Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

ApiAdmin v5.0 及更早版本存在目录遍历漏洞。在 ApiAdmin 中，管理员文件上传端点 POST /admin/Index/upload 直接使用上传文件的扩展名，未进行白名单、黑名单或内容检查，且 move_uploaded_file() 函数将文件保存到 Web 可访问的目录 public/upload/Ymd/ 中。任何已登录的管理员用户均可上传 .php 文件，并通过 HTTP 直接访问该文件，从而在服务器上实现远程代码执行。

Vulnerability Description
ApiAdmin v5.0 and before is vulnerable to Directory Traversal. The admin file-upload endpoint POST /admin/Index/upload in ApiAdmin takes the uploaded file's extension verbatim there is no whitelist, blacklist or content check and move_uploaded_file() drops the file into the web-accessible directory public/upload/Ymd/. Any logged-in admin user can upload a .php file and reach it directly over HTTP, achieving remote code execution on the server.
