Official description

GestSup versions up to and including 3.2.60 contain a cross-site request forgery (CSRF) vulnerability where the application does not verify the authenticity of client requests. An attacker can induce a logged-in user to submit crafted requests that perform actions with the victim's privileges. This can be exploited to create privileged accounts by targeting the administrative user creation endpoint.
