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

Missing Authorization (Broken Access Control) vulnerability in the PickPlugins Post Grid and Gutenberg Blocks WordPress plugin allows authenticated users to access or modify resources they should not have permission to access, due to incorrectly configured access control security levels.

MitigationImplement proper authorization checks (capability verification using current_user_can() and nonce validation) on all sensitive AJAX handlers and front-end actions within the plugin; update to the patched version if available.

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. Verify PickPlugins Post Grid plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Post Grid and Gutenberg Blocks' by PickPlugins, or run command: ls wp-content/plugins/ | grep -i 'post-grid'
    Affected if Plugin directory exists in wp-content/plugins/
  2. Check installed plugin version
    Click on the plugin in the Plugins list to view version details, or inspect the plugin main PHP file header for 'Version:' field, or run: grep -r 'Version:' wp-content/plugins/post-grid/ | head -5
    Affected if Version is unknown or cannot be compared to a patched release
  3. Identify AJAX handlers in the plugin
    Search the plugin directory for AJAX action registrations: grep -r 'add_action.*wp_ajax' wp-content/plugins/post-grid/ or look for files in /src/ or /classes/ folders containing 'wp_ajax_'
    Affected if AJAX handlers are present in the plugin code
  4. Verify AJAX handlers have capability checks
    Open each PHP file containing AJAX handlers and search for 'current_user_can' or 'check_ajax_referer' before any sensitive database operations or data modifications. Example: grep -B5 -A5 'wp_ajax_' wp-content/plugins/post-grid/[ajax_handler_file].php
    Affected if AJAX handlers execute without calling current_user_can() or equivalent authorization functions
  5. Check for nonce validation on front-end actions
    Search the plugin for form submissions or GET/POST requests handling sensitive operations: grep -r 'wp_ajax_nopriv' wp-content/plugins/post-grid/ and verify if these handlers include proper user capability verification
    Affected if Public or low-privilege user actions are processed without verifying user permissions

If the plugin is active and any AJAX handlers or sensitive functions lack proper current_user_can() checks or nonce validation, the environment is vulnerable to CVE-2025-66058

Mitigation

Implement proper authorization checks (capability verification using current_user_can() and nonce validation) on all sensitive AJAX handlers and front-end actions within the plugin; update to the patched version if available.

Recommended fix Moderate confidence

Version 2.3.18 or later (any version newer than 2.3.17)

  1. 1. Log in to your WordPress admin dashboard
  2. 2. Navigate to Plugins > Installed Plugins
  3. 3. Locate 'Post Grid and Gutenberg Blocks' by PickPlugins
  4. 4. If an update is available, click 'Update Now' to install the latest version
  5. 5. Alternatively, download the latest version from the WordPress plugin repository or PickPlugins website
  6. 6. After updating, verify the plugin is functioning correctly and test the post grid functionality
Caveat Review the plugin changelog for any breaking changes between your current version and the new version before updating in production
