This is due to missing nonce validation on the plugin's settings form in the dxuc-unanswered-comments-admin-page.php file. This makes it possible for unauthenticated attackers to modify plugin settings (dxuc_authors_list and dxuc_comment_count) 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/dx-unanswered-comments/tags/1.7/dxuc-unanswered-comments-admin-page.php#L13","https://plugins.trac.wordpress.org/browser/dx-unanswered-comments/tags/1.7/dxuc-unanswered-comments-admin-page.php#L21","https://plugins.trac.wordpress.org/browser/dx-unanswered-comments/tags/1.7/dxuc-unanswered-comments-admin-page.php#L25","https://plugins.trac.wordpress.org/browser/dx-unanswered-comments/tags/1.7/dxuc-unanswered-comments-admin-page.php#L40","https://plugins.trac.wordpress.org/browser/dx-unanswered-comments/trunk/dxuc-unanswered-comments-admin-page.php#L13"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:30:49.762551342+00:00"},"epss":{"cve":"CVE-2026-4138","score":0.00193,"percentile":0.09045,"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).
