The package can change Claude command hooks and repository files without a separate user setup action. - **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:** 1.30.1 - **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 modifies a detected consumer repository. It installs command hooks into the consumer's AI-agent settings and adds further repository controls. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-09T11:01:03.910Z - **Finished:** 2026-09-09T11:02:29.906Z - **Download time:** 260 ms - **Static scan time:** 1842 ms - **AI review time:** 83891 ms - **Total time:** 85996 ms The recorded confidence comes from the underlying analysis.

It installs command hooks into the consumer's AI-agent settings and adds further repository controls. - **Trigger:** npm install runs the postinstall lifecycle hook. - **Impact:** The package can change Claude command hooks and repository files without a separate user setup action. - **Evidence paths:** package.json, skills/suppa-entity-code/scripts/postinstall.mjs, skills/suppa-entity-code/scripts/install-entity-code-guards.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-09T11:02:29.906Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic consumer-project AI-agent hook and configuration mutation. - **Attack narrative:** During npm installation, postinstall uses the invoking directory to find a consumer project and executes a bundled installer against it. The installer writes command hooks for Claude write and stop events, then modifies agent instruction files, Git hook configuration, CI configuration, and the consumer package manifest. These are automatic changes to a foreign project and AI-agent control surface, not an explicit user-invoked setup operation. - **Rationale:** The automatic postinstall chain mutates a foreign consumer repository's AI-agent control surface and related project controls. This is concrete install-hook abuse despite its Suppa-specific guards and opt-out. - **Files touched:** .claude/settings.json, AGENTS.md, CLAUDE.md, .githooks/pre-commit, .gitlab/suppa-schema-gate.yml, package.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs a postinstall script automatically during npm installation., The postinstall locates the consumer repository from INIT\_CWD and runs a bundled installer there., That installer adds command hooks to the consumer's Claude settings for write and stop events., It also writes agent instruction files, a Git hook, CI configuration, and a consumer package script without an explicit setup command. - **Evidence against:** The repository mutation is limited to projects identified as Suppa applications and has an environment-variable opt-out., No runtime self-dependency, credential exfiltration, or unrelated network endpoint was found in the inspected code., The normal network code is for the stated Suppa authentication and API functions. ## Affected versions and remediation This report applies to suppa-mcp-2@1.30.1. - Avoid installing suppa-mcp-2@1.30.1. 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.
