Description

This security bulletin contains information about 1 vulnerability.


1) Interpretation Conflict (CVE-ID: CVE-2023-37478)

The vulnerability allows a remote attacker to cause installation of a malicious package version.

The vulnerability exists due to improper handling of duplicate archive entries in tar archive parsing in tar archive extraction in pnpm when processing a crafted tarball. A remote attacker can supply a specially crafted package tarball to cause installation of a malicious package version.

The issue arises because pnpm uses the first file with a given name in the archive, while other package managers are expected to use the last matching entry after path component stripping.
