{"cve":"CVE-2026-3362","nvd":{"published":"2026-04-22T09:16:21.757","modified":"2026-06-17T10:43:28.503","status":"Deferred","description":"The Short Comment Filter plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Minimum Count' settings field in all versions up to and including 2.2. This is due to insufficient input sanitization (no sanitize callback on register_setting) and missing output escaping (no esc_attr() on the echoed value in the input's value attribute). The option value is stored via update_option() and rendered unescaped in an HTML attribute context. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in the settings page that will execute whenever a user accesses that page. This is particularly impactful in WordPress multisite installations or when DISALLOW_UNFILTERED_HTML is set, where administrators are not granted the unfiltered_html capability.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N","score":4.4},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/short-comment-filter/tags/2.2/classes/short-comment-filter-settings.php#L21","https://plugins.trac.wordpress.org/browser/short-comment-filter/tags/2.2/classes/short-comment-filter-settings.php#L54","https://plugins.trac.wordpress.org/browser/short-comment-filter/tags/2.2/classes/short-comment-filter-settings.php#L61","https://plugins.trac.wordpress.org/browser/short-comment-filter/tags/2.2/views/settings.php#L25","https://plugins.trac.wordpress.org/browser/short-comment-filter/trunk/classes/short-comment-filter-settings.php#L21"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:30:49.762551342+00:00"},"epss":{"cve":"CVE-2026-3362","score":0.00373,"percentile":0.3122,"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).
