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.
Latest Ubiquiti UniFi Network / OS advisories

A malicious actor with access to the network and high privileges could exploit an Improper Access Control vulnerability found in UniFi Network Application to escalate privileges within the UniFi Network Application.
Critical [CVE-2026-77540] malicious actor with access to the network and high privileges could exploit an Improper Input Validation vulnerability found in UniFi OS Server to execute a Command Injection on the host device
A malicious actor with access to the network and high privileges could exploit an Improper Input Validation vulnerability found in UniFi OS Server to execute a Command Injection on the host device.
Critical [CVE-2026-77536] UniFi OS Server: malicious actor with access to the network and low privileges could exploit an Improper Access Control vulnerability found in certain devices running UniFi OS to escalate privileges within such UniFi OS devices or instances
A malicious actor with access to the network and low privileges could exploit an Improper Access Control vulnerability found in certain devices running UniFi OS to escalate privileges within such UniFi OS devices or instances. Affected product named by the advisory: UniFi OS Server.
Critical [CVE-2026-77535] malicious actor with access to the network and high privileges could exploit an Improper Input Validation vulnerability found in UniFi Network Application to execute a Command Injection on an adopted device
A malicious actor with access to the network and high privileges could exploit an Improper Input Validation vulnerability found in UniFi Network Application to execute a Command Injection on an adopted device.
Critical [CVE-2019-25651] Ubiquiti UniFi Network Controller prior to 5.10.12 (excluding 5.6.42), UAP FW prior to 4.0.6, UAP-AC, UAP-AC v2, and UAP-AC…
Ubiquiti UniFi Network Controller prior to 5.10.12 (excluding 5.6.42), UAP FW prior to 4.0.6, UAP-AC, UAP-AC v2, and UAP-AC Outdoor FW prior to 3.8.17, USW FW prior to 4.0.6, USG FW prior to 4.4.34 uses AES-CBC encryption for device-to-controller communication, which contains cryptographic weaknesses that allow attackers to recover encryption keys from captured traffic. Attackers with adjacent network access can capture sufficient encrypted traffic and exploit AES-CBC mode vulnerabilities to derive the encryption keys, enabling unauthorized control and management of network devices. Affected products named by the advisory: UniFi UAP Firmware; UniFi UAP-AC Firmware; UniFi USW Firmware; UniFi USG Firmware.
High [CVE-2019-25652] UniFi Network Controller Improper Certificate Validation Leading to Credential Theft via MITM
UniFi Network Controller before version 5.10.22 and 5.11.x before 5.11.18 contains an improper certificate verification vulnerability that allows adjacent network attackers to conduct man-in-the-middle attacks by presenting a false SSL certificate during SMTP connections. Attackers can intercept SMTP traffic and obtain credentials by exploiting the insecure SSL host verification mechanism in the SMTP certificate validation process.
Critical [CVE-2023-24104] UniFi: Ubiquiti Networks UniFi Dream Machine Pro v7.2.95 allows attackers to bypass domain restrictions via crafted packets.
Ubiquiti Networks UniFi Dream Machine Pro v7.2.95 allows attackers to bypass domain restrictions via crafted packets.
