Security Researcher Detected: You might have ended up here because your site vulnerability scanner found something interesting. Hi! I'm a security engineer and I'm having a good time interacting with the people and bots that are interested in information security.
You will hopefully find this site is well-secured and I'm not interested in being hacked. I'm interested in learning about how people try to hack me, though.
What is this endpoint?
api/v1/istio/config
Istio Service Mesh Configuration
What an attacker could do
Exposed Istio configuration reveals mesh topology, routing rules, and mTLS/authorization policies, letting an attacker map internal services and craft requests that bypass intended traffic and security policies.
How to defend it
Keep the Istio control plane (istiod) and its config APIs internal to the cluster, enforce RBAC on Istio CRDs, and require STRICT mutual TLS for mesh traffic.
