Typically, an application should restrict the types of <a href=\"https:\/\/www.ameeba.com\/blog\/cve-2025-39401-unrestricted-file-upload-leading-to-potential-system-compromise-in-mojoomla-wpams\/\"  data-wpil-monitor-id=\"52045\">files that can be uploaded<\/a> to prevent the upload of malicious files such as a web shell.
