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 shows no concrete attack behavior. The scanner's credential-transfer concern resolves to conditional Google IAP signing for requests to the operator-configured admin service, and agent context files are written only through the explicit export command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-14T08:16:52.731Z - **Finished:** 2026-10-14T08:17:44.697Z - **Download time:** 1022 ms - **Static scan time:** 92 ms - **AI review time:** 50851 ms - **Total time:** 51966 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 surface was identified. The reviewed export and IAP credential flows match their described operation and require configured or caller-invoked use. - **Trigger:** The file export runs when the caller supplies the export command; IAP signing activates only when its service-account setting is configured. - **Impact:** The inspected source shows no unconsented credential disclosure or malicious agent configuration change. - **Review source:** ai\_review - **Reviewed:** 2026-10-14T08:17:44.697Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Export fetches context from the configured admin service and writes files to the selected output directory. IAP mode sends a Google access token to Google's IAM signing API and uses a short-lived JWT for requests to the configured admin service. - **Rationale:** Source inspection shows no concrete attack behavior. The scanner's credential-transfer concern resolves to conditional Google IAP signing for requests to the operator-configured admin service, and agent context files are written only through the explicit export command. - **Files touched:** CLAUDE.md, .claude/skills/\/SKILL.md - **Network endpoints:** https://iamcredentials.googleapis.com/v1/projects/-/serviceAccounts/{serviceAccount}:signJwt ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package entrypoints are its main module and two binaries; its only lifecycle script is prepublishOnly, which runs the build., Export fetches context from the configured admin install and writes CLAUDE.md and skill files; the requested export location is part of that documented feature., The export runs only when the caller selects the export command, and the output directory is caller-selected or the current directory by default., IAP signing is disabled unless the service-account environment setting is present, and configuration requires an admin URL., When enabled, the operator's Google access token is sent to Google's IAM signing API; the resulting JWT audience is derived from the configured admin URL, and requests carry the Caelo token to that configured URL. - **Evidence against:** The scanner's external credential-transfer hint does not match the inspected flow: the access token goes to Google's IAM signing API for JWT creation, while Caelo requests target the configured admin URL. ## Affected versions and remediation This report applies to @caelo-cms/mcp-server@0.10.48. - Review the evidence and your use of @caelo-cms/mcp-server@0.10.48 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.
