GHSA-86M2-FCXQ-5Q7C 9router: Unauthenticated `/v1` proxy access via `Host`-header spoofing → open AI relay + SSRF

Summary 9router's request guard decides a request is "local" and therefore exempt from API-key auth on the /v1 LLM proxy by reading the client-controlled Host header. Because 9router binds 0.0.0.0 by default and the CLI misleadingly prints "localhost", a remote, unauthenticated attacker who can...
