CVE-2026-54375Shenzhen Shine Industrial Co., Ltd. VitaFit insufficient session expiration
CVE-2026-54375 is a insufficient session expiration in Shenzhen Shine Industrial Co., Ltd. VitaFit, rated high (8.6 on CVSS 4.0).
Why this priority: High severity, with no exploitation signal yet.
Published · Updated · NVD status: Deferred
What it is
Sessions stay valid long after they should end.
How it is reached
An attacker can exploit it by someone who can already run code or sign in on the machine, without an account, and nobody has to click anything.
What an attacker gains
A successful attack can read the data it protects, change data or behaviour and take it offline. In practice, this kind of flaw lets an attacker act as a signed-in user, or an administrator, without valid credentials.
Is it being exploited?
CISA's SSVC assessment notes a public proof of concept. EPSS estimates a 0.15% chance of exploitation activity in the next 30 days, higher than 4% of scored CVEs.
What to do
- Upgrade Shenzhen Shine Industrial Co., Ltd. VitaFit to 2.8.1.0 or later.
- Limit who can run code or sign in on the hosts that run it.
Description from NVD
VitaFit 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.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Sign-in, session and token handling. The flaw sits between anonymous callers and authenticated sessions.
- Identity providers and SSO. The flaw sits between anonymous callers and authenticated sessions.
Trust boundaries in play
- Host boundary. The attacker needs a foothold on the machine first; the flaw turns a small foothold into a bigger one.
- Between anonymous callers and authenticated sessions. An attacker who crosses it can act as a signed-in user, or an administrator, without valid credentials.
Questions to answer about your own systems
- Where does Shenzhen Shine Industrial Co., Ltd. VitaFit run in your systems, and at which version?
- Which of those hosts also run code or users you do not fully trust?
- What can it reach once compromised: which data stores, secrets and services?
