CVE-2026-102425: Balbooa Forms unauthenticated remote code execution via field shortcode injection

CVE-2026-102425 · Severity: info · Published 2026-09-29

Balbooa Forms is a Joomla extension for creating web forms with optional automated actions. The plugin allows administrators to configure PHP code to run after form submissions, but fails to properly sanitize form field references before executing this code. An attacker can submit a specially crafted form to inject arbitrary PHP code that executes with the web server's privileges, leading to complete site compromise.

Vendors: Balbooa.Com.

Technical details

The vulnerability exists in the form submission handler where field shortcodes are replaced with user-supplied values before the PHP code is passed to eval(). An unauthenticated attacker can exploit this by crafting a form submission containing a malicious payload in a field shortcode that is interpolated within a double-quoted PHP string in the configured post-submission action. No authentication or special configuration is required beyond a form using the PHP-after-submission feature with an attacker-controlled field reference.
