Because `display_name` is writable by any user on their own account through the core profile form, this makes it possible for authenticated attackers with Subscriber-level access and above to execute arbitrary shortcodes. Where the page is a users collection — an ordinary team or member-directory page — the shortcode runs in the request of every visitor, including unauthenticated ones. Requires a published page with a Kirki element whose dynamic content is bound to the `display_name` user field.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","score":5.4},"cwes":["CWE-74"],"references":["https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.1/includes/Frontend/Preview/Utils.php#L308","https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.1/includes/Frontend/Preview/Utils.php#L334","https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.1/includes/Frontend/Preview/Utils.php#L408","https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.1/includes/Frontend/TheFrontend.php#L144","https://plugins.trac.wordpress.org/browser/kirki/tags/6.3.1/includes/HelperFunctions.php#L1117"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-102291","score":0.00304,"percentile":0.22962,"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).
