What the vulnerability does

01Description

The Starter Templates plugin for WordPress is vulnerable to arbitrary file upload in all versions up to, and including, 4.4.41. This is due to insufficient file type validation detecting WXR files, allowing double extension files to bypass sanitization while being accepted as a valid WXR file. This makes it possible for authenticated attackers, with author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

Explanation of Vulnerability in Simple Terms

02Summary

Starter Templates for Elementor & Gutenberg versions up to 4.4.41 contain an unrestricted file upload vulnerability. An authenticated user with low privileges can upload arbitrary files to the site without proper validation. This can lead to remote code execution, data theft, or site compromise. Update to a version newer than 4.4.41 immediately.
