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
The Search Exclude plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the get_rest_permission function in all versions up to, and including, 2.4.9. This makes it possible for unauthenticated attackers to modify plugin settings, excluding content from search results.

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 · high confidence

The Search Exclude WordPress plugin lacks a capability check on its get_rest_permission function, allowing unauthenticated attackers to access the plugin's REST API endpoint and modify settings to exclude arbitrary content from WordPress search results.

MitigationUpdate the Search Exclude plugin to version 2.5.0 or later which implements proper capability checks on the REST permission callback. Alternatively, disable the plugin until a patch is 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. Confirm Search Exclude plugin is installed
    Navigate to WordPress admin > Plugins and look for 'Search Exclude' in the installed plugins list, or check the filesystem at wp-content/plugins/search-exclude/
    Affected if The Search Exclude plugin is present and active on the WordPress site
  2. Check the installed plugin version
    In WordPress admin > Plugins > Search Exclude, view the plugin details to see the version number, or read the main plugin file header at wp-content/plugins/search-exclude/search-exclude.php
    Affected if The installed version is lower than 2.5.0 (versions prior to 2.5.0 lack the capability check)
  3. Inspect REST API permission callback
    Locate the get_rest_permission function in the plugin file (typically in search-exclude.php or includes/class-search-exclude.php) and verify if it performs a capability check such as current_user_can('manage_options') before allowing access
    Affected if The get_rest_permission function exists but contains no capability check or always returns true, allowing unauthenticated access
  4. Test REST endpoint accessibility
    Send a GET request to the plugin's REST endpoint (typically /wp-json/search-exclude/v1/settings or /wp-json/search-exclude/v1/excluded-posts) without providing authentication credentials
    Affected if The REST API responds with data or allows modifications without requiring authentication (status 200 rather than 401/403)

A WordPress site running Search Exclude plugin versions before 2.5.0 with an exposed and unauthenticated-accessible REST API endpoint is affected by this vulnerability.
