What is CVE-2026-15002?
CVE-2026-15002 is a high-severity cross-site scripting vulnerability in bluemediapl Autopay, published on 16 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
The Platnosci Online Blue Media (Autopay) plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 5.0.0 via the 'bm_woocommerce_css_editor_content' POST parameter. This is due to the Css_Editor::handle_save() method being wired to the WordPress 'init' hook by Settings_Manager::init_once() with no capability check, no nonce verification, and no sanitization on the input — the raw $_POST value is written to the 'woocommerce_bluemedia_settings' option via update_option(), then later echoed directly inside a <style> block on the WooCommerce checkout page by Css_Frontend::print_to_wp_head() with no output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page (the checkout page).
Weakness: CWE-79
