A serious security flaw has been found in Balbooa Forms, a popular extension for Joomla websites. This vulnerability, identified as CVE-2026-101127, could allow an attacker to inject malicious code into your website, posing a significant risk, especially to administrators.
This particular issue is a ‘Stored Cross-Site Scripting’ (XSS) vulnerability. In simple terms, it means an attacker can upload a file with a specially crafted, harmful filename. Even though the system checks the file type, it doesn’t properly clean up or ‘sanitize’ this filename when it’s stored in the database. Later, when a website administrator views a form submission that includes this malicious file, the harmful filename is displayed in a way that triggers the injected code. This code then runs in the administrator’s browser, potentially allowing the attacker to steal sensitive information, deface the website, or take control of the administrator’s session. The fact that an attacker doesn’t need to be logged in to exploit this makes it particularly dangerous.
