* fix(security): block plaintext WebSocket connections to non-loopback addresses
Addresses CWE-319 (Cleartext Transmission of Sensitive Information).
Previously, ws:// connections to remote hosts were allowed, exposing
both credentials and chat data to network interception. This change
blocks ALL plaintext ws:// connections to non-loopback addresses,
regardless of whether explicit credentials are configured (device
tokens may be loaded dynamically).
Security policy:
- wss:// allowed to any host
- ws:// allowed only to loopback (127.x.x.x, localhost, ::1)
- ws:// to LAN/tailnet/remote hosts now requires TLS
Changes:
- Add isSecureWebSocketUrl() validation in net.ts
- Block insecure connections in GatewayClient.start()
- Block insecure URLs in buildGatewayConnectionDetails()
- Handle malformed URLs gracefully without crashing
- Update tests to use wss:// for non-loopback URLs
Fixes#12519
* fix(test): update gateway-chat mock to preserve net.js exports
Use importOriginal to spread actual module exports and mock only
the functions needed for testing. This ensures isSecureWebSocketUrl
and other exports remain available to the code under test.
* fix(discord): defer component interactions to prevent timeout
Discord requires interaction responses within 3 seconds. Button clicks
were routed through the LLM pipeline before responding, exceeding this
window and showing 'This interaction failed' to users.
Now immediately defers the interaction, then processes the agent
response asynchronously.
Fixes#16262
* fix: harden deferred interaction replies and silent chat finals (#16287) (thanks @robbyczgw-cla)

* Gateway: require explicit auth for url overrides
* Gateway: scope credential blocking to non-local URLs only
Address review feedback: the previous fix blocked credential fallback for
ALL URL overrides, which was overly strict and could break workflows that
use --url to switch between loopback/tailnet without passing credentials.
Now credential fallback is only blocked for non-local URLs (public IPs,
external hostnames). Local addresses (127.0.0.1, localhost, private IPs
like 192.168.x.x, 10.x.x.x, tailnet 100.x.x.x) still get credential
fallback as before.
This maintains the security fix (preventing credential exfiltration to
attacker-controlled URLs) while preserving backward compatibility for
legitimate local URL overrides.
