It also installs Python packages into the user environment. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-25T02:05:08.036Z - **Finished:** 2026-08-25T02:06:05.861Z - **Download time:** 1775 ms - **Static scan time:** 146 ms - **AI review time:** 55902 ms - **Total time:** 57825 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall fetches a mutable latest release and installs its native binary without a pinned version or integrity check. It also installs Python packages into the user environment. - **Trigger:** npm installation - **Impact:** A compromised configured release host can stage native code for later tfcode execution; installation mutates the Python user environment. - **Evidence paths:** package.json, postinstall.mjs, bin/tfcode.js, bin/tfcode - **Review source:** ai\_review - **Reviewed:** 2026-08-25T02:06:05.861Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary retrieval and user-environment package installation - **Rationale:** This is not confirmed malicious behavior: defaults are vendor-aligned and no harvesting or foreign control-surface mutation was found. However, an install-time mutable remote native payload chain plus pip environment mutation warrants a warning. - **Files touched:** postinstall.mjs, bin/tfcode, bin/app, temporary tfcode-install directory, user Python package directory - **Network endpoints:** https://gitea.toothfairyai.com/api/v1/repos/ToothFairyAI/tf\_code/releases/latest, https://gitea.toothfairyai.com/ToothFairyAI/tf\_code/releases/download/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for:** postinstall resolves a remotely supplied “latest” release version., postinstall downloads and installs an unsigned platform archive at install time., postinstall also invokes pip to mutate the user Python environment. - **Evidence against:** Default download host and repository are ToothFairyAI-aligned., Writes are limited to the package bin directory and a temporary directory., No source evidence of credential harvesting, exfiltration, or foreign AI-agent config mutation. ## Public findings ### 1.
