A registry install can execute GitHub-hosted shell or PowerShell code and alter the user's git-ai tool configuration. - **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:** 1.10.8 - **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. Npm installation silently installs and configures a separate AI-related tool in the user's home directory. The remote installer is fetched and executed without source verification. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-08T13:00:47.714Z - **Finished:** 2026-09-08T13:01:32.889Z - **Download time:** 510 ms - **Static scan time:** 115 ms - **AI review time:** 44550 ms - **Total time:** 45175 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:** Npm installation silently installs and configures a separate AI-related tool in the user's home directory. The remote installer is fetched and executed without source verification. - **Trigger:** npm automatically runs postinstall when this package is installed. - **Impact:** A registry install can execute GitHub-hosted shell or PowerShell code and alter the user's git-ai tool configuration. - **Evidence paths:** package.json, postinstall.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-08T13:01:32.889Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote installer execution followed by foreign git-ai configuration. - **Attack narrative:** Installing the package triggers postinstall. Unless CUBIC\_DISABLE\_GIT\_AI is set, it checks for git-ai and, if absent, silently fetches a versioned installer from GitHub and pipes it into bash or PowerShell. It then runs the installed binary to apply configuration. This is an unconsented install-time mutation of a separate AI-related control surface and executes remote code outside the package snapshot. - **Rationale:** The package's automatic postinstall downloads and executes a foreign installer, then changes the installed tool's configuration. This is concrete install-hook abuse, not necessary local binary linking. - **Files touched:** postinstall.mjs, git-ai.json, $HOME/.git-ai/bin/git-ai - **Network endpoints:** https://github.com/git-ai-project/git-ai/releases/download/${GIT\_AI\_VERSION}/install.sh, https://github.com/git-ai-project/git-ai/releases/download/${GIT\_AI\_VERSION}/install.ps1 ### 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 postinstall automatically during npm installation., Postinstall installs the separate git-ai tool when it is absent unless an environment opt-out is set., It downloads a remote installer from GitHub and pipes it directly to bash or PowerShell execution., It then invokes git-ai to set configuration in the user's git-ai installation. - **Evidence against:** The preinstall script only prints platform information., The optional cubic setup wizard requires an interactive terminal., No source code reads credentials or sends collected local data to a separate endpoint. ## Affected versions and remediation This report applies to @cubic-dev-ai/cli@1.10.8. - Avoid installing @cubic-dev-ai/cli@1.10.8. 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.
