{"id":"CVE-2026-50014","aliases":["GHSA-p4xf-rf54-rj3x"],"url":"https://o3.security/vulnerability/CVE-2026-50014","summary":"pnpm: Git Fetch Argument Injection via Lockfile resolution.commit","details":"pnpm is a package manager. Prior to 10.34.0 and 11.4.0, pnpm passes the lockfile-controlled git resolution.commit value to git fetch without a -- separator or commit-format validation. For git dependencies fetched through the shallow-fetch path, a malicious lockfile can replace the expected 40-character commit hash with a Git option such as --upload-pack=<command>. For SSH and local transports, --upload-pack can execute the supplied command. HTTPS transports ignore --upload-pack, so the practical attack surface is primarily SSH or local git dependencies. This vulnerability is fixed in 10.34.0 and 11.4.0.","published":"2026-06-25T16:51:16.652Z","modified":"2026-08-12T03:51:25.458683588Z","cvss":{"score":6.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:N"},"epss":{"score":0.00263,"percentile":0.17992,"asOf":"2026-08-11"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"pnpm","fixedVersion":"10.34.0"},{"ecosystem":"npm","name":"pnpm","fixedVersion":"11.4.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50014.json"},{"type":"ADVISORY","url":"https://github.com/pnpm/pnpm/security/advisories/GHSA-p4xf-rf54-rj3x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-50014"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:25.458683588Z"}}
