Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 0.26.28 - **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. Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-08T17:32:58.320Z - **Finished:** 2026-09-08T17:34:19.282Z - **Download time:** 251 ms - **Static scan time:** 6619 ms - **AI review time:** 74091 ms - **Total time:** 80962 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:** Explicit plugin installation modifies AI-agent configuration and can install session hooks. The install-time hook itself only displays a message, so it does not trigger this behavior. - **Trigger:** The user runs gmax plugin add or gmax plugin update, including the interactive setup choice. - **Impact:** Installed agent sessions may invoke gmax and start or stop its daemon; this is a user-requested capability change rather than silent installation-time persistence. - **Evidence paths:** dist/commands/plugin.js, dist/commands/codex.js, dist/commands/droid.js - **Review source:** ai\_review - **Reviewed:** 2026-09-08T17:34:19.282Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Explicit AI-agent integration installs MCP settings, skills, and background-daemon hooks. - **Rationale:** This is an explicit-user-command agent integration with durable configuration and background hooks, which warrants a warning under the policy. Source inspection does not establish malicious install-time behavior or data theft. - **Files touched:** ~/.codex/AGENTS.md, ~/.factory/settings.json, ~/.factory/hooks/gmax/gmax\_start.js, ~/.factory/hooks/gmax/gmax\_stop.js, ~/.factory/skills/gmax/SKILL.md, ~/.config/opencode/tool/gmax.ts, ~/.config/opencode/plugins/gmax.ts ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest runs a postinstall hook, requiring lifecycle inspection., Explicit plugin commands install integrations for detected AI coding clients., The Codex installer registers an MCP command and writes instructions to the user's Codex configuration., The Factory Droid installer enables hooks that start and stop a background gmax daemon. - **Evidence against:** The postinstall script only prints guidance and does not modify configuration or execute a child process., Agent configuration changes occur only through explicit plugin-install commands., No credential harvesting, secret exfiltration, remote payload execution, or self-dependency was found., The only inspected external download is a Hugging Face model asset used by setup/runtime code. ## Affected versions and remediation This report applies to grepmax@0.26.28. - Review the evidence and your use of grepmax@0.26.28 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.
