Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Missing Authorization vulnerability in quadlayers AI Copilot ai-copilot allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects AI Copilot: from n/a through <= 1.5.2.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The AI Copilot plugin by quadlayers has a missing authorization vulnerability that allows attackers to exploit incorrectly configured access control security levels. This broken access control issue enables unauthorized users to access functionality that should require proper authentication and authorization, likely due to missing capability checks or nonce validations on sensitive functions.

MitigationUpdate the AI Copilot plugin to the latest version when available, and conduct a security audit of all admin and user-facing functions to ensure proper capability checks and authorization gates are in place.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify if AI Copilot plugin is installed
    Navigate to WordPress admin dashboard > Plugins, or inspect the wp-content/plugins directory for a folder containing 'ai-copilot' or 'quadlayers' related to AI Copilot functionality
    Affected if The AI Copilot plugin by quadlayers appears in the installed plugins list
  2. Determine installed plugin version
    In WordPress admin > Plugins > AI Copilot, check the version number displayed below the plugin name; alternatively, inspect the plugin's main PHP file header for 'Version:' tag
    Affected if The version number cannot be verified or is older than the latest patched version available from quadlayers
  3. Identify admin functions lacking authorization
    Review plugin source code files (especially AJAX handlers, API endpoints, and admin menu callbacks) for missing capability checks - look for functions that execute sensitive operations without current_user_can() or similar authorization validation
    Affected if Any admin action handlers, AJAX endpoints, or callback functions are found without proper capability checks before executing sensitive operations
  4. Check for unprotected AJAX endpoints
    Inspect plugin AJAX action registrations (add_action('wp_ajax_...')) and verify each includes nonce validation and capability checks; examine public-facing AJAX handlers (wp_ajax_nopriv_...) that should require authentication
    Affected if AJAX endpoints exist that handle sensitive operations without nonce verification or capability checks, or allow nopriv (unauthenticated) access to protected functions
  5. Audit REST API routes if present
    If the plugin registers REST API routes, review route definitions for missing permission_callback functions that verify user capabilities before granting access
    Affected if REST API endpoints are registered without permission_callback functions or with permissive callbacks that allow unauthorized access to sensitive data or actions

A user is affected if the AI Copilot plugin is installed and contains admin functions, AJAX endpoints, or REST routes that execute without proper capability checks or nonce validation, allowing unauthorized access to sensitive functionality.
