The binary is later run by the tfcode command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-21T17:54:35.319Z - **Finished:** 2026-08-21T17:55:42.819Z - **Download time:** 1774 ms - **Static scan time:** 130 ms - **AI review time:** 65595 ms - **Total time:** 67500 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation fetches a mutable latest release archive and stages its native binary without a source-visible integrity check. The binary is later run by the tfcode command. - **Trigger:** npm postinstall on a platform lacking bin/tfcode; later explicit tfcode invocation. - **Impact:** A compromised or changed release endpoint can replace the executable subsequently launched by the CLI. - **Evidence paths:** package.json, postinstall.mjs, bin/tfcode.js, python/tf\_sync/config.py - **Review source:** ai\_review - **Reviewed:** 2026-08-21T17:55:42.819Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote native-payload staging via unpinned release download - **Rationale:** Source establishes a postinstall-time mutable remote binary staging path and a user-level pip mutation, warranting a warning. It does not establish concrete malicious behavior, exfiltration, or broad AI-agent control-surface modification. - **Files touched:** postinstall.mjs, bin/tfcode, bin/app, bin/tfcode.js - **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:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for:** postinstall resolves an unpinned latest release, then downloads its platform archive with curl., The downloaded archive is extracted and its binary is copied into bin/ and made executable., postinstall also runs pip install --user for several packages. - **Evidence against:** No source evidence of credential harvesting, exfiltration, or foreign AI-agent configuration writes., The CLI launcher only executes the package-local binary after an explicit tfcode invocation., Python integration reads named ToothFairyAI credentials for its documented client configuration. ## Public findings ### 1.
