Prior to 10.33.4 and 11.0.7, a malicious codeload.github.com server can serve whatever tarball it wants and pnpm will install it regardless of the lockfile. The lockfile does not store the hash of the dependencies from https://codeload.github.com. This means that if this server was compromised or a person's machine configuration was compromised, pnpm would download and install these dependencies. This vulnerability is fixed in 10.33.4 and 11.0.7.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U","score":4.8},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","score":7.5},"cwes":["CWE-353"],"references":["https://github.com/pnpm/pnpm/security/advisories/GHSA-hg3w-7f8c-63hp","https://github.com/pnpm/pnpm/security/advisories/GHSA-hg3w-7f8c-63hp"],"products":["pnpm:pnpm"],"source":"nvd","synced_at":"2026-10-19T22:41:17.107060303+00:00"},"epss":{"cve":"CVE-2026-48995","score":0.00171,"percentile":0.06463,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-hg3w-7f8c-63hp","url":"https://osv.dev/vulnerability/GHSA-hg3w-7f8c-63hp","summary":"pnpm: Tarball hash of GitHub git dependencies is not stored in lockfile","modified":"2026-06-26T22:11:31.075929Z","packages":[{"ecosystem":"npm","name":"pnpm","purl":"pkg:npm/pnpm","ranges":["<10.33.4"],"fixed":["10.33.4"]},{"ecosystem":"npm","name":"pnpm","purl":"pkg:npm/pnpm","ranges":[">=11.0.0 <11.0.7"],"fixed":["11.0.7"]}]}],"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).
