CVE-2026-48995 pnpm: Tarball hash of GitHub git dependencies is not stored in lockfile

pnpm is a package manager. Prior to 10.33.4 and 11.0.7, a malicious codeload.github.com server can serve whatever tarball it wants and pnpm will install it regardless of the lockfile. The lockfile does not store the hash of the dependencies from https://codeload.github.com. This means that if thi...

CVE-2026-48995

CVE-2026-48995 affects pnpm, a package manager. Prior to versions 10.33.4 and 11.0.7, a malicious codeload.github.com server could serve arbitrary tarballs and pnpm would install them regardless of the lockfile because the tarball hash is not stored in the lockfile. This could enable tampering of...

CVE-2026-50014 pnpm: Git Fetch Argument Injection via Lockfile resolution.commit

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...
