Doc Text:
A flaw was found in pnpm, a package manager. A remote attacker could exploit a path traversal vulnerability by crafting a malicious `pnpm-lock.yaml` file. When a user installs dependencies from such a repository, pnpm incorrectly processes package names from the `configDependencies` section, leading to the creation of symbolic links outside the intended directory. This allows an attacker to achieve arbitrary file writes within the victim's project directory, potentially extending to other areas of the filesystem.

Description OSIDB Bzimport 2026-07-06 16:01:42 UTC
pnpm is a package manager. Prior to 10.34.4 and 11.8.0, pnpm accepts package names from the env lockfile configDependencies section and uses those names directly when creating config dependency symlinks under node_modules/.pnpm-config. A malicious repository can commit a crafted pnpm-lock.yaml whose env-lockfile document contains a traversal-shaped config dependency name. During pnpm install, pnpm installs the config dependency and creates a symlink at a path derived from that name. This vulnerability is fixed in 10.34.4 and 11.8.0.
