Yubico YubiKey

AI-generated from public sourcesAuto-generated by 0-Doubt from public vendor materials. Not verified by the vendor or an analyst. Check the freshness indicator.Lowest independence — unverified. A higher label means a more independent source — not a better product.How trust works →Secure coding rating: 0/100How this score is computedA product with no known CVEs starts at a neutral score and climbs the longer it goes without one; a product with known CVEs is penalized by severity instead. This one has 28 known CVEs (vendor-level match — see the CVE list below) and is tracked as ~39 days old in our catalog (a stand-in for real release date, which we don't track). The platform admin controls the formula's weights.

Known CVEs (28)About this listSourced from the public NVD database, matched by vendor name. Shown here at the vendor level — we don't track per-product/version data, so a listed CVE may affect a different product from this vendor, not necessarily this one. “New” means published within the last 30 days. “Actively exploited” means CISA's Known Exploited Vulnerabilities (KEV) catalog confirms real-world exploitation, not just a theoretical severity score.
