Technical details
The Avada Builder plugin for WordPress is vulnerable to an arbitrary file read vulnerability (path traversal) due to insufficient input validation in the 'fusion_get_svg_from_file' function. Specifically, the 'custom_svg' parameter within the 'fusion_section_separator' shortcode does not properly sanitize file paths. An authenticated attacker with Subscriber-level permissions or higher can exploit this to retrieve the contents of arbitrary files on the server, such as wp-config.php. The issue was partially addressed in version 3.15.2 and fully resolved in version 3.15.3.
