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 injected payload is stored in the registering user's 'submitted' usermeta via update_user_meta() and is only triggered when an administrator opens the affected user record in the wp-admin Users modal, which inserts the unescaped output via jQuery .html().","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://github.com/ultimatemember/ultimatemember/releases/tag/2.14.0","https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.13.1/includes/admin/core/class-admin-builder.php#L1090","https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.13.1/includes/core/class-form.php#L422","https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.13.1/includes/core/class-form.php#L768","https://plugins.trac.wordpress.org/browser/ultimate-member/tags/2.13.1/includes/core/class-user.php#L1447"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-96270","score":0.00247,"percentile":0.15807,"date":"2026-10-25"},"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).
