It retrieves a remote shell installer and executes it without an interactive consent gate. - **Trigger:** Installing the package with lifecycle scripts enabled. - **Impact:** Installation can execute remotely supplied code and mutate a foreign AI-agent tool's user-level configuration. - **Evidence paths:** package.json, postinstall.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-27T01:37:16.537Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall invokes git-ai setup, streams a GitHub installer into bash when needed, and sets git-ai configuration values. - **Attack narrative:** During package installation, npm runs postinstall. The hook calls git-ai setup unconditionally after its own binary setup. If the separate tool is missing or outdated, it downloads a versioned installer from GitHub and pipes it directly to bash, then changes that tool's configuration. Although an opt-out exists, the default install path performs this foreign user-environment mutation automatically. - **Rationale:** The package uses an automatic install hook to execute a remotely fetched shell installer and configure a separate AI-related tool in the user's environment. This is an unconsented lifecycle mutation of a foreign control surface. - **Files touched:** package.json, postinstall.mjs - **Network endpoints:** https://github.com/git-ai-project/git-ai/releases/download/${GIT\_AI\_VERSION}/install.sh ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest automatically runs preinstall and postinstall scripts during npm installation., The postinstall path always invokes git-ai setup after binary setup., When git-ai is absent or old, postinstall downloads its installer from GitHub and pipes it to bash., The install hook applies configuration to the user's git-ai installation. - **Evidence against:** The hook supports an environment-variable or persisted opt-out for git-ai setup. ## Affected versions and remediation This report applies to @cubic-dev-ai/cli@1.14.2. - Avoid installing @cubic-dev-ai/cli@1.14.2. 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.
