CVE-2025-63695Public exploitNetwork attack vector

Unauthenticated active-content upload via UEditor controller

Published Nov 18, 2025 · Updated Nov 19, 2025

Arbitrary file upload in DzzOffice 2.3.7 and earlier allows remote attackers to store active web content through the UEditor endpoint. Its getFilePath logic joins the configured pathFormat to DOCUMENT_ROOT, while the default allowlist accepts HTML, JavaScript, and CSS files. The controller lacks an entry-point authorization guard, so no login is required to place browser-executable content under the web root and enable persistent cross-site scripting.
