Authenticated action execution via unrestricted Dynamic Data

Published Apr 15, 2026 · Updated Apr 15, 2026

Code injection in ThemeFusion Avada Builder 3.15.1 and earlier allows remote authenticated users to invoke WordPress actions. The output_action_hook() function passes a Dynamic Data value to registered action hooks without checking authorization or restricting protected actions. Subscriber-level access is sufficient; consequences depend on installed hooks and include data exposure, privilege escalation, file inclusion, or service interruption.
