The LAContext class for Biometric (TouchID) validation allows authentication bypass by overriding the LAContext return Boolean value to be \"true\" because the kSecAccessControlUserPresence protection mechanism is not used. In other words, an attacker could authenticate with an arbitrary fingerprint.  NOTE: the vendor indicates that this is not an attack of interest within the context of their threat model, which excludes iOS devices on which a jailbreak has occurred","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:P/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":6.3},"cwes":["CWE-287"],"references":["https://gist.github.com/tanprathan/f5133651e438b2ad1b39172d52b56115","https://gist.github.com/tanprathan/f5133651e438b2ad1b39172d52b56115"],"products":["linecorp:line"],"source":"nvd","synced_at":"2026-10-19T20:52:03.425131697+00:00"},"epss":{"cve":"CVE-2018-13434","score":0.00358,"percentile":0.29521,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
