Remote code download and execution detected

100% confidenceline 34

curl -sSL https://raw.githubusercontent.com/langchain-ai/langsmith-cli/main/scripts/install.sh | sh

A remote resource is downloaded with curl/wget and piped directly into a shell interpreter (optionally via sudo). The downloaded script runs with no integrity check (no checksum/signature), so a compromised server, MITM, or hijacked URL leads to arbitrary code execution. Download to a file, verify it (e.g. sha256sum -c against a pinned digest, or a signature), then execute it.criticalvulnAML.T0050AML.T0053AML.T0072LLM05:2025LLM06:2025

Credential exposure risk in documentationmediumcredential theftAML.T0055AML.T0037LLM02:2025

The documentation encourages users to set API keys as environment variables or pass them as CLI flags, which may lead to accidental exposure in shell history or process logs.
