{"cve":"CVE-2026-6400","nvd":{"published":"2026-05-20T02:16:38.067","modified":"2026-07-24T08:10:00.150","status":"Deferred","description":"The Child Height Predictor by Ostheimer plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to and including 1.3. This is due to missing nonce verification in the options() function, which handles plugin settings updates. The form template does not include a wp_nonce_field() call, and the handler never calls check_admin_referer() or wp_verify_nonce(). This makes it possible for unauthenticated attackers to trick a site administrator into clicking a link or visiting a malicious page that submits a forged POST request, causing unauthorized changes to the plugin settings such as unit preferences to be persisted to the database via update_option().","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","score":4.3},"cwes":["CWE-352"],"references":["https://plugins.trac.wordpress.org/browser/child-height-predictor/tags/1.3/childheight.php#L135","https://plugins.trac.wordpress.org/browser/child-height-predictor/tags/1.3/childheight.php#L149","https://plugins.trac.wordpress.org/browser/child-height-predictor/trunk/childheight.php#L135","https://plugins.trac.wordpress.org/browser/child-height-predictor/trunk/childheight.php#L149","https://www.wordfence.com/threat-intel/vulnerabilities/id/dc1681a8-5f2e-45f1-96d9-797b13644607?source=cve"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-6400","score":0.00163,"percentile":0.05489,"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).
