CVE-2026-45230Network attack vector

Unauthenticated file deletion via unchecked path joining

Published May 18, 2026 · Updated May 18, 2026

Path traversal in DumbWare DumbAssets 1.0.11 and earlier allows remote attackers to delete arbitrary files through file-deletion requests. The /api/delete-file endpoint and deleteAssetFileAsync() pass user-controlled paths to path.join() without checking that the result remains under the data directory. PIN authentication is optional and disabled by default, so network access is sufficient to delete files writable by the Node.js process and interrupt the service by removing critical application files.
