Detailsinfo

A vulnerability has been found in pnpm up to 10.25.x and classified as problematic. Affected by this vulnerability is an unknown part. The manipulation with an unknown input leads to a code download vulnerability. The CWE definition for the vulnerability is CWE-494. The product downloads source code or an executable from a remote location and executes the code without sufficiently verifying the origin and integrity of the code. As an impact it is known to affect confidentiality. The summary by CVE is:

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.
