Prior to 10.34.5 and from 11.0.0 until 11.11.0, pnpm parses the package name from attacker-controlled pnpm-lock.yaml packages keys with dp.parse(depPath).name and uses it without validation in deps/graph-builder/src/lockfileToDepGraph.ts and pnpm11/deps/graph-builder/src/lockfileToDepGraph.ts. The name reaches path.join(modules, pkgName), storeController.importPackage, and pnpm11/lockfile/to-pnp/src/index.ts, allowing package contents to be written outside node_modules when a user runs pnpm install. When dangerouslyAllowAllBuilds or a matching allowBuilds entry permits lifecycle scripts, the escaped package can execute code with the user's privileges. This issue is fixed in versions 10.34.5 and 11.11.0.","published":"2026-08-31T21:17:54.033","modified":"2026-08-31T21:17:54.033","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/pnpm/pnpm/commit/51300fd41c5e4c8f47635108e373cc3d1f324fa7","label":"pnpm/pnpm@51300fd"},"references":[{"type":"WEB","url":"https://github.com/pnpm/pnpm/commit/51300fd41c5e4c8f47635108e373cc3d1f324fa7"},{"type":"WEB","url":"https://github.com/pnpm/pnpm/commit/78e29fe5583a1e5d69ea05e414eff310f78d5ed9"},{"type":"WEB","url":"https://github.com/pnpm/pnpm/pull/12872"},{"type":"WEB","url":"https://github.com/pnpm/pnpm/pull/12890"},{"type":"WEB","url":"https://github.com/pnpm/pnpm/releases/tag/v10.34.5"},{"type":"WEB","url":"https://github.com/pnpm/pnpm/releases/tag/v11.11.0"},{"type":"WEB","url":"https://github.com/pnpm/pnpm/security/advisories/GHSA-c59q-g84q-2gj5"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-31T21:17:54.033"}}
