+### [CVE-2026-33186](https://nvd.nist.gov/vuln/detail/CVE-2026-33186)
+- **Author:** @lucasmrod
+- **Status:** `not_affected`
+- **Status notes:** There are no path-based authorization interceptors. The only interceptors are grpc_recovery (panic handlers). CVE-2026-33186 specifically requires path-based authz rules (like grpc/authz RBAC policies) that compare against info.FullMethod — Fleet doesn't use any.
