CVE-2026-4782Network attack vector

Authenticated file read via unrestricted shortcode path

Published May 13, 2026 · Updated May 13, 2026

Absolute path traversal in ThemeFusion Avada Builder 3.15.2 and earlier allows remote authenticated users to read server files. The fusion_get_svg_from_file function treats the custom_svg value from the fusion_section_separator shortcode as a file path without restricting it to trusted SVG locations. Subscriber-level access is sufficient, and exposed files can contain credentials or other sensitive server data; no write or execution impact is reported.
