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 bundle hard-codes a nonstandard Tailscale host as the sponsor relay for Solve transactions, creating an undisclosed dependency on that host during submissions. The reviewed code does not establish credential theft or justify a malicious verdict, so this warrants a warning rather than a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-30T10:32:57.560Z - **Finished:** 2026-10-30T10:34:15.887Z - **Download time:** 1026 ms - **Static scan time:** 658 ms - **AI review time:** 76641 ms - **Total time:** 78327 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:** A fixed, unofficial Tailscale hostname is used as the transaction sponsor for Solve submissions. - **Trigger:** The user runs \`tangle solve submit\`. - **Impact:** The relay is involved in sponsored transaction handling. Its role and relationship to the package publisher are not established by the reviewed source; no credential theft is confirmed. - **Evidence paths:** dist/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-30T10:34:15.887Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI pins Solve metadata to the hard-coded sponsor URL and routes its Tempo wallet client through that sponsor relay. - **Rationale:** The bundle hard-codes a nonstandard Tailscale host as the sponsor relay for Solve transactions, creating an undisclosed dependency on that host during submissions. The reviewed code does not establish credential theft or justify a malicious verdict, so this warrants a warning rather than a publish block. - **Network endpoints:** drew-gtr-pro.taild10bfc.ts.net ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The bundle hard-codes drew-gtr-pro.taild10bfc.ts.net as its Solve transaction sponsor., The wallet client routes Tempo transactions through the configured sponsor relay., The relay is used by the explicit \`tangle solve submit\` command., Solve credentials are restricted to the fixed Solve API endpoint. - **Evidence against:** The manifest declares no install, preinstall, or postinstall lifecycle script., Claude token capture is part of an explicit login flow and checks that the Sandbox API URL is credential-free HTTPS., The reviewed source does not show a private key or Solve API credential being sent to the sponsor host. ## Affected versions and remediation This report applies to @tangle-network/sandbox-cli@0.21.20. - Review the evidence and your use of @tangle-network/sandbox-cli@0.21.20 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.
