# CVE-2026-67364

> 10.0 CRITICAL

## Beschreibung

Joomla Extension - balbooa.com - Pre-auth PHP Code Injection in Balbooa Forms < 2.4.3.2 - CWE-94 / CWE-95 | CVSS 3.1: 9.8 Critical (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
The form's optional custom-PHP post-submission handler is executed via eval(). The [URL parameter = X] shortcode is substituted with the raw, unescaped value of a query parameter, letting an unauthenticated attacker inject arbitrary PHP that executes server-side. The CSRF token needed to reach the endpoint is itself disclosed anonymously via a separate task, so it provides no real protection. Exploitability requires the form to have a custom-PHP handler configured (a documented builder feature) referencing that shortcode, and no reCAPTCHA on the submit button.

## Schwachstellen-Klasse

- **CWE-94** — Improper Control of Generation of Code ('Code Injection')
  The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment.
- **CWE-95** — Improper Neutralization of Directives in Dynamically Evaluated Code ('Eval Injection')
  The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes code syntax before using the input in a dynamic evaluation call (e.g. "eval").
