CVE-2026-87918 Details
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.
A vulnerability exists in the WPBot WordPress plugin in versions prior to 8.5.7. The plugin fails to implement proper authorization or nonce checks on several AJAX actions that communicate with configured AI providers. This oversight allows unauthenticated attackers to make API calls to these third-party services, using the site's own API keys and incurring associated costs.
Users are advised to update the WPBot WordPress plugin to version 8.5.7 or later.
