Technical details
The vulnerability is a Cross-Site Request Forgery (CSRF) flaw in Hash Form plugin versions 1.4.0 and earlier. The plugin fails to properly validate or protect against cross-site requests, allowing an attacker to forge requests that execute actions on behalf of authenticated administrators. Attack requires user interaction: a logged-in admin must be tricked into visiting an attacker-controlled page. An attacker can modify form configurations, settings, or other admin-level functionality without the user's consent. The vulnerability is patched in version 1.4.1 and later.
