CVE-2026-77550 Aug 26, 10:33 CRITICAL PATCH Act Now

Authentication bypass in Ubiquiti UniFi OS lets a network-adjacent, unauthenticated attacker abuse improper neutralization of CRLF sequences (CWE-93) to gain access to affected consoles and gateways. It impacts a broad line of UniFi OS devices - Cloud Keys, Dream Machines/Routers, Network Video Recorders, Cloud Gateways, Enterprise Firewall/Fortress and NAS appliances, and the UniFi OS Server. Vendor-rated CVSS 10.0; no public exploit identified at time of analysis, and it is not listed in CISA KEV.

CVE-2026-77549 Aug 26, 10:30 CRITICAL PATCH Act Now

Authentication bypass in Ubiquiti UniFi OS lets a network-adjacent attacker circumvent login on affected devices by injecting CRLF sequences, granting full control over the appliance under certain conditions. It affects a broad range of UniFi OS platforms including Cloud Gateways, Dream Machines/Routers, Cloud Keys, and Enterprise NVR/NAS hardware. Reported by Ubiquiti with a CVSS of 9.0; there is no public exploit identified at time of analysis and it is not listed in CISA KEV, though the high scope-changing impact makes it a priority to patch.

CVE-2026-77545 Aug 26, 10:13 CRITICAL PATCH Act Now

Privilege escalation in Ubiquiti UniFi OS affects a broad range of gateway, NVR, storage, and Cloud Key appliances running the UniFi OS platform, where leftover Active Debug Code (CWE-489) lets an authenticated low-privilege actor with network access elevate their privileges on the device. The flaw is vendor-reported via Ubiquiti Security Advisory Bulletin 067 and carries a 9.0 CVSS driven by a security-scope change and full confidentiality, integrity, and availability impact. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the wide device footprint makes it a notable patch priority.

CVE-2026-77536 Aug 26, 09:35 CRITICAL PATCH Act Now

Privilege escalation in Ubiquiti UniFi OS lets a low-privileged actor with network access to an affected device elevate their rights to full administrative control, per Ubiquiti Security Advisory Bulletin 067 (CVE-2026-77536). The flaw stems from improper access control (CWE-284) and carries a near-maximum CVSS 9.9 due to a scope-changing impact across confidentiality, integrity, and availability. No public exploit identified at time of analysis, and it is not listed in CISA KEV.

CVE-2026-77534 Aug 26, 09:21 CRITICAL PATCH Act Now

Privilege escalation in Ubiquiti UniFi OS devices allows a network-adjacent attacker holding a low-privileged account to elevate to higher privileges on the affected device or instance due to an improper access control flaw. The issue spans Ubiquiti's core managed platforms - UniFi OS Server, Cloud Keys, Dream Machines/Routers, Cloud Gateways, NVR/Enterprise NVR, Enterprise NAS, and Enterprise Firewall/Fortress Gateway - and carries a critical CVSS 9.9 with a changed scope. No public exploit has been identified at time of analysis, but the low attack complexity and low privilege requirement make it high priority.

CVE-2026-54401 Jul 02, 14:49 HIGH PATCH This Week

Privilege escalation via Server-Side Request Forgery affects Ubiquiti UniFi OS devices and the UniFi OS Server across the Dream Machine, Dream Router, Cloud Gateway, Cloud Key, Enterprise Fortress/Firewall, and NVR/EVR product lines running versions below 5.1.19. A low-privileged user with network access can coerce the device into making attacker-controlled internal requests, leveraging the SSRF to reach privileged internal services and elevate to higher privileges within the appliance. No public exploit identified at time of analysis, EPSS risk is low (0.20%, 10th percentile), and the flaw is not listed in CISA KEV, but a vendor patch is available.

Command injection in Ubiquiti UniFi OS (all builds before 5.1.19) lets a low-privileged user on the same network run arbitrary operating-system commands on the underlying host device, giving full control of gateways, recorders, and Cloud Keys. The flaw stems from improper input validation (CWE-20) and carries high confidentiality, integrity, and availability impact (CVSS 8.8). There is no public exploit identified at time of analysis, and CISA's SSVC framework rates exploitation as none, but the technical impact is total and a vendor patch is already available.

Privilege escalation in Ubiquiti UniFi OS allows a low-privileged, network-adjacent user to chain a series of authenticated SQL injection flaws (CWE-89) to gain elevated privileges on affected UniFi OS instances and hardware. The issue affects UniFi OS Server and a broad range of Ubiquiti gateway, recorder, and Cloud Key appliances. There is no public exploit identified at time of analysis, and the flaw is not listed in CISA KEV, but the CVSS 8.8 rating and low attack complexity make it a meaningful escalation risk once an attacker has any authenticated foothold.

CVE-2026-54403 Jul 02, 14:49 HIGH PATCH This Week

Authentication bypass in Ubiquiti UniFi OS devices allows a network-adjacent attacker to abuse a path traversal flaw (CWE-22) to reach protected functionality without valid credentials, affecting a broad hardware line including Dream Machines/Routers/Wall, Cloud Gateways/Keys, Express 7, Enterprise Fortress Gateway, and the UniFi OS Server software. The CVSS 8.6 rating is driven by an unauthenticated, low-complexity network vector combined with a scope change (S:C), meaning the compromised authentication boundary exposes managed device data. No public exploit identified at time of analysis and it is not listed in CISA KEV, but the ubiquity of affected consoles makes this a high-priority patch.

CVE-2026-55110 Jul 02, 14:49 MEDIUM PATCH This Month

Cross-site session abuse in Ubiquiti UniFi OS lets a remote attacker who lures an authenticated operator to a malicious web page ride that user's active session to perform privileged actions on the device, stemming from a permissive CORS policy that trusts untrusted origins. The flaw affects UniFi OS Server and the console firmware running on Dream Machines, Dream Routers, Dream Wall, Cloud Gateways, Cloud Keys, Enterprise Fortress Gateway, Express 7, and Network/Enterprise Video Recorders. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; success hinges on social-engineering an already-logged-in admin (CVSS 7.5, UI:R, AC:H).
