Subscriber-level stored XSS via unsanitized settings
Published Oct 31, 2023 · Updated Apr 23, 2025
Stored XSS in WP Meta and Date Remover before 2.2.0 allows remote authenticated users to execute script in visitors' browsers. The update_settings AJAX action accepts subscriber-supplied cssCode without a capability check or sanitization and later renders it unescaped. Subscriber access is sufficient; the stored payload runs on front-end and administrative pages viewed by other users, exposing their WordPress session context.
