Submit #807559: FunAdmin v<=V7.1.0-rc6 Unrestricted Uploadinfo

TitleFunAdmin v<=V7.1.0-rc6 Unrestricted Upload
DescriptionFunAdmin through latest version (commit c4829f2, 2025-08-24) contains an unauthenticated arbitrary file upload vulnerability in the chunked upload endpoint /frontend/ajax/uploads. The chunkUpload() method in app/common/service/UploadService.php does not call the checkFile() security validation that is enforced in the regular upload flow, allowing an unauthenticated remote attacker to upload .php files to the web-accessible public/storage/uploads/ directory, resulting in Remote Code Execution (RCE). The frontend controller only applies the ViewNode middleware which performs no authentication checks.
