Understanding the Critical Threat to Balbooa Forms
A severe security flaw has been uncovered in Balbooa Forms, a popular extension for Joomla websites. This vulnerability, identified as CVE-2026-102425, allows attackers to execute malicious code on affected websites without needing to log in. This type of attack is known as Unauthenticated Remote Code Execution (RCE) and poses a critical risk to the integrity and security of your website.
The core of this issue lies within how Balbooa Forms handles PHP code defined by administrators for post-submission actions. Specifically, when a public form is set up to run custom PHP code and includes form-field shortcodes, the component improperly replaces these shortcodes with raw user-submitted values before executing the PHP. This oversight creates an opening for an attacker to inject harmful code, leading to complete control over the compromised server.
