This makes it possible for unauthenticated attackers to inject arbitrary additional email headers — such as `Bcc:` — into outgoing notification emails, silently blind-copying all notification email copies to an attacker-controlled address. Exploitation requires that a form notification is configured to use a Paragraph Text (textarea) field as the Reply-To display name via a Smart Tag.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-93"],"references":["https://plugins.trac.wordpress.org/browser/wpforms-lite/tags/1.10.0.2/includes/fields/class-textarea.php#L326","https://plugins.trac.wordpress.org/browser/wpforms-lite/tags/1.10.0.2/src/Emails/Mailer.php#L368","https://plugins.trac.wordpress.org/browser/wpforms-lite/tags/1.10.0.2/src/Emails/Notifications.php#L1098","https://plugins.trac.wordpress.org/browser/wpforms-lite/tags/1.10.0.2/src/Emails/Notifications.php#L1138","https://plugins.trac.wordpress.org/browser/wpforms-lite/tags/1.10.1.1/includes/fields/class-textarea.php#L326"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:42:16.820116992+00:00"},"epss":{"cve":"CVE-2026-12127","score":0.00595,"percentile":0.48467,"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).
