Unauthenticated code execution via unchecked AJAX function dispatch
Published Jun 7, 2023 · Updated Apr 8, 2026
Function injection in 16 Epsilon Framework WordPress themes allows remote attackers to execute code through an unauthenticated AJAX request. The epsilon_framework_ajax_action handler dispatches attacker-selected functions without capability or CSRF nonce checks. An internet-reachable WordPress site with an affected theme installed is exposed to arbitrary function calls that can result in complete site takeover.
