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. Inspected source does not support the scanner's exfiltration claim: the Google access token is sent to Google's IAM Credentials signing endpoint, and the resulting JWT audience is derived from the configured admin URL. Package installation has no install-time behavior beyond a prepublish-only build, while export requires an explicit command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-11T19:10:17.740Z - **Finished:** 2026-10-11T19:10:41.727Z - **Download time:** 1016 ms - **Static scan time:** 62 ms - **AI review time:** 22908 ms - **Total time:** 23987 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. The flagged credential flow is conditional IAP authentication to Google's signing service, with the resulting JWT intended for the configured admin install. - **Trigger:** IAP signing activates only when CAELO\_IAP\_SERVICE\_ACCOUNT is configured; export requires an explicit export command. - **Impact:** These flows support configured authentication and user-requested export; inspected source does not establish credential theft or an active attack. - **Review source:** ai\_review - **Reviewed:** 2026-10-11T19:10:41.727Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The client requests a signed JWT from Google IAM Credentials for the configured service account and admin URL. Export fetches context from that admin URL and writes generated files to the chosen output directory. - **Rationale:** Inspected source does not support the scanner's exfiltration claim: the Google access token is sent to Google's IAM Credentials signing endpoint, and the resulting JWT audience is derived from the configured admin URL. Package installation has no install-time behavior beyond a prepublish-only build, while export requires an explicit command. - **Files touched:** CLAUDE.md, .claude/skills/\/SKILL.md - **Network endpoints:** https://iamcredentials.googleapis.com ### Review decision - **Verdict:** Clean - **Confidence:** 96.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json has no install lifecycle hook; prepublishOnly only runs the TypeScript build., IAP signing is opt-in through CAELO\_IAP\_SERVICE\_ACCOUNT and requires the configured Caelo admin URL., The signing request sends the Google access token to Google's IAM Credentials endpoint and scopes the JWT audience to the admin URL., The export behavior runs only when the user invokes the export command; it fetches admin context and writes files under the selected output directory., Admin API requests target the configured admin URL and carry the Caelo token in its request header. ## Affected versions and remediation This report applies to @caelo-cms/mcp-server@0.10.34. - Review the evidence and your use of @caelo-cms/mcp-server@0.10.34 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.
