This is due to the function attaching any entry field value whose meta key matches /signature_/ to the notification email after only a file_exists() check, without validating or restricting the path. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, such as wp-config.php, which can contain sensitive information. Successful exploitation requires a form whose email notification has the “Attach Files” setting enabled and that contains a field with a meta key matching /signature_/ (for example, a text field labelled “Signature”), with the notification routed to an attacker-supplied email address so the exfiltrated file is delivered to the attacker. Note: The Everest Forms Pro add-on is required to exploit this vulnerability, as it provides the signature field and the email file-attachment functionality (file-email-attachments) that the attack relies on.","published":"2026-11-10T20:18:03.537","modified":"2026-11-10T20:18:03.703","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1637"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1645"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1717"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1727"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1728"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1735"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1793"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1816"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1824"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/class-evf-form-task.php#L1504"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/evf-core-functions.php#L1249"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/evf-entry-functions.php#L22"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/evf-entry-functions.php#L58"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset/3786305/everest-forms"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/03f636e6-271d-4516-8db1-dc268ff794e7?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-11-10T20:18:03.703"}}
