## What is CVE-2026-6226?

CVE-2026-6226 is a high-severity vulnerability in shabti Frontend Admin by DynamiApps, published on 28 May 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

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.

Weakness: CWE-269 (Improper Privilege Management)

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
