CVE-2025-69263 (GCVE-0-2025-69263)

Title

pnpm Lockfile Integrity Bypass Allows Remote Dynamic Dependencies

Summary

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

GHSA-7VHP-VF5G-R2FW

Vulnerability from github – Published: 2026-01-07 19:06 – Updated: 2026-01-08 20:05

Summary

pnpm Has Lockfile Integrity Bypass that Allows Remote Dynamic Dependencies

Details

Summary

HTTP tarball dependencies (and git-hosted tarballs) are stored in the lockfile without integrity hashes. This allows the remote server to serve different content on each install, even when a lockfile is committed.

Details

When a package depends on an HTTP tarball URL, pnpm's tarball resolver returns only the URL without computing an integrity hash:

resolving/tarball-resolver/src/index.ts:

return {
  resolution: {
    tarball: resolvedUrl,
    // No integrity field
  },
  resolvedVia: 'url',
}

The resulting lockfile entry has no integrity to verify:

remote-dynamic-dependency@http://example.com/pkg.tgz:
  resolution: {tarball: http://example.com/pkg.tgz}
  version: 1.0.0

Since there is no integrity hash, pnpm cannot detect when the server returns different content.

This affects: - HTTP/HTTPS tarball URLs ("pkg": "https://example.com/pkg.tgz") - Git shorthand dependencies ("pkg": "github:user/repo") - Git URLs ("pkg": "git+https://github.com/user/repo")

npm registry packages are not affected as they include integrity hashes from the registry metadata.

PoC

See attached pnpm-bypass-integrity-poc.zip

The POC includes: - A server that returns different tarball content on each request - A malicious-package that depends on the HTTP tarball - A victim project that depends on malicious-package

To run:

cd pnpm-bypass-integrity-poc
./run-poc.sh

The output shows that each install (with pnpm store prune between them) downloads different code despite having a committed lockfile.

Impact

An attacker who publishes a package with an HTTP tarball dependency can serve different code to different users or CI/CD environments. This enables:

Targeted attacks based on request metadata (IP, headers, timing)
Evasion of security audits (serve benign code during review, malicious code later)
Supply chain attacks where the malicious payload changes over time

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.

Severity

7.5 (High)
