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. Saved EchoMem tokens are sent to environment-configurable endpoints without a host allowlist, which creates conditional credential exposure. The default endpoints are package-aligned and the override appears intended for alternate EchoMem services, so this warrants a warning rather than a malicious verdict. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-17T01:43:00.293Z - **Finished:** 2026-10-17T01:46:31.638Z - **Download time:** 1020 ms - **Static scan time:** 1919 ms - **AI review time:** 208405 ms - **Total time:** 211345 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 configured API or pricing endpoint can receive saved EchoMem bearer tokens. The default destinations are EchoMem services; the exposure arises when an operator sets an alternate endpoint. - **Trigger:** A user runs onboarding, unlock, status, migration, a connected MCP operation, HUD action, usage sync, or a configured session hook while an alternate endpoint is set. - **Impact:** The configured recipient can receive an existing EchoMem account token. The inspected source does not establish actual misuse or a package-selected unrelated default recipient. - **Evidence paths:** dist/setup.js, dist/index.js, dist/migrate.js, dist/codex-sync.js, dist/hud/diagnostics.js, dist/hud/server.js, dist/source-session-hook.js - **Review source:** ai\_review - **Reviewed:** 2026-10-17T01:46:31.638Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Runtime clients read saved tokens and attach them as bearer credentials to requests using ECHO\_API\_BASE\_URL or ECHO\_PRICING\_URL. The source does not bind those credentials to an allowed host. - **Rationale:** Saved EchoMem tokens are sent to environment-configurable endpoints without a host allowlist, which creates conditional credential exposure. The default endpoints are package-aligned and the override appears intended for alternate EchoMem services, so this warrants a warning rather than a malicious verdict. - **Files touched:** dist/setup.js, dist/index.js, dist/migrate.js, dist/codex-sync.js, dist/hud/diagnostics.js, dist/hud/server.js, dist/source-session-hook.js - **Network endpoints:** https://echo-mem-chrome.vercel.app, https://echoknows.com/account ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The API and pricing endpoints can be changed through environment variables, and authenticated clients attach a bearer token to requests at those bases., Onboarding, unlock, status, migration, MCP, HUD, diagnostics, usage-sync, and session-hook paths reuse a stored token in requests to the configurable API base., Billing requests also send a bearer token to the configurable pricing endpoint., The agent-integration locations show local session discovery, index reading, and profile-scoped hook setup; they do not establish broad agent-control mutation., The source describes local or older EchoMem API use for the API override, while the default endpoints are EchoMem services. - **Evidence against:** The potential exposure depends on an operator-configured endpoint; the inspected defaults point to EchoMem services., The package manifest has no install-time lifecycle hook, so the credential behavior is reached through runtime commands and requests. ## Affected versions and remediation This report applies to @echomem/mcp@1.4.62. - Review the evidence and your use of @echomem/mcp@1.4.62 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.
