CVE-2026-87918
UnknownSummary
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. This allows unauthenticated attackers to make those third-party API calls, and consume the associated cost, using the site's own configured API keys.
Risk Assessment
An unauthenticated attacker can use the site's API keys to generate costly AI provider requests, leading to unexpected charges and potential quota exhaustion. The financial risk is high.
Recommendation
Update the plugin to version 8.5.7 or later to fix the missing authorization and nonce checks.
