The vulnerability stemmed from insufficient server-side validation in file upload handlers. The patch added beforeValidate() methods with UploadedFile::getInstance to enforce file type checks, indicating the original beforeSave methods in Article.php and User.php lacked these validations. Both methods called Util::handleModelSingleFileUpload which appears to have accepted any file type when combined with client-side bypass (e.g., modifying uploads via Burp). The CWE-434 classification and attacker reports of direct PHP uploads confirm this pattern.
