CVE-2026-120513: Everest Forms <= 3.6.2 - Unauthenticated Arbitrary File Deletion via 'everest_forms_{form_id}_old_{field_id}' Parameter
The Everest Forms – Contact Form, Payment Form, Quiz, Survey & Custom Form Builder with AI plugin for WordPress is vulnerable to file deletion due to insufficient file path validation in the removecsvfileafteremailsend function in all versions up to, and including, 3.6.2 This makes it possible for unauthenticated attackers to delete files within the wp-content/uploads directory on the server, which can lead to loss of uploaded content. On hardened Apache configurations, deletion of uploads/.htaccess can re-enable PHP execution inside the uploads directory. This attack is only possible when the Save-and-Continue addon is active (EVFSAVEANDCONTINUEVERSION is defined) and the 'Disable storing entry information' setting is enabled on the target form. Escaping the uploads directory and deleting files in the site root can be possible under rare circumstances.
Event History
Frequently Asked Questions
Which sites are exposed to exploitation?
A site is exposed only if Everest Forms version 3.6.2 or earlier is installed, the Save-and-Continue addon is active, and the affected form has the “Disable storing entry information” setting enabled. The issue can be exploited without authentication.
What can an attacker delete?
An attacker can delete files in the server’s wp-content/uploads directory. In rare circumstances, path traversal may allow deletion of files in the site root.
What is the impact of deleting uploads/.htaccess?
On hardened Apache configurations, deleting uploads/.htaccess can re-enable PHP execution in the uploads directory. This may weaken a control intended to prevent execution of uploaded PHP files.
What can be done if an update cannot be applied immediately?
Disable the Save-and-Continue addon or disable the “Disable storing entry information” setting on affected forms. Either condition prevents the described attack path.
