Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The source allows an environment-provided API origin and forwards GRUM\_TOKEN to it without verifying the token's intended recipient. This creates a conditional credential-exposure risk, while the inspected agent setup is explicitly prompted and does not establish a separate attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-16T03:10:56.552Z - **Finished:** 2026-10-16T03:12:55.140Z - **Download time:** 1546 ms - **Static scan time:** 1603 ms - **AI review time:** 115438 ms - **Total time:** 118588 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** When GRUM\_TOKEN is set, authenticated CLI requests can send that token to the origin selected through GRUM\_API\_ORIGIN. The source accepts any HTTP(S) origin and does not bind the environment token to it. - **Trigger:** Run a CLI operation that makes an authenticated project request while GRUM\_TOKEN is set and GRUM\_API\_ORIGIN points to a different service. - **Impact:** The selected recipient can receive the token. This is conditional on runtime environment configuration; the source does not establish covert collection. - **Evidence paths:** grum.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-16T03:12:55.140Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The token loader pairs GRUM\_TOKEN with the selected origin, and the request helper sends it in a bearer authorization header. - **Rationale:** The source allows an environment-provided API origin and forwards GRUM\_TOKEN to it without verifying the token's intended recipient. This creates a conditional credential-exposure risk, while the inspected agent setup is explicitly prompted and does not establish a separate attack. - **Network endpoints:** https://app.grum.so, GRUM\_API\_ORIGIN-selected HTTP(S) origin ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The indicated agent location is a local Grum Cursor rule path, and interactive setup asks before installing agent configuration., The API origin can be set to any HTTP(S) origin; the built-in default is Grum's app service., A GRUM\_TOKEN environment value is paired with the selected origin without checking that the token belongs to it; saved credential files are origin-bound., Authenticated project lookups pass that token to a request that sends it as a bearer credential to the selected origin., The package exposes grum.mjs as its CLI entrypoint. - **Evidence against:** The saved-session path accepts credentials only when their stored API origin matches the configured origin. The exposure therefore depends on the separate GRUM\_TOKEN environment path and a caller-selected origin. ## Affected versions and remediation This report applies to @grum-os/cli@0.3.38. - Review the evidence and your use of @grum-os/cli@0.3.38 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
