{"id":"CVE-2026-115483","published":"2026-11-10T20:18:03.537","lastModified":"2026-11-10T20:18:03.703","description":"The Everest Forms plugin for WordPress is vulnerable to Arbitrary File Read in all versions up to, and including, 3.6.3 via the attach_entry_files() function. 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.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-22"],"vendors":[],"products":[],"references":[{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1637","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1645","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1717","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1727","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1728","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1735","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1793","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1816","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1824","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/class-evf-form-task.php#L1504","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/evf-core-functions.php#L1249","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/evf-entry-functions.php#L22","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/evf-entry-functions.php#L58","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset/3786305/everest-forms","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/03f636e6-271d-4516-8db1-dc268ff794e7?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
