Prior to 10.34.0 and 11.4.0, pnpm allows a transitive dependency alias from registry package metadata to contain path traversal segments. During install, pnpm later uses that alias as a filesystem path when linking dependency nodes. As a result, a registry package can cause `pnpm install --ignore-scripts` to replace paths in the current project with symlinks to attacker-controlled dependency package directories. This vulnerability is fixed in 10.34.0 and 11.4.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-23"],"references":["https://github.com/pnpm/pnpm/security/advisories/GHSA-hwx4-2j3j-g496","https://github.com/pnpm/pnpm/security/advisories/GHSA-hwx4-2j3j-g496"],"products":["pnpm:pnpm"],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-50016","score":0.00527,"percentile":0.44684,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-hwx4-2j3j-g496","url":"https://osv.dev/vulnerability/GHSA-hwx4-2j3j-g496","summary":"pnpm: Transitive dependency alias path traversal allows project path override via symlink replacement","modified":"2026-06-26T23:11:30.381440Z","packages":[{"ecosystem":"npm","name":"pnpm","purl":"pkg:npm/pnpm","ranges":["<10.34.0"],"fixed":["10.34.0"]},{"ecosystem":"npm","name":"pnpm","purl":"pkg:npm/pnpm","ranges":[">=11.0.0 <11.4.0"],"fixed":["11.4.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
