            "summary": "@grackle-ai/powerline Runs Without Authentication by Default\n### Impact\n\nWhen `--token` is not provided and `GRACKLE_POWERLINE_TOKEN` is not set, the PowerLine gRPC server runs with **zero authentication**. A warning is logged (`\"NO AUTH (development only)\"`) but nothing prevents deployment in this state. Any client that can reach the PowerLine port can spawn agent sessions, access credential tokens, and execute code.\n\nThe default binding is `127.0.0.1` (loopback only), which limits exposure to the local machine. However, if PowerLine is accidentally exposed on a network (e.g., in a container or via port forwarding), the impact is critical.\n\n**Affected code:**\n- `packages/powerline/src/index.ts:46` — token defaults to empty string\n- `packages/powerline/src/index.ts:63-76` — auth interceptor is only added when token is truthy\n\n### Patches\n\n0.70.1\n\n**Fix:** Require an explicit `--no-auth` flag to run without authentication, rather than defaulting to no auth when the token is empty. Throw an error if starting without a token and without `--no-auth`.\n\n### Workarounds\n\nAlways provide `--token` or set `GRACKLE_POWERLINE_TOKEN` when starting PowerLine. The Grackle server does this automatically when managing PowerLine lifecycle.\n\n### Resources\n\n- CWE-306: Missing Authentication for Critical Function\n- File: `packages/powerline/src/index.ts`",
