Clauster: Non-loopback deployments can serve the dashboard unauthenticated when auth.enabled is unset

Summary A Clauster instance bound to a non-loopback address e.g. 0.0.0.0 or a LAN IP can serve the entire dashboard and its API without any authentication — even when the operator has configured a password — if auth.enabled is left at its default false. The operator believes the instance is...

CVE-2026-56675 9router: Reverse proxy locality collapse allows unauthenticated access to 9router /v1 APIs

9Router is an AI router & token saver. Prior to 0.5.2, 9router treats loopback requests as trusted and allows /v1/ access without an API key, so a same-host reverse proxy that forwards public traffic to the backend through 127.0.0.1 causes src/dashboardGuard.js to misclassify external requests as...

CVE-2026-56675

9router prior to version 0.5.2 validates loopback requests as trusted, allowing unauthenticated access to /v1/* endpoints when a reverse proxy on localhost (127.0.0.1) forwards traffic. A remote attacker could reach /v1 APIs (e.g., /v1/models) without an API key, potentially abusing configured up...
