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."}],"affected":[{"source":"security@wordfence.com","affectedData":[{"vendor":"wpeverest","product":"Everest Forms – Contact Form, Payment Form, Quiz, Survey \u0026 Custom Form Builder with AI","defaultStatus":"unaffected","versions":[{"version":"0","lessThanOrEqual":"3.6.3","versionType":"semver","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security@wordfence.com","type":"Primary","cvssData":{"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","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":3.6}]},"weaknesses":[{"source":"security@wordfence.com","type":"Primary","description":[{"lang":"en","value":"CWE-22"}]}],"references":[{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1637","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1645","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1717","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1727","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1728","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1735","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1793","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1816","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/abstracts/class-evf-form-fields-upload.php#L1824","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/class-evf-form-task.php#L1504","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/evf-core-functions.php#L1249","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/evf-entry-functions.php#L22","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/tags/3.6.3/includes/evf-entry-functions.php#L58","source":"security@wordfence.com"},{"url":"https://plugins.trac.wordpress.org/changeset/3786305/everest-forms","source":"security@wordfence.com"},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/03f636e6-271d-4516-8db1-dc268ff794e7?source=cve","source":"security@wordfence.com"}]}}
