CVE-2026-48995 Details
Description
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 this server was compromised or a person's machine configuration was compromised, pnpm would download and install these dependencies. This vulnerability is fixed in 10.33.4 and 11.0.7.
A vulnerability exists in pnpm, a package manager, in versions prior to 10.33.4 and 11.0.0 through 11.0.7. The issue arises because the pnpm lockfile does not store the hash of dependencies fetched from codeload.github.com. As a result, a malicious or compromised codeload server could serve harmful tarballs that pnpm would install, bypassing the lockfile's safeguards. This vulnerability affects users relying on GitHub Git dependencies.
Users can upgrade to pnpm version 10.33.4 or 11.0.7 to address this vulnerability.
