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*", "creation_timestamp": "2026-06-27T07:12:30.944402Z"} 2026-06-27T07:12:30.944402+00:00 https://vulnerability.circl.lu/sighting/e0f02ff6-5370-4e48-89a8-f81fccfec8a5/export 2026-07-01T08:20:03.806150+00:00 Automation user https://vulnerability.circl.lu/user/automation {"uuid": "e0f02ff6-5370-4e48-89a8-f81fccfec8a5", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2026-55700", "type": "seen", "source": "https://bsky.app/profile/cve.skyfleet.blue/post/3mp4zjp5xqs2o", "content": "CVE-2026-55700 - pnpm: stage download writes outside destination via manifest version traversal\nCVE ID : CVE-2026-55700\n \n Published : June 25, 2026, 4:47 p.m. | 57\u00a0minutes ago\n \n Description : pnpm is a package manager.
