Technical details
The plugin fails to validate CSRF tokens or verify request origin on two administrative actions that bulk-delete captured form submissions and reset form statistics. An attacker exploits this via cross-site request forgery by crafting a forged request and tricking an authenticated administrator into triggering it, resulting in irreversible data destruction.
