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 Otter Blocks – Gutenberg Blocks, Page Builder for Gutenberg Editor & FSE plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the id parameter in the google-map block in all versions up to, and including, 2.6.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with contributor access and higher 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 · high confidence

The Otter Blocks WordPress plugin is vulnerable to Stored Cross-Site Scripting (XSS) in its google-map block. The 'id' parameter lacks proper input sanitization and output escaping, allowing authenticated users with contributor-level access or higher to inject malicious JavaScript that executes when other users access affected pages.

MitigationUpdate to version 2.6.5 or later which contains the patch; until then, limit contributor-level access and audit existing content for injected scripts.

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 Otter Blocks plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Otter Blocks' by Themeisle, or check the filesystem at wp-content/plugins/otter-blocks/ for the plugin folder
    Affected if The plugin is present in the WordPress installation
  2. Determine installed plugin version
    In WordPress admin Plugins page, click on the Otter Blocks plugin to view its version number, or read the main plugin PHP file header for the Version field
    Affected if Version is less than 2.6.5 (e.g., 2.6.4, 2.6.3, etc.)
  3. Identify google-map blocks in content
    Search WordPress posts/pages for 'otter-google-map' block type. Use WP-CLI: wp post list --all --format=ids | xargs -I{} wp post meta list {} | grep -i 'block' or inspect content via REST API. Alternatively, search database for 'otter-google-map' in wp_posts table
    Affected if Any google-map blocks exist in published content
  4. Check for injected scripts in google-map block IDs
    Examine the 'id' attribute value in any google-map blocks found. Look for suspicious patterns like <script tags, javascript:, or event handlers (onclick, onerror) embedded in the ID field. Inspect page source of affected frontend pages
    Affected if The id parameter contains unescaped HTML or JavaScript code (e.g., <img src=x onerror=alert(1)> used as an ID)
  5. Audit user roles with contributor access
    In WordPress admin, go to Users > All Users and review roles. Contributors can inject malicious code if they can create or edit posts containing google-map blocks. Check if untrusted users have contributor-level or higher access
    Affected if Untrusted or external users have contributor, author, or editor roles with ability to create/edit content containing google-map blocks

You are affected if Otter Blocks version is below 2.6.5 AND google-map blocks with crafted 'id' values exist in your content, especially if untrusted users have contributor-level access.

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 · scoped
Upgrade available Upgrade to 2.6.5 or later
Fixed in 2.6.5
Interim mitigation

Update to version 2.6.5 or later which contains the patch; until then, limit contributor-level access and audit existing content for injected scripts.

Recommended fix High confidence

Otter Blocks version 2.6.5

  1. Backup your WordPress site database and files before making any changes
  2. Navigate to Dashboard > Plugins in your WordPress admin panel
  3. Locate 'Otter Blocks' in the installed plugins list
  4. Click 'Update now' if an update is available, or manually upload version 2.6.5 of Otter Blocks
  5. After updating, verify the plugin version shows 2.6.5 in the Plugins list
  6. Test the Google Maps block functionality to ensure it works correctly with the update
  7. Clear any caching plugins or server-side caches if present
  8. Review pages using the Google Maps block to confirm the XSS payload is no longer executable
Caveat Minor plugin updates typically contain bug fixes and security patches without breaking changes; test in staging if concerned about compatibility with custom themes or other plugins
