Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 0.26.22 - **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. LPM treats this as warn-only first-party agent extension lifecycle risk. Explicit plugin installation adds gmax capabilities and daemon hooks to supported AI coding clients. No unconsented lifecycle mutation or concrete malicious chain was established. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-08-26T01:05:31.966Z - **Finished:** 2026-08-26T01:06:39.872Z - **Download time:** 1011 ms - **Static scan time:** 5419 ms - **AI review time:** 61475 ms - **Total time:** 67906 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 adds gmax capabilities and daemon hooks to supported AI coding clients. No unconsented lifecycle mutation or concrete malicious chain was established. - **Trigger:** User runs gmax plugin add/update or a legacy install command. - **Impact:** Installed agents can invoke gmax and may start its project-indexing daemon. - **Evidence paths:** package.json, scripts/postinstall.js, dist/index.js, dist/commands/plugin.js, dist/commands/codex.js, dist/commands/opencode.js - **Review source:** ai\_review - **Reviewed:** 2026-08-26T01:06:39.872Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Writes first-party AI-agent integration shims and registers gmax MCP. - **Rationale:** The package has explicit user-command AI-agent configuration mutation, warranting a warning under the firewall policy. Its postinstall hook is informational only, so the evidence does not support a malicious/block verdict. - **Files touched:** ~/.codex/AGENTS.md, ~/.config/opencode/tool/gmax.ts, ~/.config/opencode/plugins/gmax.ts ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Explicit plugin commands install integrations into detected AI coding clients., Codex integration registers an MCP command and writes a gmax block to ~/.codex/AGENTS.md., OpenCode integration writes executable tool/daemon plugin shims into its user config. - **Evidence against:** postinstall only prints instructions and does not mutate agent configuration., Integration writes require an explicit gmax plugin/install command; no covert install-time control-surface mutation found., No credential harvesting or exfiltration path was found in inspected sources. ## Affected versions and remediation This report applies to grepmax@0.26.22. - Review the evidence and your use of grepmax@0.26.22 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.
