8.2 highCVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:H/A:LCVE-2026-59195
High (8.2) in pnpm pnpm. EPSS 0.4% chance of exploitation in the next 30 days. Fixed in pnpm 10.34.4, 11.8.0.
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.
