CVE-2026-0407 — Authentication bypass in NETGEAR WiFi Range Extenders via network adjacent attacks

An insufficient authentication vulnerability in NETGEAR WiFi range extenders allows a network adjacent attacker with WiFi authentication or a physical Ethernet port connection to bypass the authentication process and access the admin panel.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.2% (30-day exploitation probability)+2
  • Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (NETGEAR EX2800, Netgear Ex2800 Firmware, NETGEAR EX3110…).
  2. Apply the fixed version or the patch documented under Remediation.
  3. Search available logs for exploit probes matching the vulnerability class (authentication), errors and authentication anomalies.

What should defenders know first?

CVE-2026-0407 is "Authentication bypass in NETGEAR WiFi Range Extenders via network adjacent attacks", rated High. It affects EX2800 (NETGEAR); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 8.0 describes technical severity. EPSS 0.25% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
