Echo: github.com/kumahq/kuma/v2: security update to 2.7.25

medium Tenable Cloud Security Plugin ID 459740

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Kuma is a modern Envoy-based service mesh that can run on every cloud across both Kubernetes and VMs.
Prior to 2.7.25, 2.9.15, 2.11.13, 2.12.10, and 2.13.5, the default kuma-cp config leaks the admin
bootstrap token and signing keys to any webpage the operator visits while the control plane is reachable
from their browser. CorsAllowedDomains: [".*"] reflects any Origin, and LocalhostIsAdmin: true promotes
requests from 127.0.0.1 to mesh-system:admin. A cross-origin fetch() from a malicious page returns the
admin JWT and signing material. This vulnerability is fixed in 2.7.25, 2.9.15, 2.11.13, 2.12.10, and
2.13.5. (CVE-2026-45021)

Solution
