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 code is not malicious under the install-control policy because there is no automatic npm lifecycle mutation and setup is explicitly user-invoked. It should be warned because it installs persistent Codex hooks that can upload conversation content and references a different runtime package release. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-08-28T18:21:38.671Z - **Finished:** 2026-08-28T18:22:17.696Z - **Download time:** 504 ms - **Static scan time:** 430 ms - **AI review time:** 38090 ms - **Total time:** 39025 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 user-run initializer changes Codex configuration and installs automatic hooks. With a configured MemoryRouter API key, those hooks transmit captured Codex prompt and response content to the MemoryRouter service. - **Trigger:** The user runs memoryrouter-codex init and later uses Codex with the installed hooks and an API key. - **Impact:** Codex conversation content may be retained locally and uploaded to the configured MemoryRouter vault; the installer also creates a runtime npx dependency on an older release. - **Evidence paths:** package.json, bin/cli.cjs, lib/installer.cjs, lib/managed.cjs, lib/hooks.cjs, runtime/hook.cjs, runtime/memory.cjs, runtime/api.cjs - **Review source:** ai\_review - **Reviewed:** 2026-08-28T18:22:17.696Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Explicit Codex extension setup with lifecycle memory capture and API upload. - **Rationale:** The code is not malicious under the install-control policy because there is no automatic npm lifecycle mutation and setup is explicitly user-invoked. It should be warned because it installs persistent Codex hooks that can upload conversation content and references a different runtime package release. - **Files touched:** ~/.codex/config.toml, ~/.codex/hooks.json, ~/.codex/AGENTS.md, ~/.codex/memoryrouter/runtime/, \/.codex/config.toml, \/.codex/hooks.json, \/AGENTS.md, \/.codex/memoryrouter/runtime/, ~/.memoryrouter/codex/config.json - **Network endpoints:** https://api.memoryrouter.ai, https://mcp.memoryrouter.ai/mcp ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The explicit init command installs an MCP configuration, hooks, and an AGENTS.md block into user or project Codex surfaces., Installed hooks run on prompt, stop, compaction, and session events., The hooks save prompts and assistant responses, then send scoped memory content to the package API when an API key is configured., Project-scope hook configuration invokes a different package release through npx at runtime. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Configuration mutation requires the user to run the init command., The hook exits without capture or network use when no API key is available., No obfuscation, credential harvesting beyond the configured API key, arbitrary shell execution, or unrelated endpoint was found. ## Affected versions and remediation This report applies to memoryrouter-codex@1.3.0. - Review the evidence and your use of memoryrouter-codex@1.3.0 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.
