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:** 2.0.3 - **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. A postinstall hook can modify a globally installed user's Claude plugin settings and cache records for context-mode. The runtime also offers user- or agent-invoked code execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-09T23:24:59.969Z - **Finished:** 2026-09-09T23:26:06.164Z - **Download time:** 760 ms - **Static scan time:** 5083 ms - **AI review time:** 60348 ms - **Total time:** 66195 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:** A postinstall hook can modify a globally installed user's Claude plugin settings and cache records for context-mode. The runtime also offers user- or agent-invoked code execution. - **Trigger:** Installing the package globally triggers the configuration repair; invoking ctx\_execute triggers code execution. - **Impact:** The package can re-enable its own Claude extension during a global install, and a host that grants its MCP tool access can execute supplied code. - **Evidence paths:** package.json, scripts/postinstall.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-09T23:26:06.164Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall plugin re-enablement and MCP code-execution capability. - **Rationale:** The package has a real automatic agent-extension mutation and a powerful execution capability, so it warrants a warning. Source inspection did not substantiate the scanner's claimed remote-code execution or command-output exfiltration. - **Files touched:** ~/.claude/settings.json, ~/.claude/plugins/installed\_plugins.json, ~/.claude/plugins/cache ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The automatic postinstall hook runs package code on installation., On global installs, it edits Claude settings to enable this package's plugin., The runtime exposes a tool that accepts source code for execution. - **Evidence against:** The Claude configuration changes are limited to the package's own plugin key and preserve an explicit false opt-out in settings.json., The inspected URL-fetch code constructs local helper code and includes SSRF protections; no remote response was passed into an execution sink., No credential harvesting, exfiltration endpoint, self-dependency, or covert payload execution was found. ## Affected versions and remediation This report applies to @mxalbert/context-mode@2.0.3. - Review the evidence and your use of @mxalbert/context-mode@2.0.3 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.
