Claude Code may load and run this package through a user-level plugin registration 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:** 2.0.5 - **Selected version is latest:** No - **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. Installing the package automatically mutates Claude Code’s user-level plugin control files. It can enable this plugin and redirect a missing registered cache path to the installed package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-12T14:22:08.447Z - **Finished:** 2026-09-12T14:23:16.309Z - **Download time:** 252 ms - **Static scan time:** 3233 ms - **AI review time:** 64373 ms - **Total time:** 67862 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:** Installing the package automatically mutates Claude Code’s user-level plugin control files. It can enable this plugin and redirect a missing registered cache path to the installed package. - **Trigger:** npm installation runs the postinstall hook; the settings changes are gated to global installs, but the symlink repair is not. - **Impact:** Claude Code may load and run this package through a user-level plugin registration without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/heal-installed-plugins.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-12T14:23:16.309Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall rewrites Claude plugin settings and creates cache-path symlinks. - **Attack narrative:** The package’s automatic postinstall hook edits Claude Code’s plugin registry and settings, forcing its plugin enabled unless a false value already exists. It also repairs missing registered plugin paths by creating symlinks to the installed package. These actions alter an external AI-agent control surface during installation rather than through an explicit user setup action, creating a path for the package to be loaded by Claude Code. - **Rationale:** This is concrete automatic mutation of a foreign AI-agent control surface, including forced plugin enablement and registry-path redirection. The scope checks do not remove the unconsented postinstall behavior. - **Files touched:** ~/.claude/settings.json, ~/.claude/plugins/installed\_plugins.json, ~/.claude/plugins/cache/... ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest runs scripts/postinstall.mjs automatically after installation., The postinstall hook changes Claude Code’s user-level plugin registry and settings during a global install., The helper sets this package’s Claude plugin entry to enabled and writes the settings file., Even outside the global-install guard, postinstall can replace a missing Claude plugin cache path with a symlink to this package. - **Evidence against:** The settings helper preserves an explicit false opt-out., The registry operations are limited to this package’s plugin key and cache directory., No credential exfiltration or attacker-controlled network endpoint was confirmed from the inspected code. ## Affected versions and remediation This report applies to @mxalbert/context-mode@2.0.5. - Avoid installing @mxalbert/context-mode@2.0.5. 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.
