AI assistants operating in the project may ingest package-supplied workspace instructions without explicit user action. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.1.12 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Static source inspection confirms lifecycle-time creation of a package-supplied AGENTS.md in the consuming project. Under the firewall policy this is unconsented AI-agent control-surface mutation and should be blocked despite otherwise package-aligned server code. Product guard normalized a concrete AI-agent control hijack publish\_block to the blockable dangerous-capability shape. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-07-03T01:33:01.217Z - **Finished:** 2026-07-03T01:33:33.860Z - **Download time:** 761 ms - **Static scan time:** 41 ms - **AI review time:** 31841 ms - **Total time:** 32643 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:** The package mutates the consuming workspace during npm postinstall by dropping an AI-agent instruction file. This is an unconsented lifecycle write to an agent control surface, even though the copied instructions are mostly package-aligned. - **Trigger:** npm install of @mode-db/server@0.1.12 - **Impact:** AI assistants operating in the project may ingest package-supplied workspace instructions without explicit user action. - **Evidence paths:** package.json, scripts/install-modeldb-workspace.mjs, templates/modeldb/AGENTS.md, scripts/clear-modeldb-cache.mjs, dist/cli.js, dist/dual-track-app.js - **Review source:** ai\_review - **Reviewed:** 2026-07-03T01:33:33.860Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall copies package-supplied AGENTS.md into consumer workspace - **Attack narrative:** On install, npm runs the package postinstall script. The script resolves the consumer workspace from INIT\_CWD or process.cwd, creates a modeldb directory, and copies the package's AGENTS.md into that workspace if absent. That file is an AI assistant instruction surface, so the package can influence future agent behavior without the user invoking the CLI or opting into workspace instruction installation. - **Rationale:** Static source inspection confirms lifecycle-time creation of a package-supplied AGENTS.md in the consuming project. Under the firewall policy this is unconsented AI-agent control-surface mutation and should be blocked despite otherwise package-aligned server code. Product guard normalized a concrete AI-agent control hijack publish\_block to the blockable dangerous-capability shape. - **Files touched:** package.json, scripts/install-modeldb-workspace.mjs, templates/modeldb/AGENTS.md, ./modeldb/AGENTS.md, scripts/clear-modeldb-cache.mjs ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** package.json runs postinstall node ./scripts/install-modeldb-workspace.mjs, scripts/install-modeldb-workspace.mjs uses INIT\_CWD/process.cwd to target consumer project, postinstall creates ./modeldb and copies templates/modeldb/AGENTS.md into ./modeldb/AGENTS.md, templates/modeldb/AGENTS.md is AI assistant workspace guidance installed during lifecycle - **Evidence against:** Template content is ModeDB-specific guidance, not overt credential theft or reviewer manipulation, No install-time network access found, dist CLI/server network behavior is package-aligned HTTP/WebSocket server functionality, postuninstall only removes resolved ModelDB cache directory ## Affected versions and remediation This report applies to @mode-db/server@0.1.12. - Avoid installing @mode-db/server@0.1.12. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
