{"id":"CVE-2026-101043","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-101043","summary":"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…","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.","published":"2026-09-27T17:02:33.119Z","modified":"2026-09-27T17:02:33.119Z","cvss":{"score":7.4,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/pnpm/pnpm/security/advisories/GHSA-vx52-2968-3vc6"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/pnpm-11.0.0-before-11.11.0-environment-variable-exfiltration-via-proxy-settings"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-27T17:02:33.119Z"}}
