Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: High: There is a total loss of confidentiality, resulting in all information within the Vulnerable System being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

Exploitation evidence

Disclosed: evidence found.
CVE published 4 Nov 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 5 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

A fixed version of the VitaFit cloud API was released on 2026-10-30 that addresses this vulnerability. Users and administrators should upgrade to this version or later to remediate the issue. Since this is a cloud service, the vendor manages remediation on the server side. Verify with the vendor advisory that the service is updated accordingly.

Description

CVE-2026-54383 is a vulnerability in the VitaFit cloud API by Shenzhen Shine Industrial Co., Ltd. affecting versions before 2026-10-30. It allows any authenticated user to access the GET /front/relation/search/ endpoint without proper authorization, exposing personally identifiable information (PII) and health-related profile data. The exposed data includes user identifiers, emails, birthdays, gender, height, weight goals, phone numbers, and Firebase UIDs. The vulnerability was fixed in the version released on 2026-10-30.

Impact

The vulnerability allows unauthorized access to sensitive personal and health-related information of users, including identifiers, emails, birthdays, gender, height, weight goals, phone numbers, and Firebase UIDs. This exposure can lead to privacy violations and potential misuse of personal data. There is no indication of active exploitation in the wild at this time.

Summary

The VitaFit cloud API contained an excessive data exposure vulnerability due to missing authorization checks on the GET /front/relation/search/ endpoint. Authenticated users could exploit this flaw to enumerate the user directory by using overlapping alphanumeric search terms, thereby harvesting sensitive PII and health-related information of other users. This issue affects all versions prior to 2026-10-30. The vendor has fixed the vulnerability in the update released on 2026-10-30. The vulnerability has a CVSS 4.0 score of 7.1, indicating high severity, with network attack vector, low attack complexity, no privileges required beyond authentication, and high impact on confidentiality.
