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.
-
Check Spectra plugin versionIn WordPress admin, go to Plugins > Installed Plugins and locate 'Spectra' or 'Ultimate Addons for Gutenberg' by Brainstorm Force. Note the installed version number.Affected if The installed version is lower than 2.3.1 (e.g., 2.3.0, 2.2.x, etc.)
-
Identify user input fields in Spectra elementsReview which Spectra blocks or widgets on your site accept user-provided text input. Common areas include custom text fields, heading settings, button text, and content blocks.Affected if User input fields exist in any Spectra blocks on your site and the plugin version is below 2.3.1
-
Inspect stored content for unsanitized script tagsExamine the database or page content where Spectra user inputs are stored. Look for HTML script tags, iframe tags, or JavaScript event handlers (onerror, onload, onclick) that may have been injected into text fields.Affected if Any stored content contains unescaped script-related HTML tags such as <script>, <iframe>, or event handler attributes like onerror/onload in Spectra-generated pages
Your site is affected if the Spectra plugin version is below 2.3.1 and any Spectra blocks accept user input that could be rendered on the frontend without sanitization.
Generated from the published advisory. Verify against your own configuration.
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.
