Technical details

The MapSVG plugin for WordPress suffers from an arbitrary file upload vulnerability within the SVGFile constructor. The root cause is an incorrect conditional check that inadvertently bypasses file type validation routines. This flaw allows authenticated attackers with Administrator-level privileges to upload arbitrary files, including PHP scripts, to the web server. Successful exploitation can lead to Remote Code Execution (RCE). The vulnerability is present in all versions up to 8.14.0 and was addressed in version 8.14.1.
