Existing agent instructions and capabilities can be replaced without an explicit setup command or ownership check. - **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:** 0.1.0-beta.193 - **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. Automatic installation replaces files in an existing Claude agent control surface. It can reach the parent workspace and does not verify that matching files belong to this package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-06T09:41:03.074Z - **Finished:** 2026-10-06T09:42:53.480Z - **Download time:** 1275 ms - **Static scan time:** 145 ms - **AI review time:** 108985 ms - **Total time:** 110406 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:** Automatic installation replaces files in an existing Claude agent control surface. It can reach the parent workspace and does not verify that matching files belong to this package. - **Trigger:** npm postinstall in a NextSpark consumer project with an existing project or parent .claude directory. - **Impact:** Existing agent instructions and capabilities can be replaced without an explicit setup command or ownership check. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/setup.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-06T09:42:53.480Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle invokes setup, which recursively copies shipped templates over matching agent, command, and skill files. - **Attack narrative:** Installing the package in a qualifying project automatically locates an existing .claude directory, potentially at the parent workspace level. The lifecycle then runs setup there and replaces matching agent instructions, commands, and skills with package content. The dependency and directory checks limit activation but do not establish consent or ownership of the affected control surface. - **Rationale:** Inspected source establishes automatic, unconsented mutation of a broad AI-agent control surface, which meets the blocking policy. The NextSpark guard does not restrict writes to verified package-owned files. - **Files touched:** .claude ### 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 scripts/postinstall.mjs during installation., The hook checks for NextSpark dependencies, but accepts any existing .claude directory, including the parent workspace directory., The hook launches setup.mjs with the discovered agent directory's parent as its working directory., Setup targets .claude and overwrites matching agents, commands, skills, templates, workflows, and documentation without checking ownership or obtaining consent. - **Evidence against:** The lifecycle is limited to NextSpark projects with an existing .claude directory., Setup preserves existing non-schema configuration files and session contents., No credential exfiltration or remote payload execution was identified in the inspected lifecycle code. ## Affected versions and remediation This report applies to @nextsparkjs/ai-workflow@0.1.0-beta.193. - Avoid installing @nextsparkjs/ai-workflow@0.1.0-beta.193. 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.
