Overview ¶

Package safehttp provides an HTTP client hardened against SSRF, for fetching attacker-influenced URLs (CIMD documents, JWKS, MCP upstreams). It refuses to connect to loopback, private, link-local, or unspecified addresses — checked on the *resolved* IP and pinned for the dial, which defeats DNS-rebinding — allows only https, and bounds redirects, time, and response size.

Functions ¶

func Client ¶

func Client(allowLoopback bool) *http.Client

Client builds an SSRF-hardened http.Client. allowLoopback permits connections to loopback addresses (for tests / local dev only).

func GetJSON ¶

func GetJSON(ctx context.Context, client *http.Client, url string, v any, maxBytes int64) error

GetJSON fetches url with the hardened client and decodes the JSON body into v. Only https URLs are accepted, and the body is capped at maxBytes.
