A package install can add a broadly privileged AI-agent mode to a foreign global control surface without an explicit setup command. - **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:** 1.18.37 - **Selected version is latest:** Yes - **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. LPM flags this version as an AI-agent control-surface risk. Installation automatically modifies the global OpenCode agent and command configuration. One bundled agent enables unrestricted autonomous actions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-28T21:22:49.360Z - **Finished:** 2026-09-28T21:25:21.302Z - **Download time:** 260 ms - **Static scan time:** 28 ms - **AI review time:** 151653 ms - **Total time:** 151942 ms The recorded confidence comes from the underlying analysis.

One bundled agent enables unrestricted autonomous actions. - **Trigger:** npm installation runs the postinstall lifecycle script. - **Impact:** A package install can add a broadly privileged AI-agent mode to a foreign global control surface without an explicit setup command. - **Evidence paths:** package.json, postinstall.mjs, defaults/agent/auto.md - **Review source:** ai\_review - **Reviewed:** 2026-09-28T21:25:21.302Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script creates missing global configuration paths and copies bundled agent and command files there; the copied auto agent allows every permission. - **Attack narrative:** The package invokes a postinstall script automatically. That script populates the user's global OpenCode configuration with bundled agents and commands when files are absent. Its auto agent is configured to allow all permissions, including edits, shell activity, and external directories. This is an unconsented install-time modification of a broad AI-agent control surface. - **Rationale:** The automatic lifecycle hook writes an unrestricted agent configuration outside the package into a global AI-agent configuration directory. Existing-file preservation and an opt-out do not establish consent for this default mutation. - **Files touched:** package.json, postinstall.mjs, defaults/agent/auto.md ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json automatically runs postinstall.mjs during installation., The postinstall script copies bundled agent and command files into the user's global OpenCode configuration., The installed auto agent grants all permissions and states that edits, shell access, and external directories are pre-approved. - **Evidence against:** The installer preserves an existing file and offers an environment-variable opt-out., No network endpoint or credential collection was found in the inspected install path. ## Affected versions and remediation This report applies to jpcode-cli@1.18.37. - Avoid installing jpcode-cli@1.18.37. 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.

High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 96.0% - **Path:** postinstall.mjs - **Public source:** [View source]() The postinstall script copies bundled agent and command files into the user's global OpenCode configuration.
