The fix

We hold no Microsoft remediation data for CVE-2026-73461, which normally means it is not a Windows CVE. For non-Microsoft software the fix is the vendor's own updated release, and the affected versions are listed below.

What it is

On affected EOS platforms with AAA-based gRPC authorization enabled for OpenConfig, gRPC requests of an authenticated user to OpenConfig may use the wrong privilege level, resulting in an authorization using the wrong AAA method list. This does not impact non-gRPC OpenConfig requests such as NETCONF.
