Description
The My Calendar plugin for WordPress is vulnerable to Path Traversal in versions up to, and including, 2.3.29 via the 'edit_my_calendar_styles' function in the 'my-calendar-styles.php' file. This allows unauthenticated attackers to overwrite the contents of all files the vulnerable service has access to, including adding executable PHP to PHP files.
