@pnpm/exe is vulnerable to Authorization Bypass
59
Medium Risk
This Affects:
@pnpm/exeTL;DR
pnpm's install-time build-script policy lets dangerouslyAllowAllBuilds approve every dependency's lifecycle scripts before the per package allowBuilds denylist is checked. A workspace that sets dangerouslyAllowAllBuilds while also explicitly denying specific packages with allowBuilds still runs the denied packages' install/build scripts. This lets a dependency the project deliberately blocked execute code during pnpm install instead of staying disabled. The fix evaluates explicit allowBuilds denials before the blanket allow so a deny entry always wins.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you set dangerouslyAllowAllBuilds while also denying specific packages with allowBuilds.
