A UID is a manufacturer serial number sent in the clear on every read and is not intended to be secret or to authenticate the holder. Validating on the UID of the NTAG212 NFC chip alone is identification, not authentication, and the credential has no challenge-response capability that would resist copying.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[{"seq":210313,"id":"CVE-2026-75907","ts":1790275812997,"field":"cvss","old":null,"new":"7.5"},{"seq":210312,"id":"CVE-2026-75907","ts":1790275812997,"field":"severity","old":"none","new":"high"}]}
