CVE-2026-6226 · Severity: high · CVSS 8.8 · Published 2026-05-28

The Frontend Admin by DynamiApps plugin for WordPress, which allows users to edit content and manage profiles from the front end of a website, contains a security flaw that allows unauthorized users to gain administrative access. By submitting a specially crafted form, an attacker can bypass security checks to create a new account with full administrator privileges. This could lead to a complete takeover of the website, allowing attackers to steal data, modify content, or lock out legitimate owners.

## Technical details

The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to unauthenticated privilege escalation due to insecure handling of the '_acf_form' POST parameter. When this parameter is provided as an array instead of a form ID, the 'validate_form()' function bypasses database lookups and processes the attacker-supplied structure directly. This allows an attacker to inject a custom form configuration where the 'role_options' field is set to 'administrator'. Because the 'pre_update_value()' validation logic reads from this attacker-controlled definition, the security check is bypassed, enabling the creation of administrator accounts. The vulnerability is present in versions up to and including 3.29.2.
