Super Forms <= 6.3.316 - Unauthenticated Path Traversal to Arbitrary File Read via 'sfgtfi' URL Path Parameter

9.1
Path Traversal: '/dir/../filename'
CVE CVE-2026-15896
CVSS 9.1 (Critical)
Publicly Published October 1, 2026
Last Updated October 2, 2026

Description

The Super Forms – Drag & Drop Form Builder plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 6.3.316 via the parse_request function. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. The optional 'file_upload_auth' setting defaults to empty, meaning no authentication is required in the default configuration; enabling this setting mitigates unauthenticated exploitation but does not remediate the path traversal itself. Exploitation on Linux requires a real 13-digit timestamp directory to exist, whereas on Windows the traversal works with any hardcoded 13-digit prefix. However, the plugin's file upload response returns the name of the created directory, which means the vulnerability is exploitable as long as file upload is enabled on the form.
