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.","publishedAt":"2026-07-11T05:35:49.683Z","updatedAt":"2026-07-15T13:46:28.209Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["wpdevteam Essential Addons for Elementor – Popular Elementor Templates & Widgets"],"affected":[{"vendor":"wpdevteam","product":"Essential Addons for Elementor – Popular Elementor Templates & Widgets","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"6.6.10","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/cbe8cf6c-b1fa-4f71-bb63-c8b181e54882?source=cve","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/6.6.10/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","https://plugins.trac.wordpress.org/browser/essential-addons-for-elementor-lite/tags/6.6.5/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/changeset/3601504/essential-addons-for-elementor-lite/trunk/includes/Traits/Login_Registration.php","https://plugins.trac.wordpress.org/changeset?old_path=%2Fessential-addons-for-elementor-lite/tags/6.6.10&new_path=%2Fessential-addons-for-elementor-lite/tags/6.6.11"],"weaknesses":["CWE-640"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15155.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15155","state":"PUBLISHED","datePublished":"2026-07-11T05:35:49.683Z","dateUpdated":"2026-07-15T13:46:28.209Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-08T19:50:24.698Z"},"containers":{"cna":{"title":"Essential Addons for Elementor <= 6.6.10 - Authenticated (Contributor+) Account Takeover via Email Header Injection","descriptions":[{"lang":"en","value":"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.
