WordPress Plugin Vulnerabilities

FraudLabs Pro SMS Verification <= 1.12.1 - Unauthenticated Unrestricted SMS Sending via wp_sms_action_send

Description

The plugin does not enforce its SMS-retry limit on the server side, allowing unauthenticated users to send an unlimited number of verification SMS messages to attacker-chosen phone numbers, exhausting the site owner's paid SMS credits and spamming arbitrary third parties.
