A command injection vulnerability in certain affected NETGEAR Nighthawk devices allows a network-adjacent attacker with the ability to intercept and modify local network traffic (attacker in the middle) to compromise the confidentiality and integrity of the affected device.
CVE-2026-11739
This medium-severity CVE scores 4.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 1.1%, top 38% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
