Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 12 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.10.36 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. The source shows no install-time execution or package-controlled credential recipient. The flagged network and file operations are consistent with explicitly invoked export and opt-in IAP access to the operator-configured admin service. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-10T16:47:48.835Z - **Finished:** 2026-10-10T16:48:16.032Z - **Download time:** 777 ms - **Static scan time:** 63 ms - **AI review time:** 26357 ms - **Total time:** 27197 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 supports optional Google IAP access to the configured Caelo admin, while context export is an explicit command that writes fetched content into the chosen working directory. - **Trigger:** The operator invokes the export command, or configures CAELO\_IAP\_SERVICE\_ACCOUNT and makes an admin request on an IAP-protected install. - **Impact:** No confirmed credential theft or other attack surface was established in the inspected flows. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T16:48:16.032Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Export fetches context from the configured admin API and writes it locally; IAP mode sends a Google access token to Google IAM Credentials to sign a JWT whose audience is derived from the configured admin URL, then uses that JWT for admin requests. - **Rationale:** The source shows no install-time execution or package-controlled credential recipient. The flagged network and file operations are consistent with explicitly invoked export and opt-in IAP access to the operator-configured admin service. - **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:** The manifest exposes the server entrypoint and has only a prepublishOnly build hook, with no install-time hook., The export path fetches the operator’s Caelo context and writes it to files only when the user invokes the export command; skill slugs are checked before creating skill paths., IAP signing is opt-in through CAELO\_IAP\_SERVICE\_ACCOUNT, creates an audience from the configured admin URL, and sends the access token to Google IAM Credentials to sign a JWT for that audience., The signed JWT is then used as an authorization header for requests to the configured admin URL. ## Affected versions and remediation This report applies to @caelo-cms/mcp-server@0.10.36. - Review the evidence and your use of @caelo-cms/mcp-server@0.10.36 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.
