Path Traversal in Themefusion Avada (Fusion) Builder

CVE-2026-4782

The Avada Builder plugin for WordPress is vulnerable to Arbitrary File Read in all versions up to, and including, 3.15.2 via the 'fusion_get_svg_from_file' function with the 'custom_svg' parameter of the 'fusion_section_separator' shortcode. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information. The vulnerability was partially patched in version 3.15.2 and fully patched in version 3.15.3.
