Automated Dependency Build Script Allowlisting and Auditing

C7/10May 19, 2026

WhatA CI/CD and local development tool that blocks all pre/post-install scripts by default across npm, pip, and other package managers, with an audited allowlist and one-command approval workflow.

SignalMultiple commenters point out that these attacks fundamentally rely on pre/post-install scripts that most packages don't actually need, and that pnpm's allowBuilds feature already proves this — one user disabled all build scripts and saw zero breakage, suggesting the entire attack vector is unnecessary for most workflows.

Why Nowpnpm v11 shipped allowBuilds as a first-class feature in 2025, validating the approach, but npm (the dominant package manager) still has no equivalent, leaving the vast majority of the JS ecosystem exposed.

MarketEvery team using npm (~17M developers); monetize through enterprise dashboard for policy management. Direct gap: npm lacks this feature, pnpm has it but has minority market share.

MoatCurated allowlist database becomes the de facto standard if widely adopted — network effects as community contributions make the allowlist more comprehensive and trustworthy.
