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 runtime routes Solve submission requests through a pinned custom sponsor relay whose ownership is unresolved. The inspected path does not establish credential theft or a concrete attack, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 76.0% - **Started:** 2026-10-25T03:54:41.769Z - **Finished:** 2026-10-25T03:55:32.469Z - **Download time:** 3323 ms - **Static scan time:** 641 ms - **AI review time:** 46735 ms - **Total time:** 50700 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 Solve CLI pins transaction submission to a custom sponsor relay whose relationship to the package is not established by inspected source. This leaves a limited, unresolved risk around transaction request disclosure to that relay; no credential exfiltration or other attack was confirmed. - **Trigger:** A user invokes a Solve submission that sends a signed transaction. - **Impact:** The relay receives Solve transaction requests; source inspection did not establish that API credentials are included or that the relay alters transactions. - **Evidence paths:** dist/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-25T03:55:32.469Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The runtime creates a wallet transport using the pinned sponsor relay URL. - **Rationale:** The runtime routes Solve submission requests through a pinned custom sponsor relay whose ownership is unresolved. The inspected path does not establish credential theft or a concrete attack, so this warrants a warning rather than a block. - **Files touched:** dist/index.mjs - **Network endpoints:** https://drew-gtr-pro.taild10bfc.ts.net/solve-sponsor, https://rpc.moderato.tempo.xyz ### Review decision - **Verdict:** Suspicious - **Confidence:** 76.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package manifest exposes a CLI that imports the bundled runtime and declares no install lifecycle hook., The bundled runtime pins Solve submissions to a custom sponsor relay on drew-gtr-pro.taild10bfc.ts.net., Solve submissions use the configured sponsor URL as the wallet transport for signed transactions., The Solve API key is read from an environment variable or saved profile; the inspected transaction relay path does not show that key being sent. - **Evidence against:** The relay is used for Solve submission transactions, and the reviewed source does not establish credential theft or another concrete attack. ## Affected versions and remediation This report applies to @tangle-network/sandbox-cli@0.20.39. - Review the evidence and your use of @tangle-network/sandbox-cli@0.20.39 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.
