Administrator-session script execution via unescaped profile name
Published Sep 9, 2026 · Updated Sep 9, 2026
Stored XSS in Themeum WP Crowdfunding 2.2.1 and earlier allows remote authenticated users to run scripts in an administrator's browser. The profile update path stores unsanitized first_name input, and the dashboard profile template outputs that value without escaping when show_user_id selects an account. Subscriber-level access is enough to plant the payload; execution occurs when an administrator opens the affected user's profile, exposing that WordPress session to attacker-controlled script actions.
