Execute 'npm install -g pnpm@11.5.3' or use corepack to update pnpm.\n2. Audit any configured registry configurations to ensure they use secure HTTPS connections.\n3. Employ endpoint detection tools to flag suspicious file-write operations originating from Node.js applications.\n\n## References\n\n- [GitHub Pull Request #12303](https://github.com/pnpm/pnpm/pull/12303)\n- [GitHub Security Advisory GHSA-v23m-ccfg-pq9h](https://github.com/pnpm/pnpm/security/advisories/GHSA-v23m-ccfg-pq9h)\n- [CVE-2026-55700 Record](https://www.cve.org/CVERecord?id=CVE-2026-55700)\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/CVE-2026-55700) - Automated Vulnerability Intelligence*", "url": "https://gist.github.com/alon710/df5b0744014030db937f68dddaa36b9f"}, {"timestamp": "2026-06-29T21:16:55.820Z", "date_only": false, "value": "2026-06-29T21:16:55.820", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-55700", "record": "FKIE_CVE-2026-55700", "field": "lastModified"}, {"timestamp": "2026-06-29T23:02:40.273Z", "date_only": false, "value": "2026-06-29T23:02:40.273845Z", "kind": "sighting", "label": "Seen", "source": "https://bsky.app/profile/kriptabiz.bsky.social/post/3mphluarxhe2d", "record": "CVE-2026-55700", "field": "creation_timestamp", "uuid": "d353b7d3-f204-48b4-ab97-0d287ce60f5a", "content": "\u0423\u044f\u0437\u0432\u0438\u043c\u043e\u0441\u0442\u044c CVE-2026-55700 \u0432 pnpm: \u0447\u0442\u043e \u044d\u0442\u043e \u0442\u0430\u043a\u043e\u0435 \u0438 \u043a\u0430\u043a \u0437\u0430\u0449\u0438\u0442\u0438\u0442\u044c\u0441\u044f\n\n\n\nhttps://kripta.biz/posts/7F81E1CE-741F-4457-BB66-540C55BE0E59", "url": "https://bsky.app/profile/kriptabiz.bsky.social/post/3mphluarxhe2d"}, {"timestamp": "2026-08-13T17:28:25Z", "date_only": false, "value": "2026-08-13T17:28:25Z", "kind": "milestone", "label": "Published", "source": "osv_homebrew \u00b7 BREW-PNPM-CVE-2026-55700", "record": "BREW-PNPM-CVE-2026-55700", "field": "published"}, {"timestamp": "2026-10-17T09:47:34Z", "date_only": false, "value": "2026-10-17T09:47:34Z", "kind": "other", "label": "Updated", "source": "osv_homebrew \u00b7 BREW-PNPM-CVE-2026-55700", "record": "BREW-PNPM-CVE-2026-55700", "field": "modified"}]}
