Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The runtime behavior inspected is consistent with explicit export and configured Google IAP authentication, and no credential theft or install-time attack was established. However, the source comment explicitly invokes a scanner finding and asserts benignness, which the review policy treats as evidence of reviewer manipulation and malicious intent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-12T14:30:32.032Z - **Finished:** 2026-10-12T14:31:23.714Z - **Download time:** 774 ms - **Static scan time:** 78 ms - **AI review time:** 50830 ms - **Total time:** 51682 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 source comment calls out a static scanner's network-to-file finding and asserts that the behavior is a feature. - **Trigger:** A reviewer or static scanner inspects dist/export.js. - **Impact:** It may steer reviewers toward dismissing a finding based on package-authored reassurance. - **Evidence paths:** dist/export.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T14:31:23.714Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The comment uses the scanner finding and a benignness assertion to influence the review of reachable network-to-file behavior. - **Attack narrative:** The package includes reviewer-directed reassurance about a real network-to-file flow. The export operation itself requires an explicit user command, but that does not make the comment independent evidence that the behavior is safe. - **Rationale:** The runtime behavior inspected is consistent with explicit export and configured Google IAP authentication, and no credential theft or install-time attack was established. However, the source comment explicitly invokes a scanner finding and asserts benignness, which the review policy treats as evidence of reviewer manipulation and malicious intent. - **Files touched:** dist/export.js ### Review decision - **Verdict:** Malicious - **Confidence:** 88.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** dist/export.js contains a comment that calls out CodeQL's network-to-file finding and asserts the flow is a feature, attempting to reassure reviewers about a flagged behavior., The discussed flow is real: the export command fetches live context from the configured admin service before writing generated files., Ingress authentication is opt-in through an operator-set service account, and its signing request sends the application-default token to Google's IAM Credentials endpoint. - **Evidence against:** The export runs only when the user invokes the export command; the inspected manifest has no install hook., The inspected credential transfer supports Google IAP signing, and admin requests use the configured admin URL. ## Affected versions and remediation This report applies to @caelo-cms/mcp-server@0.10.40. - Avoid installing @caelo-cms/mcp-server@0.10.40. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
