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 checksWork through these to decide whether this CVE applies to you.
-
Verify Spectra plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'Spectra' or 'Ultimate Addons for Gutenberg' by Brainstorm Force. Alternatively, check the /wp-content/plugins/ directory for a folder containing 'spectra' or 'uagb'.Affected if The Spectra plugin is installed and active
-
Check installed plugin versionIn WordPress admin, click on the Spectra plugin to view details and note the version number, or inspect the plugin's main PHP file header for 'Version:' tag.Affected if Version is 2.3.0 or lower (any version below 2.3.1)
-
Confirm login/registration forms are exposedVisit the site login page (wp-login.php) and any frontend login/registration forms created with Spectra widgets. Check if these endpoints respond without any rate limiting headers or challenges.Affected if Authentication endpoints are accessible and respond normally without rate limiting or CAPTCHA challenges
-
Check for external rate limiting protectionsInspect HTTP response headers for rate limiting (X-RateLimit-Limit, Retry-After). Test by sending multiple rapid POST requests to the login endpoint using curl or Burp. Check if the server or WAF returns 429 errors or blocks after multiple attempts.Affected if No rate limiting is enforced at the server, WAF, or application level, and multiple rapid auth attempts succeed without restriction
The environment is affected if the Spectra plugin versions below 2.3.1 are installed and no external rate limiting or account lockout mechanism is in place to protect authentication endpoints.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2.3.1
Implement proper rate limiting on authentication endpoints, add account lockout after failed attempts, and enforce progressive delays or CAPTCHA after threshold failures to prevent brute-force attacks.
2.3.1
- Log in to the WordPress admin dashboard
- Navigate to Plugins > Installed Plugins
- Locate the Spectra plugin in the list
- Check if the current version is below 2.3.1
- If update available, click 'Update Now' to upgrade to version 2.3.1 or later
- Alternatively, navigate to Dashboard > Updates and apply all available updates
- After updating, verify the plugin version shows 2.3.1 or higher
