{"cve":"CVE-2026-50017","nvd":{"published":"2026-06-25T18:16:39.433","modified":"2026-06-30T19:04:10.207","status":"Analyzed","description":"pnpm is a package manager. Prior to 10.34.0 and 11.4.0, pnpm can send user-level unscoped npm authentication credentials to a registry chosen by a repository-local .npmrc file. In the reproduced case, the user's npm config contains a default registry and an unscoped _authToken. The repository does not provide a token-bearing auth line. It only sets registry= to a different registry URL. During normal pnpm metadata/install workflows, pnpm binds the user-origin unscoped credential to the repository-selected registry and sends it as an Authorization header. This vulnerability is fixed in 10.34.0 and 11.4.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-200","CWE-522"],"references":["https://github.com/pnpm/pnpm/security/advisories/GHSA-cjhr-43r9-cfmw"],"products":["pnpm:pnpm"],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-50017","score":0.00437,"percentile":0.38013,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-cjhr-43r9-cfmw","url":"https://osv.dev/vulnerability/GHSA-cjhr-43r9-cfmw","summary":"pnpm binds unscoped user-level npm auth credentials to a repository-selected registry","modified":"2026-06-26T23:26:34.872645Z","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).
