Prior to 10.34.5 and 11.11.0, pnpm accepts a scoped path traversal in a tarball dependency's package.json manifest name because pnpm11/resolving/npm-resolver/src/pickPackage.ts rejects slash characters only for unscoped names. During pnpm install, the unvalidated name reaches raw path joins in pnpm11/installing/deps-resolver/src/resolvePeers.ts, pnpm11/installing/deps-resolver/src/index.ts, and pnpm11/deps/graph-builder/src/lockfileToDepGraph.ts, causing package extraction outside node_modules and allowing attacker-controlled files to overwrite arbitrary filesystem paths even when --ignore-scripts is used. The overwrite can replace shell startup files, Git hooks, or installed package code and lead to code execution. This issue is fixed in versions 10.34.5, and 11.11.0.","epss":{"date":"2026-11-03","percentile":0.50084,"score":0.00626},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://github.com/pnpm/pnpm/security/advisories/GHSA-vq4v-j7r6-jq4m"}],"kev":null,"metrics":[{"score":7.5,"severity":"high","source":"CNA: GitHub_M","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},{"score":7.5,"severity":"high","source":"NVD: security-advisories@github.com","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"}],"modifiedAt":1793747877270,"publishedAt":1788210729196,"references":[{"source":"CNA: GitHub_M","tags":["x_refsource_CONFIRM"],"url":"https://github.com/pnpm/pnpm/security/advisories/GHSA-vq4v-j7r6-jq4m"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/pnpm/pnpm/pull/12872"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/pnpm/pnpm/pull/12890"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/pnpm/pnpm/commit/51300fd41c5e4c8f47635108e373cc3d1f324fa7"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/pnpm/pnpm/commit/78e29fe5583a1e5d69ea05e414eff310f78d5ed9"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/pnpm/pnpm/releases/tag/v10.34.5"},{"source":"CNA: GitHub_M","tags":["x_refsource_MISC"],"url":"https://github.com/pnpm/pnpm/releases/tag/v11.11.0"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://github.com/pnpm/pnpm/security/advisories/GHSA-vq4v-j7r6-jq4m"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/pnpm/pnpm/commit/51300fd41c5e4c8f47635108e373cc3d1f324fa7"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/pnpm/pnpm/commit/78e29fe5583a1e5d69ea05e414eff310f78d5ed9"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/pnpm/pnpm/pull/12872"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/pnpm/pnpm/pull/12890"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/pnpm/pnpm/releases/tag/v10.34.5"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/pnpm/pnpm/releases/tag/v11.11.0"},{"source":"security-advisories@github.com","tags":[],"url":"https://github.com/pnpm/pnpm/security/advisories/GHSA-vq4v-j7r6-jq4m"},{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":[],"url":"https://github.com/pnpm/pnpm/security/advisories/GHSA-vq4v-j7r6-jq4m"},{"source":"OSV / GitHub Security Advisories","tags":["advisory"],"url":"https://github.com/advisories/GHSA-vq4v-j7r6-jq4m"},{"source":"OSV / GitHub Security Advisories","tags":["osv"],"url":"https://osv.dev/vulnerability/GHSA-vq4v-j7r6-jq4m"}],"remediation":[{"kind":"fix","source":"OSV GHSA-vq4v-j7r6-jq4m","text":"pnpm (npm): OSV reports a fixed version 10.34.5.
