AI-suggested

A fix is available in WPBot version 8.5.7 and later. Site administrators should upgrade to version 8.5.7 or newer to ensure proper authorization and nonce checks are enforced on AJAX actions. Until upgrading, restricting access to AJAX endpoints or disabling the plugin may reduce risk, but upgrading is the recommended remediation.

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.
