This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to create a new administrator-level user account and achieve full site takeover by saving and executing a malicious workflow containing a wp_create_user action node specifying role=administrator. This vulnerability is exploitable by unauthenticated attackers on any site where the [aiwu-form] shortcode or public chatbot is rendered on a frontend page, as the waic-nonce value is emitted into publicly accessible JavaScript (WAIC_DATA.waicNonce) on those pages, rendering the nonce check a non-functional authorization barrier.","published":"2026-08-08T07:17:08.297","modified":"2026-08-12T21:00:52.257","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":{"score":0.00669,"percentile":0.49957,"asOf":"2026-09-12"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/ai-copilot-content-generator/tags/1.5.4/classes/assets.php#L96"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/ai-copilot-content-generator/tags/1.5.4/classes/frame.php#L211"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/ai-copilot-content-generator/tags/1.5.4/modules/forms/views/forms.php#L87"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/ai-copilot-content-generator/tags/1.5.4/modules/workflow/blocks/actions/wp_create_user.php#L107"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/ai-copilot-content-generator/tags/1.5.4/modules/workflow/controller.php#L39"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/ai-copilot-content-generator/tags/1.5.4/modules/workflow/controller.php#L86"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/ai-copilot-content-generator/tags/1.5.6/classes/assets.php#L96"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/ai-copilot-content-generator/tags/1.5.6/classes/frame.php#L211"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/ai-copilot-content-generator/tags/1.5.6/modules/forms/views/forms.php#L87"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/ai-copilot-content-generator/tags/1.5.6/modules/workflow/blocks/actions/wp_create_user.php#L107"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/ai-copilot-content-generator/tags/1.5.6/modules/workflow/controller.php#L39"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/ai-copilot-content-generator/tags/1.5.6/modules/workflow/controller.php#L86"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/e28ae1a3-abc6-484c-abc7-1e0b958fa30b?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T21:00:52.257"}}
