CVE-2026-1541Network attack vector

Subscriber-level metadata disclosure via unchecked protected keys

Published Apr 15, 2026 · Updated Apr 15, 2026

Information disclosure in ThemeFusion Avada Builder 3.15.1 and earlier allows remote authenticated users to read protected post metadata. fusion_get_post_custom_field() accepts the Dynamic Data post_custom_field parameter without rejecting underscore-prefixed protected metadata keys. Subscriber-level access is sufficient, and the flaw exposes protected metadata without allowing post modification or service interruption.
