pnpm: hoisted install imports lockfile alias outside node_modules

State: Published
Severity: 7.1 High
Published: Jul 6, 2026
Updated: Jul 6, 2026
Reserved: Jul 2, 2026

Description

pnpm is a package manager. Prior to 10.34.4 and 11.7.0, a crafted lockfile alias could be joined directly under a hoisted node_modules directory. Traversal aliases could escape that directory, while reserved aliases such as .bin or .pnpm could overwrite pnpm-owned layout. This vulnerability is fixed in 10.34.4 and 11.7.0.
