CVE-2015-10093Network attack vector

Admin-page markup corruption via unescaped URL

Published Mar 6, 2023 · Updated Aug 6, 2024

Reported reflected XSS in Mark User as Spammer 1.0.0 and 1.0.1 allows remote authenticated users to alter an admin page via a crafted URL. The user_row_actions function in plugin/plugin.php passes the request-derived URL through site_url() and writes it into a link href without esc_url(). The administrator must open the crafted users.php URL; the upstream maintainer states that wp_nonce_url() prevents script execution and only page markup is corrupted.
