Unauthenticated stored XSS via unsanitized CSS setting
Published Aug 16, 2026 · Updated Aug 16, 2026
Stored XSS in Autopay 5.0.0 and earlier allows remote attackers to execute scripts in checkout visitors' browsers via a crafted POST request. Css_Editor::handle_save() accepts the raw bm_woocommerce_css_editor_content value without authorization, nonce validation, or sanitization, stores it in woocommerce_bluemedia_settings, and Css_Frontend::print_to_wp_head() emits it unescaped inside a style block. No account is required; successful exploitation persists attacker-controlled script that runs for any user who opens the affected checkout page.
