CVE-2026-96561 · Severity: high · CVSS 7.2 · Published 2026-10-01

The AI Engine plugin for WordPress, which adds chatbot and AI framework capabilities to WordPress sites, is vulnerable to Stored Cross-Site Scripting (XSS).

Technical details

The vulnerability is a chain of flaws: inadequate input filtering on the /mwai-ui/v1/chats/submit REST endpoint allows attackers to bypass a denylist via key canonicalization (model_ → model), write attacker-controlled strings to the PHP error log unescaped, and subsequently retrieve that log content through the plugin's error parser and Advisor task, which injects it into AI prompts and stores the unsanitized response in the database. The Advisor dashboard widget then renders this stored content without HTML escaping, creating a Stored XSS vulnerability accessible to any authenticated WordPress administrator viewing the dashboard.
