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.","epss":null,"exploits":[{"kind":"exploit","source":"CNA: VulnCheck","url":"https://github.com/je-lv/vitafit-security-research"}],"kev":null,"metrics":[{"score":9.3,"severity":"critical","source":"CNA: VulnCheck","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},{"score":9.8,"severity":"critical","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},{"score":9.3,"severity":"critical","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","version":"4.0"},{"score":9.8,"severity":"critical","source":"NVD: disclosure@vulncheck.com","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793834268523,"publishedAt":1793831019111,"references":[{"source":"CNA: VulnCheck","tags":["technical-description","exploit"],"url":"https://github.com/je-lv/vitafit-security-research"},{"source":"CNA: VulnCheck","tags":["product"],"url":"https://play.google.com/store/apps/details?id=com.vt.vitafit"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/vitafit-cloud-api-authentication-bypass-via-post-front-login-sns"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://github.com/je-lv/vitafit-security-research"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://play.google.com/store/apps/details?id=com.vt.vitafit"},{"source":"disclosure@vulncheck.com","tags":[],"url":"https://www.vulncheck.com/advisories/vitafit-cloud-api-authentication-bypass-via-post-front-login-sns"}],"remediation":[],"revision":"83d2b1da3fae9d0b80cc1f6fe19a27faa4564a4a769524e35b031fc71caa77de","sources":[{"modifiedAt":1793831019111,"name":"CNA: VulnCheck","retrievedAt":1793833900029,"url":"https://www.cve.org/CVERecord?id=CVE-2026-54384"},{"modifiedAt":1793834268523,"name":"NVD","retrievedAt":1793838308571,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54384"}],"ssvc":null,"status":"published","title":"VitaFit Cloud API Authentication Bypass via POST /front/login/sns/","updatedAt":1793838308571}
