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. 23 low-signal pattern(s) reviewed. - **Verdict:** Manual Review - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Under Review - **Threat category:** Unknown - **Selected version:** 1.12.3 - **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: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The inspected credential-related and agent-setup paths were constrained or consent-gated, and no package install hook was listed. Manual review is warranted because the declared playwright-core dependency remained unresolved in the supplied source snapshot. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 83.0% - **Started:** 2026-10-20T17:03:51.688Z - **Finished:** 2026-10-20T17:05:29.813Z - **Download time:** 1808 ms - **Static scan time:** 1964 ms - **AI review time:** 94351 ms - **Total time:** 98125 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 identified in the inspected package source. Assessment remains incomplete because a declared dependency's source was unavailable for inspection. - **Trigger:** Dependency installation or use may activate behavior in the unresolved dependency. - **Impact:** The dependency's install and runtime behavior cannot be verified from this snapshot. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-10-20T17:05:29.813Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package declares playwright-core 1.52.0, but the supplied snapshot did not include inspectable source for it. - **Rationale:** The inspected credential-related and agent-setup paths were constrained or consent-gated, and no package install hook was listed. Manual review is warranted because the declared playwright-core dependency remained unresolved in the supplied source snapshot. - **Files touched:** package.json ### Review decision - **Verdict:** Manual Review - **Confidence:** 83.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json declares playwright-core 1.52.0, but its prepared source could not be inspected in this snapshot, leaving its install behavior unresolved., The reviewed setup code gates project agent integration on explicit consent and checks project-local editor configuration., The mobile publish path runs a deploy command only when one is supplied by a command argument or project configuration., The server restricts signed-image reads to the configured backend origin and storage path, with redirects disabled. - **Evidence against:** The manifest lists ordinary start and maintenance scripts, with no npm install lifecycle hook., The flagged shell execution is conditional on a supplied deploy command; the inspected runtime fetch is origin and path constrained. ## Affected versions and remediation This report applies to pincushion-mcp@1.12.3. - Review the evidence and your use of pincushion-mcp@1.12.3 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.
