The Reset Code is used to reset the User PIN, but it is disabled by default. A flaw in the implementation of OpenPGP sets the Reset Code to a known value upon initialization. If the retry counter for the Reset Code is set to non-zero without changing the Reset Code, this known value can be used to reset the User PIN. To set the retry counters, the Admin PIN is required.","severity":{"version":"3.1","score":5.9,"vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N","level":"medium","assessor":"primary","from":"nvd"},"epss":{"day":"2026-11-11","score":0.00703,"percentile":0.53709,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"published":"2020-07-09T17:57:40Z","modified":"2026-06-17T02:55:53Z","products":[{"vendor":"yubico","product":"yubikey_5_nfc_firmware"}],"references":[{"url":"https://www.yubico.com/support/security-advisories/ysa-2020-05/","tags":["x_refsource_CONFIRM","x_transferred","Mitigation","Vendor Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2020-15000"},{"url":"https://github.com/advisories/GHSA-cg49-hhrx-hw69"}],"sources":{"cve":[{"id":"CVE-2020-15000","description":"A PIN management problem was discovered on Yubico YubiKey 5 devices 5.2.0 to 5.2.6.
