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 Block Bad Bots and Stop Bad Bots Crawlers and Spiders and Anti Spam Protection plugin for WordPress is vulnerable to unauthorized access of data due to an insufficient capability check on the 'stopbadbots_check_wordpress_logged_in_cookie' function in all versions up to, and including, 11.58. This makes it possible for unauthenticated attackers to bypass blocklists, rate limits, and other plugin functionality.

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 WordPress plugin 'Block Bad Bots and Stop Bad Bots Crawlers and Spiders and Anti Spam Protection' has an insecure direct object reference or broken access control vulnerability. The function 'stopbadbots_check_wordpress_logged_in_cookie' lacks proper WordPress capability checks, allowing unauthenticated attackers to bypass blocklists, rate limits, and other security controls implemented by the plugin.

MitigationUpdate the plugin to the latest version once available, which should include proper capability checks on the affected function. If no update is available, restrict access to the vulnerable function or temporarily disable the plugin.

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 the plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Block Bad Bots and Stop Bad Bots Crawlers and Spiders and Anti Spam Protection' or search for 'stopbadbots' in the plugins directory
    Affected if The plugin appears in the installed plugins list
  2. Identify the installed plugin version
    Click on the plugin in the WordPress plugins list to view its details, or check the main plugin file header for the Version field
    Affected if Any version is installed since no specific safe version range was provided
  3. Confirm the vulnerable function exists
    Inspect the plugin files (typically in wp-content/plugins/stopbadbots/) and locate the function 'stopbadbots_check_wordpress_logged_in_cookie' in the source code
    Affected if The function exists in the plugin files without capability checks
  4. Test for authentication bypass
    Make an unauthenticated HTTP request to a protected page or API endpoint that should be blocked by the plugin's blocklist or rate limiting, then verify if the request is not blocked as expected
    Affected if Unauthenticated requests bypass the plugin's security controls (blocklists, rate limits)
  5. Review function capability checks
    Examine the source code of the affected function to verify if it includes current_user_can() or similar WordPress capability validation before performing security-critical operations
    Affected if No capability check (like current_user_can) is present at the beginning of the function

If the plugin is installed and the vulnerable function lacks capability checks, the environment is affected by this authentication bypass vulnerability.
