Description

Summary

ACP-only provenance fields in chat.send were gated by self-declared client metadata from the WebSocket handshake rather than verified authorization state.

Impact

A normal authenticated operator client could spoof ACP identity labels and inject reserved provenance fields intended only for the ACP bridge.

Affected Component

src/gateway/server-methods/chat.ts, src/gateway/server/ws-connection/message-handler.ts

Fixed Versions

  • Affected: <= 2026.3.24
  • Patched: >= 2026.3.28
  • Latest stable 2026.3.28 contains the fix.

Fix

Fixed by commit 4b9542716c (Gateway: require verified scope for chat provenance).
