A dependency installation can replace or add instructions and commands that control local AI coding agents without user consent. - **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:** 3.10.0 - **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. An automatic install hook mutates AI coding-agent configuration in the consuming project. No network attack was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-26T04:29:43.163Z - **Finished:** 2026-09-26T04:30:33.104Z - **Download time:** 510 ms - **Static scan time:** 47 ms - **AI review time:** 49383 ms - **Total time:** 49941 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:** An automatic install hook mutates AI coding-agent configuration in the consuming project. No network attack was identified. - **Trigger:** npm postinstall execution, including noninteractive CI installation. - **Impact:** A dependency installation can replace or add instructions and commands that control local AI coding agents without user consent. - **Evidence paths:** package.json, .catalyst/bin/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-26T04:30:33.104Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer selects a harness automatically, overwrites agent files, and copies agent commands into detected harness directories. - **Attack narrative:** Installing the package invokes its postinstall installer. In CI it chooses Claude Code automatically, then writes bundled agent content and commands into project agent directories. It warns that existing agent files will be overwritten and refreshes other detected harnesses as well. This is an unconsented install-time mutation of a broad AI-agent control surface. - **Rationale:** The automatic lifecycle hook performs broad, potentially destructive AI-agent configuration writes without an explicit user command or consent gate. This meets the install-control-surface blocking policy. - **Files touched:** .claude/agents, .claude/commands, .pi/agents, .pi/prompts, .codex/agents, .codex/prompts ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs its installer automatically through a postinstall hook., In CI, the installer selects the Claude harness without prompting., The installer overwrites existing agent files and copies bundled agents and commands into harness directories., The installer also refreshes other detected harness directories, beyond the selected target. ## Affected versions and remediation This report applies to catalyst-os@3.10.0. - Avoid installing catalyst-os@3.10.0. 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.
