CVE-2021-34661Network attack vector

Log deletion via forged administrative request

Published Aug 9, 2021 · Updated May 23, 2025

Cross-site request forgery in Jack Arturo WP Fusion Lite 3.37.18 and earlier allows remote attackers to delete all plugin logs. The show_logs_section function in includes/admin/logging/class-log-handler.php accepts a forged administrative request and invokes its log-dropping path without validating request origin. Exploitation requires a logged-in user with access to the plugin logging interface to interact with attacker-controlled content; successful requests erase the complete plugin log history.
