{"cve":"CVE-2026-15155","nvd":{"published":"2026-07-11T07:16:46.170","modified":"2026-07-15T14:17:17.853","status":"Deferred","description":"The Essential Addons for Elementor – Popular Elementor Templates & Widgets plugin for WordPress is vulnerable to Authenticated Account Takeover via Email Header Injection in all versions up to, and including, 6.6.10 This is due to insufficient server-side validation of a Login/Register widget setting used to construct outgoing email headers — the allowed-values restriction is enforced only in the client-side editor UI and not on the server, and the applied sanitization does not strip or encode CR/LF characters, allowing CRLF sequences stored in that setting to survive into raw mail headers. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject an additional Bcc header into the WordPress administrator's password-reset notification email, receive a copy of a valid administrator password-reset link, and achieve full administrator account takeover.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-640"],"references":["https://plugins.trac.wordpress.org/browser/essential-addons-for-elementor-lite/tags/6.6.10/includes/Elements/Login_Register.php#L3333","https://plugins.trac.wordpress.org/browser/essential-addons-for-elementor-lite/tags/6.6.10/includes/Traits/Login_Registration.php#L1271","https://plugins.trac.wordpress.org/browser/essential-addons-for-elementor-lite/tags/6.6.10/includes/Traits/Login_Registration.php#L1622","https://plugins.trac.wordpress.org/browser/essential-addons-for-elementor-lite/tags/6.6.5/includes/Elements/Login_Register.php#L3333","https://plugins.trac.wordpress.org/browser/essential-addons-for-elementor-lite/tags/6.6.5/includes/Traits/Login_Registration.php#L1271"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:44:02.134301115+00:00"},"epss":{"cve":"CVE-2026-15155","score":0.00671,"percentile":0.52039,"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).
