Summary
pnpm Lockfile Integrity Bypass Allows Remote Dynamic Dependencies
Details

pnpm is a package manager. Versions 10.26.2 and below store HTTP tarball dependencies (and git-hosted tarballs) in the lockfile without integrity hashes. This allows the remote server to serve different content on each install, even when a lockfile is committed. An attacker who publishes a package with an HTTP tarball dependency can serve different code to different users or CI/CD environments. The attack requires the victim to install a package that has an HTTP/git tarball in its dependency tree. The victim's lockfile provides no protection. This issue is fixed in version 10.26.0.

Severity
