Overview
pnpm is a Fast, disk space efficient package manager
Affected versions of this package are vulnerable to Use of Weak Hash for path shortening. An attacker can cause collisions in file paths, leading to the overwriting of indirect package dependencies by manipulating package names and versions to generate the same hash value.
Note:
This is only exploitable if the package names and versions are specifically crafted to exceed 120 characters and share the same hash output.
