RAX30: Authentication Bypass Using an Alternate Path or Channel
CVE-2026-11731 is a high-severity authentication bypass using an alternate path or channel vulnerability in RAX30 from NETGEAR, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited from the same local network by an unauthenticated attacker, without any action from a user. The record lists version v1.0.15.110 as the first without the flaw, so updating RAX30 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.27% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update RAX30 to v1.0.15.110 or a later version.
- Update RAX29 to v1.0.15.110 or a later version.
- Update RAX28 to v1.0.15.110 or a later version.
- Read the advisory on kb.netgear.com for workarounds and exact fixed builds.

The underlying weakness: Authentication Bypass Using an Alternate Path or Channel
The product requires authentication, but the product has an alternate path or channel that does not require authentication.
How developers prevent this class of flaw
- Funnel all access through a single choke point to simplify how users can access a resource. For every access, perform a check to determine if the user has permissions to access the resource.
