Doc Text:
A flaw was found in pnpm, a package manager. This vulnerability allows a remote attacker to serve malicious software packages if the `codeload.github.com` server is compromised or a user's machine configuration is tampered with. The issue arises because pnpm does not verify the integrity of dependencies downloaded from `https://codeload.github.com` against its lockfile. This could lead to the installation of unverified and potentially malicious code, resulting in arbitrary code execution on the affected system.

Description OSIDB Bzimport 2026-06-25 18:02:52 UTC
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.
