• Compare installed versions against the affected version range in the advisory.
• Treat internet-facing systems as higher priority.
• Review logs for suspicious activity related to the affected application or component.

Technical summary

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.
