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 environment override is an explicit configuration choice, but the source does not restrict its destination before forwarding the Google bearer token. Treat this as conditional credential exposure and warn; the inspected source does not establish default disclosure or a separate attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-16T06:58:45.860Z - **Finished:** 2026-10-16T07:00:41.524Z - **Download time:** 780 ms - **Static scan time:** 2100 ms - **AI review time:** 112783 ms - **Total time:** 115664 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 configured provider endpoint can receive the user’s Google access token. This is conditional credential exposure through an explicit endpoint override. - **Trigger:** A provider request is transformed while OPENCODE\_AGY\_ENDPOINT points to a non-Google destination. - **Impact:** The configured recipient can receive the Google access token. The source does not establish that this happens with the default endpoint. - **Evidence paths:** dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-16T07:00:41.524Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The request transformation attaches a bearer token and sends the request to the configured endpoint; no destination restriction is shown in the inspected code. - **Rationale:** The environment override is an explicit configuration choice, but the source does not restrict its destination before forwarding the Google bearer token. Treat this as conditional credential exposure and warn; the inspected source does not establish default disclosure or a separate attack. - **Files touched:** dist/index.js - **Network endpoints:** https://daily-cloudcode-pa.googleapis.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package entrypoint loads the bundled runtime., The manifest lists no install lifecycle hook., The provider endpoint can be replaced through an environment variable; Google is the default., For matching requests, the runtime attaches the saved access token and constructs the request URL from that endpoint., Three runtime paths pass the access token into the request transformation. - **Evidence against:** Without an endpoint override, the configured provider endpoint is Google’s Code Assist service., The package is an OpenCode Google authentication plugin, and its network behavior is tied to provider requests. ## Affected versions and remediation This report applies to @anthonyhaussman/opencode-agy-auth@1.4.0. - Review the evidence and your use of @anthonyhaussman/opencode-agy-auth@1.4.0 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.
