This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The wp_kses() output filtering pass provides no mitigation because NEXForms_allowed_tags() explicitly permits <script>, <iframe src/srcdoc>, and JS event handlers such as onClick, onBlur, and onChange in its allow-list.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N","score":7.2},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/nex-forms-express-wp-form-builder/tags/9.1.10/includes/classes/class.db.php#L2660","https://plugins.trac.wordpress.org/browser/nex-forms-express-wp-form-builder/tags/9.1.10/includes/classes/class.db.php#L2809","https://plugins.trac.wordpress.org/browser/nex-forms-express-wp-form-builder/tags/9.1.10/includes/classes/class.functions.php#L2343","https://plugins.trac.wordpress.org/browser/nex-forms-express-wp-form-builder/tags/9.1.10/main.php#L2660","https://plugins.trac.wordpress.org/browser/nex-forms-express-wp-form-builder/tags/9.1.10/main.php#L2720"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:42:16.820116992+00:00"},"epss":{"cve":"CVE-2026-12142","score":0.00527,"percentile":0.44674,"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).
