WordPress · Balbooa Forms · CVE-2026-67364
**Name of the Vulnerable Software and Affected Versions**
Balbooa Forms versions prior to 2.4.3.2
**Description**
An unauthenticated attacker can perform PHP code injection due to the use of the `eval()` function in the optional custom-PHP post-submission handler. The `[URL parameter = X]` shortcode is replaced with the raw, unescaped value of a query parameter, allowing arbitrary PHP code to execute on the server. Although a CSRF (Cross-Site Request Forgery) token is required to access the endpoint, it is disclosed anonymously through a separate task. This issue is exploitable if the form has a custom-PHP handler configured that references the shortcode and does not use reCAPTCHA on the submit button.
**Recommendations**
Update to version 2.4.3.2 or later.
As a temporary mitigation, disable the custom-PHP post-submission handler or implement reCAPTCHA on the submit button.
