This makes it possible for authenticated attackers, with subscriber-level access and above, to update arbitrary options on the WordPress site. This can be leveraged to update the default role for registration to administrator and enable user registration for attackers to gain administrative user access.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-269"],"references":["https://github.com/etruel/wpematico/commit/e297f41b49c6ec76635b006dff8a964a99a1ed24","https://plugins.trac.wordpress.org/browser/wpematico/tags/2.8.23/app/tools_page.php#L224","https://plugins.trac.wordpress.org/browser/wpematico/tags/2.8.23/app/wpematico_functions.php#L2077","https://plugins.trac.wordpress.org/browser/wpematico/tags/2.8.23/app/wpematico_functions.php#L2096","https://plugins.trac.wordpress.org/browser/wpematico/tags/2.8.23/wpematico_class.php#L59"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-19883","score":0.00689,"percentile":0.52492,"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).
