CVE-2026-6226: DynamiApps Frontend Admin privilege escalation via insecure form handling

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

Executive brief

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.
