With no GRID\_TOKEN, a reachable caller can pair it to an arbitrary master, which can supply payloads and commands for execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-07-30T12:40:13.945Z - **Finished:** 2026-07-30T12:40:46.136Z - **Download time:** 505 ms - **Static scan time:** 477 ms - **AI review time:** 31209 ms - **Total time:** 32191 ms ## Security analysis ### Published attack-surface review - **Summary:** Starting the CLI with no arguments launches a runner. With no GRID\_TOKEN, a reachable caller can pair it to an arbitrary master, which can supply payloads and commands for execution. - **Trigger:** User runs aegis-grid-runner; an unauthenticated network caller pairs the default-configured runner. - **Impact:** Remote code execution as the runner user, including inherited environment access and return of job artifacts/log summaries. - **Evidence paths:** package.json, bin.mjs, grid.mjs, README.md - **Review source:** ai\_review - **Reviewed:** 2026-07-30T12:40:46.136Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unauthenticated remote job pairing and shell execution - **Rationale:** This is a documented remote test-grid runner rather than covert malware, but its default unauthenticated pairing exposes a concrete remote-code-execution chain. No install-time execution or hard-coded exfiltration destination was found. - **Files touched:** bin.mjs, grid.mjs, .grid-agent/master.json, .grid-agent - **Network endpoints:** http://127.0.0.1:7717 ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** grid.mjs:4208 permits runner API access when GRID\_TOKEN is unset., grid.mjs:4237 accepts POST /api/master and persists the supplied master., grid.mjs:4562 runs npm install on master-supplied job payload., grid.mjs:4581 executes master-supplied meta.cmd via bash -lc with inherited env., grid.mjs:4627 uploads job artifacts and output summary to the paired master. - **Evidence against:** package.json has no preinstall/install/postinstall hooks., bin.mjs only defaults an explicit CLI invocation to runner start., README.md documents the grid, pairing, and remote job-execution design., No hard-coded third-party exfiltration endpoint or stealth payload was found. ## Public findings ### 1.
