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 vulnerability in WP-RecentComments WordPress plugin versions through 2.2.7 allows unauthorized users to exploit incorrectly configured access control security levels. The plugin fails to properly enforce authorization checks, enabling attackers to access or manipulate data that should require proper authentication or elevated privileges.

MitigationImplement proper capability checks and authorization validation in all plugin functions that handle user data or comment display functionality. Ensure WordPress nonces are validated for any state-changing operations.

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. Confirm WP-RecentComments plugin is installed
    Access the WordPress admin dashboard, go to Plugins > Installed Plugins, and search for 'WP-RecentComments'. Alternatively, check if the /wp-content/plugins/wp-recent-comments/ or similar plugin directory exists on the server.
    Affected if Plugin directory exists in wp-content/plugins/
  2. Identify the installed plugin version
    In the WordPress admin Plugins page, locate WP-RecentComments and view the version number displayed under the plugin name. If accessing the server directly, open the main plugin PHP file (e.g., wp-recent-comments.php) and look for the 'Version' header in the plugin comments.
    Affected if Version listed is 2.2.7 or any earlier version (the vulnerability affects versions through 2.2.7)
  3. Test for unauthorized comment access
    With a low-privileged user account (subscriber or logged-out visitor), attempt to access WordPress AJAX endpoints or frontend shortcodes provided by WP-RecentComments that display comments. Check if comment content from protected or private posts is exposed without proper capability verification.
    Affected if Comment data from posts requiring higher privileges is visible to unauthenticated or low-privilege users
  4. Verify admin action accessibility
    Attempt to access plugin-specific admin pages or AJAX actions without administrator privileges. Check if functions like comment moderation, settings changes, or data export are reachable without proper capability checks using a non-admin account or while logged out.
    Affected if Administrative functions or comment management features are accessible to users lacking manage_options or edit_comments capabilities

Your environment is affected if the WP-RecentComments plugin is installed at version 2.2.7 or earlier AND comment data or admin functions are accessible without proper WordPress capability validation.
