NOTE: this is different from CVE-2023-4177, which claims to be about \"some unknown processing of the component Multi-Factor Authentication Code Handler\" and thus cannot be correlated with other vulnerability information.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","score":9.1},"cwes":["CWE-287"],"references":["https://nvd.nist.gov/vuln/detail/CVE-2023-40260","https://seclists.org/fulldisclosure/2023/Aug/3","https://nvd.nist.gov/vuln/detail/CVE-2023-40260","https://seclists.org/fulldisclosure/2023/Aug/3"],"products":["empowerid:empowerid"],"source":"nvd","synced_at":"2026-10-19T21:39:14.809778102+00:00"},"epss":{"cve":"CVE-2023-40260","score":0.00628,"percentile":0.50128,"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).
