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 shows a conditional transfer of a saved service token to an unrestricted configured endpoint, which warrants a warning. The default recipient is Hum's service, and no evidence establishes that an unrelated recipient was selected, so blocking is not supported. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-14T19:11:56.697Z - **Finished:** 2026-10-14T19:14:04.151Z - **Download time:** 1283 ms - **Static scan time:** 800 ms - **AI review time:** 125371 ms - **Total time:** 127454 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:** The CLI can send a saved Hum bearer token with failure diagnostics to a configurable service URL. The default is Hum's service, but the source does not restrict a custom destination to that host. - **Trigger:** A user runs the CLI while a reportable install or core failure is pending, or a CLI startup fails. - **Impact:** If the selected URL is an unrelated host, that host can receive the saved Hum token and diagnostic metadata. The source does not establish that a custom URL is configured or that token exposure has occurred. - **Evidence paths:** dist/cli.mjs, bin/hum.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-10-14T19:14:04.151Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The report selects \`HUM\_AUTH\_URL\`, then the saved \`auth\_url\`, then \`https://hum.metaphi.ai\`, and sends the saved access token as a bearer credential without a destination allowlist. - **Rationale:** The source shows a conditional transfer of a saved service token to an unrestricted configured endpoint, which warrants a warning. The default recipient is Hum's service, and no evidence establishes that an unrelated recipient was selected, so blocking is not supported. - **Files touched:** HUM\_HOME/credentials.json, HUM\_HOME/health.json, HUM\_HOME/install-id - **Network endpoints:** https://hum.metaphi.ai, HUM\_AUTH\_URL, credentials.json auth\_url ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The npm executable loads \`dist/cli.mjs\` as its active command entrypoint., The CLI queues reports for recorded install failures, core failures, or startup errors, and calls the reporting path during CLI use., The report reads a saved access token and uses \`HUM\_AUTH\_URL\` or the saved \`auth\_url\` to select its destination, defaulting to \`https://hum.metaphi.ai\`., The report sends failure diagnostics and the saved token in an HTTP request with a bearer authorization header. - **Evidence against:** The default report destination is Hum's service, and the report is limited to queued install or startup failures. ## Affected versions and remediation This report applies to @metaphi-ai/hum@0.2.64. - Review the evidence and your use of @metaphi-ai/hum@0.2.64 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.
