Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The inspected flagged code describes an operator-configured Google IAP authentication flow, and the package manifest shows no install hook. The required clean citation set exceeds the 256-citation limit, so the result is manual review rather than a clean verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 76.0% - **Started:** 2026-10-20T13:41:40.484Z - **Finished:** 2026-10-20T13:42:33.961Z - **Download time:** 1020 ms - **Static scan time:** 145 ms - **AI review time:** 52311 ms - **Total time:** 53477 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 concrete attack was established in the inspected authentication flow. Full clean classification cannot be supported within the required citation limit. - **Trigger:** The IAP helper runs when an operator configures the service account and a request needs IAP authorization. - **Impact:** The inspected flow appears consistent with authenticated access to the operator’s Caelo admin, but the required clean-source citation coverage is incomplete. - **Review source:** ai\_review - **Reviewed:** 2026-10-20T13:42:33.961Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It asks Google IAM to sign a JWT for the configured service account, then sends that JWT with requests to the configured admin URL. - **Rationale:** The inspected flagged code describes an operator-configured Google IAP authentication flow, and the package manifest shows no install hook. The required clean citation set exceeds the 256-citation limit, so the result is manual review rather than a clean verdict. - **Network endpoints:** iamcredentials.googleapis.com ### Review decision - **Verdict:** Manual Review - **Confidence:** 76.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Low - **AI review observations:** The manifest points to CLI entrypoints and has no install lifecycle hook; \`prepublishOnly\` only builds the package., The flagged authentication code activates only when an operator configures \`CAELO\_IAP\_SERVICE\_ACCOUNT\` and obtains a signing token from Google IAM., The IAP signing request uses Google’s IAM Credentials endpoint, while normal API requests go to the configured Caelo admin URL., The required clean-review citation set exceeds the schema’s 256-citation limit. ## Affected versions and remediation This report applies to @caelo-cms/mcp-server@0.10.57. - Review the evidence and your use of @caelo-cms/mcp-server@0.10.57 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.
