Ubiquiti Security Advisory Bulletins + NVD
Ubiquiti publishes Security Advisory Bulletins on its community site (community.ui.com), but there is no machine-readable feed and its CVEs are coordinated through HackerOne rather than a single Ubiquiti CNA — so VulniPulse ingests them from NVD (keyword-filtered to Ubiquiti) and links each CVE back to its community.ui.com bulletin when referenced. Covers UniFi Network / UniFi OS, the Dream Machine line (UDM/UDR/UCG), UniFi Protect, Access, Talk and Connect, plus EdgeRouter, EdgeSwitch, UISP and AmpliFi — an enormous internet-facing prosumer + SMB fleet that repeatedly ships max-severity (CVSS 10.0) flaws.
