CVE-2026-6226 | Frontend Admin by DynamiApps <= 3.29.2 - Unauthenticated Privilege Escalation via Form Configuration Injection

The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to unauthenticated privilege escalation in versions up to and including 3.29.2. This is due to insecure form submission handling that accepts arbitrary form definitions from user input instead of securely loading them from the backend. When $_POST['_acf_form'] is an array (rather than a form ID), the validate_form() function bypasses database lookup and directly processes the attacker-controlled structure. The create_record() function preserves attacker-supplied record data if present, and the user action's run() function falls back to attacker-controlled field definitions from $form['fields'] when legitimate fields cannot be found. The role field's pre_update_value() validation reads $field['role_options'] from this attacker-controlled definition, allowing an attacker to specify ['administrator'] as an allowed role and bypass the security check. This makes it possible for unauthenticated attackers to create administrator accounts by injecting a custom form configuration with a spoofed role field.

8.8 3.1 HIGH
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
