For release 1.8.0, and test releases with PIV enabled prior to 1.8.0, the PIV application could accept invalid keys for authentication of the admin key. This could lead to compromise of the integrity of the data stored in the application. An attacker without access to the proper administration key would be able to generate new keys and overwrite certificates. Such an attacker would not be able to read-out or extract existing private data, nor would they be able to gain access to cryptographic operations that would normally require PIN-based authentication. The issue is fixed in piv-authenticator 0.3.9, and in Nitrokey's firmware 1.8.1.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":4.0},"cwes":["CWE-287"],"references":["https://github.com/Nitrokey/nitrokey-3-firmware/releases/tag/v1.8.1","https://github.com/Nitrokey/nitrokey-3-firmware/security/advisories/GHSA-jfhm-ppq8-7hgx","https://www.nitrokey.com/blog/2025/nitrokey-3-firmware-v181-security-update"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:59:18.731010617+00:00"},"epss":{"cve":"CVE-2025-25201","score":0.00141,"percentile":0.03437,"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).
