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 \u201cAttach Files\u201d setting enabled and that contains a field with a meta key matching /signature_/ (for example, a text field labelled \u201cSignature\u201d), 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."}], "title": "Everest Forms <= 3.6.3 - Unauthenticated Arbitrary File Read via 'Signature' Field Meta Key Branch of attach_entry_files", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/03f636e6-271d-4516-8db1-dc268ff794e7?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1727"}, {"url": "https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1728"}, {"url": "https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1735"}, {"url": "https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1793"}, {"url": "https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1816"}, {"url": "https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1824"}, {"url": "https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1637"}, {"url": "https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1645"}, {"url": "https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1717"}, {"url": "https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/evf-entry-functions.php#L58"}, {"url": "https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/evf-entry-functions.php#L22"}, {"url": "https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/evf-core-functions.php#L1249"}, {"url": "https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/class-evf-form-task.php#L1504"}, {"url": "https://plugins.trac.wordpress.org/changeset/3786305/everest-forms"}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-22 Improper Limitation of a Pathname to a Restricted Directory", "cweId": "CWE-22", "type": "CWE"}]}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N", "baseScore": 7.5, "baseSeverity": "HIGH"}}], "credits": [{"lang": "en", "type": "finder", "value": "Maciej Komorowski"}], "timeline": [{"time": "2026-10-22T15:28:25.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-11-10T06:49:17.000Z", "lang": "en", "value": "Disclosed"}]}}}
