QNAP PSIRT (security@qnap.com CNA) via NVD
QNAP is its own CVE Numbering Authority. VulniPulse ingests QNAP's CVEs from the NVD CNA feed (security@qnap.com), grouped by their official QSA advisory, and enriches each from the security-advisory page — the vendor's severity, affected apps/OS and the fixed build. Covers QTS, QuTS hero and QuTScloud (NAS operating systems), plus QVR, Qsync, HBS 3, Netatalk, Malware Remover, License Center and Photo/Video/Music Station — QNAP NAS are a relentless ransomware target (DeadBolt, Qlocker), so an alert-hungry community.
