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 PickPlugins Post Grid and Gutenberg Blocks post-grid allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Post Grid and Gutenberg Blocks: from n/a through <= 2.3.23.

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 PickPlugins Post Grid and Gutenberg Blocks WordPress plugin <= 2.3.23 contains an authorization bypass vulnerability where a user-controlled key parameter allows attackers to circumvent access control checks. The vulnerability stems from incorrectly configured security levels in access control logic.

MitigationUpdate the plugin to the latest patched version once available. Conduct a security audit of the plugin's access control implementation to identify and remediate similar vulnerabilities.

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 the plugin installation directory
    Access your WordPress installation via file system or FTP. Navigate to wp-content/plugins/ and locate the folder named 'post-grid' or 'post-grid-gutenberg-blocks'.
    Affected if The plugin folder exists in the WordPress plugins directory.
  2. Read the installed plugin version
    Open the main plugin file (typically post-grid/post-grid.php) and locate the 'Version' field in the plugin header comment at the top of the file.
    Affected if The reported version number is 2.3.23 or lower.
  3. Verify the plugin is active
    In the WordPress admin dashboard, go to Plugins > Installed Plugins. Check if 'Post Grid' or 'Post Grid and Gutenberg Blocks' is listed as 'Active'.
    Affected if The plugin shows as Active.
  4. Inspect access control files for vulnerable key parameter pattern
    Examine the plugin files containing access control logic, typically in files named 'access.php', 'security.php', or files handling AJAX endpoints. Look for code that uses a user-supplied key parameter (such as $_GET['key'], $_POST['key'], or similar) in access control decision-making without proper validation.
    Affected if Code exists that uses a user-controlled 'key' parameter in access control checks without proper validation or authorization verification.

You are affected if the plugin version is 2.3.23 or lower, the plugin is active, and the vulnerable user-controlled key parameter pattern exists in the access control logic.
