It also changes this package's local cubic launcher and may launch the package binary for interactive setup. - **Trigger:** npm install of @cubic-dev-ai/cli@1.10.5 - **Impact:** A remotely supplied installer executes with the installing user's privileges and can modify the user environment. - **Evidence paths:** package.json, postinstall.mjs, preinstall.mjs, bin/cubic, bin/cubic.wrapper, bin/cubic.cmd, git-ai.json - **Review source:** ai\_review - **Reviewed:** 2026-08-20T16:15:49.352Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall curl-to-bash remote installer execution - **Rationale:** The lifecycle script performs unprompted remote code execution during installation, creating a real supply-chain risk. The URL is version-pinned and no direct malicious behavior is shown, so a warning rather than a block is warranted. - **Files touched:** postinstall.mjs, bin/cubic, bin/cubic.wrapper, ~/.git-ai/bin/git-ai - **Network endpoints:** https://github.com/git-ai-project/git-ai/releases/download/${GIT\_AI\_VERSION}/install.sh ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** postinstall silently downloads and pipes a GitHub release installer to bash., The remote installer is invoked during npm postinstall, without an explicit user command., postinstall rewrites its bin entrypoint and invokes optional setup in interactive installs. - **Evidence against:** The download URL uses a fixed, validated git-ai version., git-ai installation can be disabled with CUBIC\_DISABLE\_GIT\_AI=true., No credential harvesting, exfiltration, destructive action, or hidden payload is present in inspected package files. ## Affected versions and remediation This report applies to @cubic-dev-ai/cli@1.10.5. - Review the evidence and your use of @cubic-dev-ai/cli@1.10.5 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
