## Technical details

The plugin fails to validate user capabilities before processing form submissions that write to global ACF options, allowing an unauthenticated attacker to submit arbitrary values via a publicly accessible form. The vulnerability exists in the form-submission action handler and requires no authentication, only the ability to interact with a public form. This broken access control (CWE-862) enables option overwriting on the affected site.
