Huginn closes a JqAgent leak of server secrets and outbound proxy bypasses.
Huginn has shipped near-weekly releases since August, mostly security fixes. v2026.11.09 starts jq with an empty environment so JqAgent filters can no longer read server environment variables, and enforces OUTBOUND_PROXY on HTTP paths that bypassed it, including JiraAgent and WeiboPublishAgent. Operators who enabled jq with untrusted users are told to rotate APP_SECRET_TOKEN and other credentials. It follows the 5 November XSS fixes and the Rails 8.1.4.1 upgrade.
Ably's AI Transport hits 1.0 and plugs straight into Vercel's useChat with resumable streams.
Ably is repositioning its realtime pub/sub network as the transport layer for AI agent output. AI Transport JS 1.0 runs on ordinary Pub/Sub channels and ships adaptors for the Vercel AI SDK, OpenAI Responses API and AG-UI, plus a useChat transport that resumes a stream after a reload. It lands a week after the switch to monthly-active-user pricing and breaking SDK majors that split every client into device and server packages.

An outside researcher's reports are driving a steady security audit of Huginn's agents, one agent type at a time. Each release narrows what a user-built agent can reach on the host.
More agent-level hardening is likely, especially for agents that run shell tools or make network calls, given the pattern of the last three releases. Whether this leads to a formal sandbox for user agents is not visible.

The November releases fit one plan: split clients so MAU billing can count end users, then make the AI layer a thin adaptor on top of the same channels used for chat, presence and LiveObjects. Server-side additions in Java and JS (HTTP LiveObjects, channel pools, a Temporal plugin) point at agent backends as the intended publisher.
Expect more agent framework adaptors and server SDKs reaching AI Transport parity, with Chat and LiveObjects examples built around agents joining human conversations.
