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
A stored cross-site scripting (XSS) vulnerability in October CMS Bloghub Plugin v1.3.8 and lower allows attackers to execute arbitrary web scripts or HTML via a crafted payload into the Comments section.

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

A stored cross-site scripting (XSS) vulnerability exists in the October CMS Bloghub Plugin v1.3.8 and lower. The plugin fails to properly sanitize user input in the Comments section, allowing attackers to inject malicious JavaScript or HTML that executes when other users view the compromised content.

MitigationImplement robust input validation and output encoding/escaping on all user-supplied data in the Comments section. Use aallowlist-based validation and ensure contextual output encoding is applied when rendering comments.

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. Identify if October CMS is running
    Access the website's admin panel or check the application for October CMS signatures (look for octobercms references in source code, cookies, or meta tags)
    Affected if The site runs on October CMS platform
  2. Check if Bloghub plugin is installed
    Navigate to the October CMS backend and inspect the installed plugins list, or check the plugins directory for the Bloghub plugin folder
    Affected if Bloghub plugin is present in the installation
  3. Verify Bloghub plugin version
    In the October CMS backend, view the plugin details for Bloghub to see the installed version number, or check the plugin's version.php or manifest file
    Affected if The installed version is 1.3.8 or lower
  4. Confirm Comments feature is accessible
    Navigate to any blog post that has the Comments section enabled and visible to users (either frontend visitors or backend users)
    Affected if The Comments feature is enabled and accessible to users who can submit content
  5. Inspect comment input handling
    Submit a test comment containing harmless HTML markup (such as <b>test</b> or <script>alert(1)</script>) and then view the comment to see if the markup renders as raw text or executes as HTML/JavaScript
    Affected if The submitted HTML/JavaScript is rendered as active code rather than being escaped or removed

A user is affected if they have October CMS with Bloghub plugin version 1.3.8 or lower installed, and the Comments feature is enabled and accessible to users who can submit content.
