Unauthenticated Arbitrary File Deletion in Avada (Fusion) Builder <= 3.15.3
CVE-2026-8713 is a critical vulnerability in the Avada (Fusion) Builder plugin for WordPress affecting all versions up to and including 3.15.3. The flaw is caused by insufficient file path validation in the maybe_delete_files() function, which converts user-influenced upload URLs into filesystem paths and passes them to file deletion logic without securely resolving the path or enforcing containment within the intended upload directory. As a result, unauthenticated attackers can use path traversal sequences to cause deletion of arbitrary files on the server. Exploitation requires a published Avada form configured to save entries to the database. An attacker submits a crafted payload via the wp_ajax_nopriv_fusion_form_submit_ajax handler and controls the fusion_privacy_expiration_interval and privacy_expiration_action fields to force immediate cleanup, causing the malicious entry to be processed automatically by the Fusion_Form_DB_Privacy shutdown-hook routine without administrator interaction.
