Administrator-driven element modification via missing nonce validation
Published Mar 27, 2024 · Updated Apr 28, 2026
CSRF in ThemeFusion Avada Builder 3.11.1 and earlier allows remote attackers to modify elements through forged requests. An undisclosed request handler omits or incorrectly performs WordPress nonce validation before modifying elements with third-party access tokens. The attack requires a logged-in administrator to click a malicious link or submit attacker-controlled content; Patchstack reports availability impact but does not identify the interrupting action.
