Summary

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.
