{"id":"CVE-2026-0673","state":"PUBLISHED","title":"Element Pack Addons for Elementor <= 8.3.15 - Unauthenticated SMTP Header Injection","description":"The Element Pack Addons for Elementor plugin for WordPress is vulnerable to Email Header Injection in all versions up to, and including, 8.3.15 via the `element_pack_contact_form` AJAX action. This is due to insufficient sanitization of newline characters in user-supplied input that gets concatenated into email headers. This makes it possible for unauthenticated attackers to inject arbitrary email headers into emails sent by the contact form.","publishedAt":"2026-08-06T12:27:39.294Z","updatedAt":"2026-08-06T14:05:57.732Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["bdthemes Element Pack Addons for Elementor – Elementor Widgets, Elementor Templates, Elementor Addons"],"affected":[{"vendor":"bdthemes","product":"Element Pack Addons for Elementor – Elementor Widgets, Elementor Templates, Elementor Addons","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"8.3.15","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/941d0647-5027-4642-88fc-3ab26acbb639?source=cve","https://plugins.trac.wordpress.org/browser/bdthemes-element-pack-lite/tags/8.3.16/modules/contact-form/module.php?marks=209#L209"],"weaknesses":["CWE-93"],"ingestedAt":"2026-10-29T20:10:13.529Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/0xxx/CVE-2026-0673.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-0673","state":"PUBLISHED","datePublished":"2026-08-06T12:27:39.294Z","dateUpdated":"2026-08-06T14:05:57.732Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-01-07T17:15:14.569Z"},"containers":{"cna":{"title":"Element Pack Addons for Elementor <= 8.3.15 - Unauthenticated SMTP Header Injection","descriptions":[{"lang":"en","value":"The Element Pack Addons for Elementor plugin for WordPress is vulnerable to Email Header Injection in all versions up to, and including, 8.3.15 via the `element_pack_contact_form` AJAX action.
