WPBot < 8.5.7 - Unauthenticated AI Provider API Abuse via Multiple AJAX Actions

Published Sep 12, 2026 · Updated Sep 12, 2026 · Assigned by WPScan

Description

The WPBot WordPress plugin before 8.5.7 does not perform any authorization or nonce check on several AJAX actions that relay prompts to its configured AI providers, allowing unauthenticated attackers to make those third-party API calls, and consume the associated cost, using the site's own configured API keys.
