CVE-2024-4180Public exploitNetwork attack vector

Reflected XSS via unsanitized AJAX view data

Published Jun 4, 2024 · Updated Mar 18, 2025

Reflected XSS in The Events Calendar before 6.4.0.1 allows remote attackers to execute script through an unauthenticated AJAX request. The tribe_events_views_v2_fallback action passes attacker-controlled nested view_data values into AJAX-rendered output without adequate sanitization. Loading an attacker-controlled form is the gate; successful reflection executes script in the WordPress site's browser origin, enabling page-data access or same-origin actions as that visitor.
