This is due to the save_form_data() function passing attacker-controlled POST array keys unsanitized to $wpdb->insert(), which wraps column identifiers in backticks without escaping them, allowing a backtick in an attacker-supplied key to break out of the column-identifier list into raw SQL; additionally, the use of filter_input() bypasses WordPress's wp_magic_quotes() protection, and the widget_id validation loop is skipped entirely when no valid widget_id is supplied, leaving $isValid at 1. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.","published":"2026-09-11T04:17:20.173","modified":"2026-09-11T04:17:20.173","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/sticky-chat-widget/tags/1.4.2/includes/front-end.php#L141"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/sticky-chat-widget/tags/1.4.2/includes/front-end.php#L188"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/sticky-chat-widget/tags/1.4.2/includes/front-end.php#L60"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&new=3640407%40sticky-chat-widget%2Ftrunk%2Fincludes%2Ffront-end.php&old=3349742%40sticky-chat-widget%2Ftrunk%2Fincludes%2Ffront-end.php&sfp_email=&sfph_mail="},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/35a49ba9-02a6-47cf-98f0-053b06036b08?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-11T04:17:20.173"}}
