The AI Copilot - Content Generator plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.5.6. 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.

AnalysisAI
Unauthenticated privilege escalation to full site takeover in the AI Copilot - Content Generator plugin for WordPress (all versions through 1.5.6) lets remote attackers create an administrator account by saving and executing a malicious workflow whose wp_create_user action node specifies role=administrator. The plugin's only authorization barrier is a waic-nonce that is publicly emitted into frontend JavaScript (WAIC_DATA.waicNonce) on any page rendering the [aiwu-form] shortcode or public chatbot, so the nonce check provides no real protection. Reported by Wordfence with CVSS 9.8; no public exploit identified at time of analysis, but exploitation is trivial once the shortcode or chatbot is on a public page.
Technical ContextAI
The affected software is a WordPress plugin (CPE cpe:2.3:a:wupsales:ai_copilot_-_content_generator) providing AI-driven content generation, front-end forms via the [aiwu-form] shortcode, and a chatbot backed by a 'workflow' engine with pluggable action nodes. The root cause is CWE-269 (Improper Privilege Management): the workflow controller (modules/workflow/controller.php around lines 39 and 86) gates save/execute operations only on a WordPress nonce, and the wp_create_user action node (modules/workflow/blocks/actions/wp_create_user.php line 107) assigns any requested role, including administrator, without verifying the requester's capabilities. Because assets.php (line 96) and frame.php (line 211) print the waic-nonce into a publicly readable WAIC_DATA.waicNonce JavaScript object whenever the form/chatbot renders on the frontend, the nonce is not secret and cannot serve as an authorization control - WordPress nonces are CSRF/replay mitigations, not capability checks, and are misused here as the sole authorization gate.
RemediationAI
No fixed version was provided in the source data, so no vendor-released patch is identified at time of analysis - monitor the Wordfence advisory (https://www.wordfence.com/threat-intel/vulnerabilities/id/e28ae1a3-abc6-484c-abc7-1e0b958fa30b?source=cve) and the plugin changelog for a release above 1.5.6 and upgrade immediately when available. As the most effective compensating control, deactivate and remove the AI Copilot - Content Generator plugin until a patched version ships, since the vulnerability is in shipped code. If it cannot be removed, remove the [aiwu-form] shortcode and any public chatbot from all frontend pages so the waic-nonce is no longer emitted publicly and the workflow endpoint is not reachable unauthenticated (trade-off: this disables the plugin's public form/chatbot functionality). Additionally, apply a WAF rule to block requests to the workflow save/execute controller endpoints and request bodies containing wp_create_user or role=administrator, and audit wp_users for unexpected recently created administrator accounts, revoking any unrecognized ones (trade-off: WAF signatures can be bypassed and are a stopgap, not a fix).
