RCE in Balbooa.com Balbooa Forms Extension For Joomla

CVE-2026-102425

Joomla Extension - balbooa.com - Unauthenticated RCE via field shortcode injection in Balbooa Forms < 2.4.3.4 - Balbooa Forms supports administrator-defined PHP code which runs after a public form submission. The feature also supports form-field shortcodes inside that PHP. Before calling `eval()`, the component replaces each shortcode with the raw value submitted by the visitor, leading to an RCE vector. A public form must use the product's optional PHP-after-submission action and interpolate an attacker-controlled field shortcode inside a double-quoted PHP string to be vulnerable.

Vulnerability class: RCE (Remote Code Execution)
