{"schema":"threatline.record/2","record":{"id":"CVE-2026-101043","aliases":["GHSA-vx52-2968-3vc6"],"summary":"pnpm 11.0.0 before 11.11.0 Environment Variable Exfiltration via Proxy Settings","details":"pnpm versions 11.0.0 before 11.11.0 and 10.7.0 before 10.34.5 expand ${VAR} environment-variable placeholders in the httpProxy, httpsProxy, and noProxy settings read from a project's pnpm-workspace.yaml. Because the manifest is repository-controlled and the proxy keys were omitted from the request-destination key set that otherwise suppresses placeholder expansion for untrusted manifests (as already done for registry, pnprServer, registries and namedRegistries), an attacker who controls a repository's pnpm-workspace.yaml can cause a victim who clones the repository and runs a pnpm command (e.g. pnpm install) to expand environment secrets such as NPM_TOKEN or GITHUB_TOKEN into a proxy hostname or userinfo and route install traffic — and the corresponding DNS lookups — through an attacker-controlled host. The exfiltration occurs during configuration loading, before any lifecycle script executes. Fixed in pnpm 11.11.0 and 10.34.5.","categories":["Libraries & packages"],"product":"pnpm","vendor":"pnpm","ecosystem":"npm","affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-101043","source_modified_at":"2026-09-30T15:47:12.588Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"pnpm","vendor":"pnpm","versions":[{"version":"11.0.0","status":"affected","versionType":"semver","lessThan":"11.11.0"},{"version":"11.11.0","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-101043","source_modified_at":"2026-09-30T15:47:12.588Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"pnpm","vendor":"pnpm","versions":[{"version":"10.7.0","status":"affected","versionType":"semver","lessThan":"10.34.5"},{"version":"10.34.5","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-vx52-2968-3vc6","source_modified_at":"2026-09-28T03:55:58.182153770Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"pnpm","ecosystem":"npm","purl":"pkg:npm/pnpm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"11.0.0"},{"fixed":"11.11.0"}]}],"versions":[]},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-vx52-2968-3vc6","source_modified_at":"2026-09-28T03:55:58.182153770Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"pnpm","ecosystem":"npm","purl":"pkg:npm/pnpm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"10.7.0"},{"fixed":"10.34.5"}]}],"versions":[]}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-101043","source_modified_at":"2026-09-30T15:47:12.588Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"pnpm","ecosystem":null},"version":"11.11.0","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-101043","source_modified_at":"2026-09-30T15:47:12.588Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"pnpm","ecosystem":null},"version":"10.34.5","basis":"first unaffected version stated in the CVE record"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-vx52-2968-3vc6","source_modified_at":"2026-09-28T03:55:58.182153770Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"pnpm","ecosystem":"npm","purl":"pkg:npm/pnpm"},"version":"11.11.0"},{"source":"OSV","source_url":"https://osv.dev/vulnerability/GHSA-vx52-2968-3vc6","source_modified_at":"2026-09-28T03:55:58.182153770Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"pnpm","ecosystem":"npm","purl":"pkg:npm/pnpm"},"version":"10.34.5"}],"cvss":8.3,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00225,"percentile":0.12509,"score_date":"2026-10-23"},"published_at":"2026-09-27T17:02:33.119Z","modified_at":"2026-09-30T15:47:12.588Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-101043","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-30T15:47:12.588Z"},{"source":"OSV","url":"https://osv.dev/vulnerability/GHSA-vx52-2968-3vc6","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-28T03:55:58.182153770Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-101043","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","OSV","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/pnpm/pnpm/security/advisories/GHSA-vx52-2968-3vc6","tags":["exploit"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/pnpm-11.0.0-before-11.11.0-environment-variable-exfiltration-via-proxy-settings","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-30T15:47:05.650499Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"ecosystem","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-09-30T15:47:12.588Z","content_hash":"b01b149462ca81b29e78ab87514157817d4bfde69b80fa10a159e85319599ce3"}}
