Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection found no lifecycle install hook or concrete attack behavior. The flagged network, environment, and subprocess operations support the plugin's authentication, provider, and storage behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-10-27T19:10:49.643Z - **Finished:** 2026-10-27T19:12:53.957Z - **Download time:** 775 ms - **Static scan time:** 2154 ms - **AI review time:** 121384 ms - **Total time:** 124314 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:** No attack was identified in the inspected source. The package implements Google authentication for an OpenCode plugin and includes expected provider and storage helpers. - **Trigger:** OpenCode loads the plugin and invokes its authentication or provider functions. - **Impact:** The inspected behavior supports authentication and provider storage; no unrelated credential recipient, unrequested account action, or harmful install behavior was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-27T19:12:53.957Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inspected authentication flow uses Google OAuth and PKCE, refreshes tokens through Google's OAuth endpoint, and can open the authorization URL in a browser. The AWS helper is used by the dependency's DynamoDB storage path. - **Rationale:** Source inspection found no lifecycle install hook or concrete attack behavior. The flagged network, environment, and subprocess operations support the plugin's authentication, provider, and storage behavior. - **Files touched:** dist/index.js - **Network endpoints:** accounts.google.com, oauth2.googleapis.com, dynamodb.${c.region}.amazonaws.com ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package exports its built plugin and lists development, packaging, and prepack scripts; no install lifecycle script is present., The authentication flow creates a PKCE challenge and directs authorization to Google; its browser-opening path receives the generated authorization URL., Refresh requests send the stored refresh token to Google's OAuth token endpoint., The inspected AWS helper obtains credentials from AWS environment variables or the container metadata URI; its DynamoDB caller uses the AWS client with a caller-configurable endpoint or the regional AWS endpoint., The inspected dependencies expose provider, authentication, and plugin modules through their package entrypoints., The OpenAuth dependency's inspected issuer source contains a token route that accepts form data. - **Evidence against:** The bundle uses a subprocess to open the authorization URL and reads environment variables for configuration; these inspected uses align with browser-based authentication and provider setup., The package and dependencies use network requests, including Google OAuth and AWS DynamoDB requests; the inspected recipients and data flow align with those functions. ## Affected versions and remediation This report applies to @anthonyhaussman/opencode-agy-auth@1.4.8. - Review the evidence and your use of @anthonyhaussman/opencode-agy-auth@1.4.8 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.
