Security

• Hardened SSRF IP-literal matching for IPv6-mapped forms. The private/loopback/
  link-local guard (isPrivateIP) now parses addresses structurally via ipaddr.js
  instead of regex-matching them, so IPv4-mapped IPv6 addresses are blocked in every
  canonical spelling — including the hex-group form the WHATWG URL parser produces
  (e.g. [::ffff:127.0.0.1] → ::ffff:7f00:1), which the previous dotted-decimal-only
  match let through. Applies to all four guard entry points (checkSSRF,
  checkSSRFSync, the connect-time guardedLookup rebinding guard, and
  checkJitHttpProvisionUrl), closing the bypass for outbound hook URLs and HTTP JIT
  provisioning targets. Public unicast addresses (including IPv4-mapped public
  addresses) are unaffected. Regression tests added.

Fixed

• exec_with_secrets profile description now states the real guarantee. The
  restricted profile's MCP tool description claimed it "limits PATH and inheritable
  env vars"; in fact it denies a fixed list of network-tool binaries, strips proxy env
  vars, and caps runtime — it does not restrict PATH, and interpreters invoked
  directly (python, node, …) can still perform network I/O and read the injected
  secrets. The description now says so and points to OS-level isolation for untrusted
  commands. (No behavior change; a hardened restricted profile follows in 0.14.0.)

Dependencies

• ipaddr.js promoted to a direct dependency (^1.9.1; already present transitively).
  It backs the SSRF address parsing above. The published package's runtime dependency
  set is otherwise unchanged.
