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
Authorization Bypass Through User-Controlled Key vulnerability in Mikado-Themes Verdure verdure allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Verdure: from n/a through <= 1.6.

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 Verdure theme by Mikado-Themes contains an Insecure Direct Object Reference (IDOR) vulnerability where user-controlled parameters (likely object IDs in requests) are not properly validated against authorization checks, allowing authenticated users to access or modify resources they shouldn't have access to.

MitigationImplement proper authorization validation on all sensitive operations, ensuring object references in requests are verified against the current user's permissions before processing.

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. Locate Verdure theme installation
    Check your themes directory (typically wp-content/themes/verdure or wp-content/themes/mikado-verdure) for the theme folder and locate style.css to read the version from the theme header comment
    Affected if Theme is present and version cannot be determined or matches the vulnerable release
  2. Identify endpoints accepting object IDs
    Search theme PHP files for patterns that accept ID parameters such as $_GET['id'], $_POST['id'], $_REQUEST['id'], or REST API route parameters that reference posts, users, or other objects by numeric ID
    Affected if Theme contains code that processes requests with object ID parameters without authorization validation
  3. Verify authorization logic exists around ID references
    Examine the identified endpoints in theme files for proper permission checks - look for functions that validate the current user owns or has access to the requested object ID before processing (e.g., checking post_author against current_user->ID)
    Affected if Object IDs in requests are processed without verifying the current user has permission to access that specific resource
  4. Check database query patterns for missing ownership validation
    Search theme PHP files for database retrieval functions like get_post($id), get_userdata($id), or WP_Query with ID parameters, then verify if ownership/permission checks occur before outputting or modifying data
    Affected if Data is retrieved or modified using object IDs without confirming the current user's authorization to access that specific object

Environment is affected if Verdure theme is installed and contains endpoints or queries that accept object ID parameters without proper authorization validation against the current user's permissions.
