Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Installing the package triggers a postinstall hook that silently fetches and executes a third-party installer. It then configures a program in the user's home directory. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-08T01:30:32.436Z - **Finished:** 2026-09-08T01:31:26.660Z - **Download time:** 756 ms - **Static scan time:** 86 ms - **AI review time:** 53382 ms - **Total time:** 54224 ms The recorded confidence comes from the underlying analysis.

It then configures a program in the user's home directory. - **Trigger:** npm installation with lifecycle scripts enabled, unless CUBIC\_DISABLE\_GIT\_AI is set. - **Impact:** A remote GitHub release script runs with the installing user's permissions and can install or alter git-ai outside the package directory. - **Evidence paths:** package.json, postinstall.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-08T01:31:26.660Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall remote-script execution and home-directory tool configuration. - **Attack narrative:** The npm postinstall hook automatically calls setupGitAi. If git-ai is missing, it downloads an install script from GitHub and pipes it into Bash on non-Windows systems or PowerShell IEX on Windows, without an integrity check or interactive consent. It then invokes the installed home-directory binary to set configuration values. This is an automatic install-time remote-code execution path that mutates software outside the package. - **Rationale:** The package performs unconsented remote script execution and external tool configuration from a postinstall hook. This is concrete install-hook abuse, even though the snapshot contains no direct credential theft code. - **Files touched:** postinstall.mjs, bin/cubic, ~/.git-ai/bin/git-ai - **Network endpoints:** github.com ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest runs postinstall automatically during npm installation., Postinstall unconditionally invokes git-ai setup after its binary setup., When git-ai is absent, the hook silently downloads and executes a remote installer through Bash or PowerShell., The hook locates a home-directory git-ai binary and applies configuration changes to it. - **Evidence against:** The preinstall hook only logs platform information., The coding-agent setup command is guarded by interactive-terminal checks., No source in this snapshot harvests credentials or sends local data to a network endpoint. ## Affected versions and remediation This report applies to @cubic-dev-ai/cli@1.10.7. - Avoid installing @cubic-dev-ai/cli@1.10.7. 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.
