This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. Exploitation requires that the targeted form has a Text Area field configured with a 'url.<name>' Predefined Value and predefinedClick disabled, which is a documented and commonly used plugin feature.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N","score":4.7},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/calculated-fields-form/tags/5.5.1.2/js/fbuilder-pro-public.jquery.js#L1288","https://plugins.trac.wordpress.org/browser/calculated-fields-form/tags/5.5.1.2/js/fbuilder-pro-public.jquery.js#L692","https://plugins.trac.wordpress.org/browser/calculated-fields-form/tags/5.5.1.2/js/fields-public/05_fbuilder.ftextarea.js#L23","https://plugins.trac.wordpress.org/browser/calculated-fields-form/tags/5.5.1.2/js/modules/08_url/public/01_url.js#L140","https://plugins.trac.wordpress.org/changeset?reponame=&old=3713574%40calculated-fields-form&new=3713574%40calculated-fields-form"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:57:46.668721662+00:00"},"epss":{"cve":"CVE-2026-100184","score":0.00197,"percentile":0.09357,"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).
