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 WP Cerber Security plugin for WordPress is vulnerable to stored cross-site scripting via the log parameter when logging in to the site in versions up to, and including, 9.1. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

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 WP Cerber Security plugin for WordPress versions up to 9.1 contains a stored XSS vulnerability. Unauthenticated attackers can inject malicious JavaScript via the login 'log' parameter, which gets stored in the plugin's log system. When administrators later view these logs in the WordPress dashboard, the injected scripts execute in their browsers.

MitigationUpdate WP Cerber Security plugin to version 9.2 or later to patch the XSS vulnerability. Until then, consider disabling the plugin or restricting admin access to the logging functions.

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 WP Cerber Security plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Cerber Wp Cerber Security, Anti Spam & Malware Scan' or check the /wp-content/plugins/cerber-security/ directory exists on the server
    Affected if The plugin is installed and active
  2. Check installed plugin version
    In WordPress admin, go to Plugins > Installed Plugins and click on the WP Cerber Security plugin to view its version, or inspect the main plugin file header for the Version field
    Affected if The installed version is less than 9.2 (for example, 9.1, 9.0, 8.x, etc.)
  3. Confirm logging feature is enabled
    Go to WP Cerber Security > Activity Log in the WordPress dashboard and verify that logging is active; alternatively, check if the cerber-log-* files exist in /wp-content/uploads/cerber/
    Affected if Logging is enabled and storing login attempts
  4. Inspect login logs for suspicious entries
    Navigate to WP Cerber Security > Activity Log in the admin panel and examine recent login entries, particularly looking for the 'log' parameter values that contain HTML, script tags, or unusual characters
    Affected if Log entries contain unescaped HTML, script tags, or encoded characters that could indicate injection attempts

You are affected if WP Cerber Security plugin versions below 9.2 are installed and the logging feature is enabled, as unauthenticated XSS injection via the login log parameter can be stored and triggered when you view the logs.
