Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 13 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 1.0.18 - **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The hook’s normal memory API credential flow targets Supermemory, but its automatic first-session authentication also sends the hostname and full working directory to the vendor’s auth endpoint. That undisclosed identifying data makes this suspicious telemetry rather than a credential theft finding. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-11-01T02:45:44.186Z - **Finished:** 2026-11-01T02:46:27.696Z - **Download time:** 506 ms - **Static scan time:** 719 ms - **AI review time:** 42284 ms - **Total time:** 43510 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:** Automatic authentication discloses identifying host and project path details to Supermemory. - **Trigger:** A Codex session starts while no Supermemory API key is configured. - **Impact:** The auth service receives the machine hostname and local project path, which may reveal a username or project name. - **Evidence paths:** dist/hooks/session-start.js - **Review source:** ai\_review - **Reviewed:** 2026-11-01T02:46:27.696Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook creates an authentication URL containing the machine hostname and current working directory, then opens it in a browser. - **Rationale:** The hook’s normal memory API credential flow targets Supermemory, but its automatic first-session authentication also sends the hostname and full working directory to the vendor’s auth endpoint. That undisclosed identifying data makes this suspicious telemetry rather than a credential theft finding. - **Files touched:** ~/.codex/supermemory/credentials.json - **Network endpoints:** https://console.supermemory.ai/auth/connect ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The session-start hook automatically starts authentication when no API key is configured., The auth query parameters include the machine hostname and full current working directory., The hook opens the auth URL at console.supermemory.ai, sending those parameters to the service. - **Evidence against:** package.json declares build, typecheck, and test scripts, but no install lifecycle script., Memory API requests use the configured Supermemory API base URL, with the service default when none is set. ## Affected versions and remediation This report applies to codex-supermemory@1.0.18. - Review the evidence and your use of codex-supermemory@1.0.18 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.
