Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 20 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 1.0.826 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The postinstall PATH change is ordinary package setup. The inspected credential flows target the configured product or provider APIs, and agent configuration actions require user approval; scanner signals did not establish a concrete attack surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-14T08:55:45.498Z - **Finished:** 2026-10-14T08:58:49.862Z - **Download time:** 1282 ms - **Static scan time:** 4406 ms - **AI review time:** 178675 ms - **Total time:** 184364 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:** No attack behavior was identified in the inspected source. The install helper adjusts PATH, while account and agent configuration changes follow browser approval or explicit user commands. - **Trigger:** npm install runs the PATH helper; login, provider setup, hook approval, and MCP setup are invoked interactively or through explicit commands. - **Impact:** No confirmed unrelated credential transfer or unconsented agent control change was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-14T08:58:49.862Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The helper makes an idempotent PATH change. Pairing and token renewal use the configured API, provider keys go through the local API, and project hooks and MCP tools have user approval steps. - **Rationale:** The postinstall PATH change is ordinary package setup. The inspected credential flows target the configured product or provider APIs, and agent configuration actions require user approval; scanner signals did not establish a concrete attack surface. ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** package.json runs a postinstall PATH helper; its implementation makes an idempotent shell PATH adjustment., Project hooks run only after approval, and the approval is made through the explicit hooks command., MCP servers are added through an explicit command; granting their tools automatic access requires an affirmative prompt., Browser pairing uses the package’s configured API and stores a worker key only after browser approval; token renewal sends credentials to the mode’s API endpoint., Provider keys are prompted for and saved through the local API, associated with the configured provider row., The reviewed MongoDB, proxy, and agent-stop code supports local setup, configured model requests, and stopping ended jobs; it does not establish attack behavior. ## Affected versions and remediation This report applies to @tiens.nguyen/gu-cli@1.0.826. - Review the evidence and your use of @tiens.nguyen/gu-cli@1.0.826 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.
