Vulnerability Type: Unpinned third-party dependency and unsafe package execution
Risk Level: Mediumbash # Global install npm install -g pinets-cli # Or run directly with npx (no install needed) npx pinets-cli run indicator.pine --symbol BTCUSDT -qTechnical Analysis
The documented commands install or execute
pinets-cliwithout specifying a reviewed version or verifying an integrity digest. Consequently, npm resolves whichever package version is current when the command runs.npm install -ginstalls the package globally and may execute package lifecycle scripts with the privileges of the invoking user. Thenpxcommand may download and immediately execute the latest available package when it is not already installed locally. Neither workflow uses a lockfile, an integrity hash, a verified artifact, or an option that prevents automatic network installation.This creates a supply-chain exposure: compromise of the npm package, its maintainer account, the registry delivery path, or a transitive dependency could cause arbitrary attacker-controlled code to run. The referenced GitHub homepage does not ensure that the npm artifact being executed corresponds to a reviewed repository revision.
Attack Path
- An attacker compromises the npm publisher account, package release process, or one of the package's transitive dependencies.
- The attacker publishes a malicious version that includes hostile runtime code or npm lifecycle scripts.
- A user or agent follows the documented unpinned
npm install -g pinets-cliornpx pinets-cli ...instruction. - npm resolves and downloads the attacker-controlled release because no trusted version or integrity value is enforced.
- Malicious lifecycle or application code executes with the privileges and environment access of the invoking user.
- The payload may access files and credentials ...[truncated 870 chars]

Remediation Suggestions
- Pin
pinets-clito an explicitly reviewed version in every installation and execution example, such aspinets-cli@X.Y.Z. - Prefer a project-local dependency recorded in
package.jsonand a committed lockfile rather than a global installation. - Use
npm ciwith a reviewed lockfile in automated environments so dependency resolution cannot silently drift. - Verify npm package provenance, publisher identity, release signatures where available, and the package's integrity digest before execution.
- Configure an explicit trusted npm registry and prohibit unexpected registry overrides.
- Avoid automatic downloads through plain
npx. Require a preinstalled, verified binary or usenpx --no-installafter validating the local installation. - Install and execute the tool in a sandbox or container with minimal filesystem permissions, no unnecessary secrets, restricted network access, and a non-privileged account.
- Review package lifecycle scripts and consider disabling them during installation with
--ignore-scriptsif the package can operate without them. - Document the expected artifact version and checksum so users and agents can fail closed when verification does not succeed.
