{"cve":"CVE-2026-15462","nvd":{"published":"2026-09-11T04:17:20.173","modified":"2026-09-11T15:16:59.660","status":"Deferred","description":"The Sticky Chat Widget plugin for WordPress is vulnerable to SQL Injection via the 'scw_form_fields' parameter array keys of the 'scw_save_form_data' AJAX action in versions up to, and including, 1.4.2. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-89"],"references":["https://plugins.trac.wordpress.org/browser/sticky-chat-widget/tags/1.4.2/includes/front-end.php#L141","https://plugins.trac.wordpress.org/browser/sticky-chat-widget/tags/1.4.2/includes/front-end.php#L188","https://plugins.trac.wordpress.org/browser/sticky-chat-widget/tags/1.4.2/includes/front-end.php#L60","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=","https://www.wordfence.com/threat-intel/vulnerabilities/id/35a49ba9-02a6-47cf-98f0-053b06036b08?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:53.108888569+00:00"},"epss":{"cve":"CVE-2026-15462","score":0.00505,"percentile":0.43185,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
