MITRE ATT&CK
1 technique across 1 tactic: Privilege Escalation The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | The WordPress site must have the AI Copilot - Content Generator plugin installed and activated in versions 1.4.12 or earlier. No authentication is required - the vulnerable actions are registered under wp_ajax_nopriv_ hooks, explicitly making them accessible to unauthenticated visitors. No special server configuration or non-default plugin settings are needed beyond the plugin being active. The CVSS vector AV:N/AC:L/PR:N/UI:N confirms no special conditions limit remote unauthenticated exploitation against default plugin configurations. Exploitation is limited in scope to deletion of plugin-managed database table records - there is no confirmed path to confidentiality breach, privilege escalation, or remote code execution. The attack surface is further bounded by the plugin's install footprint: only sites with this specific plugin active are vulnerable. |
| Impact | The NVD-assigned CVSS 5.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N) understates the integrity impact: the description explicitly allows deletion of ALL records from any module's database table, not merely specific limited modifications - this warrants I:H rather than I:L. Attack complexity is genuinely low (AC:L) and no authentication is required (PR:N, confirmed by wp_ajax_nopriv_ hook registration), making the attack trivially scriptable. No EPSS score was provided in the source data, limiting probabilistic exploitation forecasting. There is no CISA KEV listing and no POC has been identified, suggesting exploitation remains opportunistic rather than targeted. Real-world risk is bounded by the plugin's relatively niche install base among WordPress AI chatbot adopters. The Trac changeset reference suggests a fix has been committed, which reduces forward-looking exposure for patched installations. The primary risk is data destruction - chatbot configurations, conversation histories, and workflow data - rather than data exfiltration or code execution. |
| Exploit ScenarioDerived | An unauthenticated remote attacker sends a crafted HTTP POST request to a target WordPress site's wp-admin/admin-ajax.php endpoint with the action parameter set to the plugin's removeGroup or clear handler. The authorization gate returns true unconditionally and no nonce is validated, so the server processes the deletion request without any identity check. The attacker can enumerate module names and systematically invoke the clear action to wipe all records from each of the plugin's database tables, destroying all chatbot configurations, conversation history, and workflow automation data stored by the plugin. |

Alert meAnalysisAIv1 – Jul 11, 2026
Unauthenticated mass data deletion in the AI Copilot - Content Generator WordPress plugin (all versions through 1.4.12) exposes sites to complete wipeout of plugin-managed database records by any remote visitor. The vulnerability stems from a permanently open authorization gate: the base controller's getPermissions() returns an empty array causing the auth check to unconditionally pass, while the removeGroup and clear AJAX actions are excluded from getNoncedMethods(), bypassing nonce verification entirely. No active exploitation has been confirmed in CISA KEV and no public exploit code has been identified at time of analysis, though the attack requires no credentials and minimal technical skill given the straightforward AJAX endpoint targeting.
RemediationAI
A fix commit is referenced via the WordPress Plugin SVN changeset (https://plugins.trac.wordpress.org/changeset?reponame=&old=3582369%40ai-copilot-content-generator&new=3582369%40ai-copilot-content-generator), though the exact patched release version number is not independently confirmed from the provided data - upstream fix available (commit/changeset); released patched version not independently confirmed. Administrators should update the AI Copilot - Content Generator plugin to the latest available version immediately via the WordPress dashboard (Plugins > Installed Plugins > Check for Updates). As a compensating control prior to patching, a WAF rule blocking unauthenticated POST requests to wp-admin/admin-ajax.php that include action parameters matching the plugin's removeGroup or clear actions will prevent exploitation, though this may break legitimate unauthenticated plugin AJAX functionality. Alternatively, temporarily deactivating the plugin eliminates all attack surface at the cost of losing chatbot and workflow features. Consult the Wordfence advisory for any updated patch version confirmation.

Technical ContextAI · show details
The affected component is the base controller class of the WordPress plugin (classes/controller.php, lines 112, 133, 142 per Trac references). WordPress exposes AJAX endpoints via wp-admin/admin-ajax.php; actions registered under wp_ajax_nopriv_ are accessible to unauthenticated visitors. The plugin's authorization framework relies on getPermissions() to gate actions and getNoncedMethods() to enforce nonce (CSRF token) checks. Because getPermissions() returns an empty array, the permission resolution logic has no rules to enforce and defaults to granting access unconditionally. Additionally, removeGroup and clear are not listed in getNoncedMethods(), so nonce validation is skipped entirely. CWE-862 (Missing Authorization) is the precise root cause: authorization logic exists in the framework but is rendered inert by misconfiguration of the permission and nonce method registries. The affected CPE is cpe:2.3:a:wupsales:ai_copilot_-_content_generator:*:*:*:*:*:*:*:*, covering the wupsales vendor's plugin up to version 1.4.12.

DescriptionCVE.org
The AI Chatbot & Workflow Automation by AIWU plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.4.12. This is due to missing capability checks and nonce verification on AJAX actions registered under both wp_ajax_ and wp_ajax_nopriv_ hooks, as the base controller's getPermissions() returns an empty array and neither removeGroup nor clear are added to getNoncedMethods(), causing the authorization gate to unconditionally return true for these actions. This makes it possible for unauthenticated attackers to delete specific records by ID or delete all records from any module's database table by unauthenticated attackers.
