CVE-2025-69263: pnpm Lockfile Integrity Bypass Allows Remote Dynamic Dependencies

• Severity: high (CVSS 8.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days
• Public exploit or detection template: yes

• Weakness: CWE-494

Description

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.

Affected products

• pnpm: before 10.26.0 — fixed in 10.26.0

How to fix

Upgrade to a fixed version: pnpm 10.26.0. Check the vendor advisory for mitigations.
