{"id":"CVE-2026-59195","aliases":["GHSA-qrv3-253h-g69c"],"url":"https://o3.security/vulnerability/CVE-2026-59195","summary":"pnpm: Path traversal in configDependencies env lockfile allows symlink creation outside node_modules/.pnpm-config","details":"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.","published":"2026-07-06T15:21:03.101Z","modified":"2026-09-06T03:30:58.078664414Z","cvss":{"score":8.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:H/A:L"},"epss":{"score":0.00401,"percentile":0.33445,"asOf":"2026-09-07"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"pnpm","fixedVersion":"10.34.4"},{"ecosystem":"npm","name":"pnpm","fixedVersion":"11.8.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59195.json"},{"type":"ADVISORY","url":"https://github.com/pnpm/pnpm/security/advisories/GHSA-qrv3-253h-g69c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-59195"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-06T03:30:58.078664414Z"}}
