanumeric search terms to harvest identifiers, emails, birthdays, gender, height, weight goals, phone numbers, and Firebase UIDs.https://vulnfeed.org/cve/CVE-2026-54374/https://vulnfeed.org/cve/CVE-2026-54374/Wed, 04 Nov 2026 22:18:05 +0000VitaFit Android application (com.vt.vitafit) before 2.8.1.0 contains a hardcoded credentials vulnerability that allows attackers to extract confidential third-party integration secrets by decompiling the APK. Attackers can retrieve embedded WeChat, Tencent QQ, and Fitbit credentials from the decompiled application to abuse the active third-party application registrations.https://vulnfeed.org/cve/CVE-2026-54372/https://vulnfeed.org/cve/CVE-2026-54372/Wed, 04 Nov 2026 22:18:04 +0000VitaFit Android application (com.vt.vitafit) before 2.8.1.0 contains an insecure TLS/SSL certificate validation vulnerability that allows network-based attackers to intercept and modify HTTPS traffic by exploiting a custom X509TrustManager that trusts all certificates and a hostname verifier that accepts any hostname. Attackers can perform a man-in-the-middle attack to capture account sessions and health-related API data, and use a captured session to delete the account's authentication record and prevent legitimate login.https://vulnfeed.org/cve/CVE-2026-54378/https://vulnfeed.org/cve/CVE-2026-54378/Wed, 04 Nov 2026 22:09:16 +0000VitaFit cloud API before 2026-10-30 contained a broken access control vulnerability that allows any authenticated user to obtain temporary AWS credentials by calling the POST /front/user/s3/token/ endpoint. Attackers can use these improperly scoped credentials to list the shared storage bucket and read or overwrite other users' stored files, enabling unauthorized cross-user data access and manipulation.https://vulnfeed.org/cve/CVE-2026-54376/https://vulnfeed.org/cve/CVE-2026-54376/Wed, 04 Nov 2026 22:01:47 +0000VitaFit Android application (com.vt.vitafit) before 2.8.1.0 contains an insecure custom URI scheme vulnerability that allows a malicious application to intercept Fitbit login tokens by registering the same callback scheme (vitafit://vtio.cn). Attackers can capture the 30-day Fitbit authorization token with weight scope delivered in the callback URL to read, create, and delete the victim's weight and body-fat records via the Fitbit Body API.https://vulnfeed.org/cve/CVE-2026-54375/https://vulnfeed.org/cve/CVE-2026-54375/Wed, 04 Nov 2026 21:54:23 +0000VitaFit Android application (com.vt.vitafit) before 2.8.1.0 contains an insecure session management vulnerability that allows attackers to extract or intercept unencrypted m_session_id tokens stored in application backups, which remain valid for ten years. Attackers can use a stolen session token to read and modify the victim's account or delete the account's authentication record, preventing the legitimate owner from logging in again.
