{"id":"CVE-2026-18351","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-18351","summary":"The Drag and Drop File Upload for Elementor Forms plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.6.0 via the elementor_file_upload…","details":"The Drag and Drop File Upload for Elementor Forms plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.6.0 via the elementor_file_upload function. This is due to insufficient file type validation in the is_file_type_valid() function, which uses the attacker-controlled 'type' parameter as regex keys in the MIME allowlist, allowing blacklist bypass via a crafted extension that sanitize_file_name() later normalizes to a PHP extension. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible.","published":"2026-09-10T02:16:34.180","modified":"2026-09-10T02:16:34.180","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.svn.wordpress.org/drag-and-drop-file-upload-for-elementor-forms/tags/1.6.0/drag-and-drop-file-upload-for-elementor-forms.php"},{"type":"WEB","url":"https://plugins.svn.wordpress.org/drag-and-drop-file-upload-for-elementor-forms/tags/1.6.0/fields/file_upload.php"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/drag-and-drop-file-upload-for-elementor-forms/tags/1.6.0/fields/file_upload.php#L833"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset/3628051/drag-and-drop-file-upload-for-elementor-forms"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/03e853be-510f-4957-a227-17ca9f825b12?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T02:16:34.180"}}
