This is due to missing or incorrect nonce validation on the dismiss_notice function called via the admin_action_ucp_dismiss_notice action. This makes it possible for unauthenticated attackers to dismiss plugin notifications via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.","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/under-construction-page/trunk/under-construction.php?rev=2848705#L901","https://www.wordfence.com/threat-intel/vulnerabilities/id/031a1203-6b0d-453b-be8a-12e7f55cb401?source=cve","https://plugins.trac.wordpress.org/browser/under-construction-page/trunk/under-construction.php?rev=2848705#L901","https://www.wordfence.com/threat-intel/vulnerabilities/id/031a1203-6b0d-453b-be8a-12e7f55cb401?source=cve"],"products":["webfactoryltd:under_construction"],"source":"nvd","synced_at":"2026-10-19T21:38:24.161619714+00:00"},"epss":{"cve":"CVE-2023-0831","score":0.00247,"percentile":0.161,"date":"2026-11-01"},"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).
