## Verdict summary
**Blocked & quarantined** — Arbitrary remote JavaScript can execute in the consuming project environment with Node require access

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Block by default
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 3.3.7
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block.

AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

Source inspection confirms a non-package-aligned hidden downloader/evaluator path from index.js to lib/caller.js. This is concrete malicious runtime remote code execution, not just a noisy static signal.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Malicious
- **Recorded analysis confidence:** 99.0%

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** Confirmed runtime remote code execution. Calling the exported middleware starts a detached child Node process that downloads JavaScript from IPFS-hosted content and executes it with require access.

- **Trigger:** User/application imports package and invokes exported middleware function

- **Impact:** Arbitrary remote JavaScript can execute in the consuming project environment with Node require access

- **Evidence paths:** package.json, index.js, lib/caller.js, file.js

- **Review source:** ai\_review

- **Reviewed:** 2026-07-09T23:02:16.282Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** detached child process downloads and evaluates remote payload

- **Attack narrative:** The package presents copied pino-like files, but index.js exports a middleware wrapper that secretly spawns a detached Node child. That child runs lib/caller.js, fetches code from an IPFS gateway, extracts a cookie field, and evaluates it with Function.constructor while passing require, enabling arbitrary remote payload execution when the package API is used.

- **Rationale:** Source inspection confirms a non-package-aligned hidden downloader/evaluator path from index.js to lib/caller.js. This is concrete malicious runtime remote code execution, not just a noisy static signal.

- **Files touched:** index.js, lib/caller.js

- **Network endpoints:** https://bronze-improved-gibbon-411.mypinata.cloud/ipfs/bafkreigjnxn5vnn34rc5r43ajwwkmk4akqpm4awmq5gdhakgszpeqiffsu

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** index.js exports middleware that spawns detached node process running ./lib/caller.js when invoked, lib/caller.js fetches remote data from mypinata.cloud IPFS URL with axios, lib/caller.js reads response .data.cookie and executes it via new Function.constructor('require', s), README/docs appear copied from pino while package name/manifest do not match that codebase, package.json adds axios/request/sqlite3 dependencies despite no package-aligned functionality requiring them

- **Evidence against:** package.json has no preinstall/install/postinstall lifecycle hooks, No direct credential or filesystem harvesting is visible in inspected source before remote payload execution

## Affected versions and remediation

This report applies to type-slint@3.3.7.

- Avoid installing type-slint@3.3.7. 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.
