pnpm is a package manager. Prior to 10.34.0 and 11.4.0, pnpm passes the lockfile-controlled git resolution.commit value to git fetch without a -- separator or commit-format validation. For git dependencies fetched through the shallow-fetch path, a malicious lockfile can replace the expected 40-character commit hash with a Git option such as --upload-pack=<command>. For SSH and local transports, --upload-pack can execute the supplied command. HTTPS transports ignore --upload-pack, so the practical attack surface is primarily SSH or local git dependencies. This vulnerability is fixed in 10.34.0 and 11.4.0.

A flaw was found in pnpm, a package manager. An attacker could exploit this vulnerability by providing a malicious lockfile, which could lead to arbitrary code execution. This occurs because pnpm incorrectly processes git dependency information, allowing a crafted input to execute unauthorized commands during the fetching of git dependencies, particularly for SSH and local transports.

This Moderate severity flaw in pnpm allows for arbitrary code execution. The vulnerability arises from pnpm's improper handling of git dependency commit values from a malicious lockfile, specifically when using SSH or local git transports. Red Hat products utilizing pnpm, such as Konflux, Red Hat Build of Keycloak, Enterprise Application Platform, and Red Hat AMQ, are affected if they process untrusted pnpm-lock.yaml files with SSH or local git dependencies. Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
