{"id":"CVE-2026-48995","aliases":["GHSA-hg3w-7f8c-63hp"],"url":"https://o3.security/vulnerability/CVE-2026-48995","summary":"pnpm: Tarball hash of GitHub git dependencies is not stored in lockfile","details":"pnpm is a package manager. 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.","published":"2026-06-25T16:58:57.536Z","modified":"2026-08-12T03:51:31.357544651Z","cvss":null,"epss":{"score":0.00161,"percentile":0.05689,"asOf":"2026-08-11"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"pnpm","fixedVersion":"10.33.4"},{"ecosystem":"npm","name":"pnpm","fixedVersion":"11.0.7"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48995.json"},{"type":"ADVISORY","url":"https://github.com/pnpm/pnpm/security/advisories/GHSA-hg3w-7f8c-63hp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48995"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:31.357544651Z"}}
