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
Unauthenticated Cross Site Scripting (XSS) in Blog2Social <= 8.9.2 versions.

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

An unauthenticated Cross Site Scripting (XSS) vulnerability exists in the Blog2Social WordPress plugin affecting versions 8.9.2 and below. The vulnerability allows attackers to inject malicious JavaScript scripts through unsanitized user inputs without requiring authentication.

MitigationUpgrade Blog2Social to the latest version which contains proper input sanitization and output encoding. Until patched, disable the plugin or implement additional WAF rules to block XSS attack vectors.

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. Confirm Blog2Social plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Blog2Social' in the list, or inspect the /wp-content/plugins/ directory for a blog2social folder.
    Affected if The Blog2Social plugin is present in the WordPress installation.
  2. Check installed version number
    In WordPress admin, go to Plugins > Installed Plugins, find Blog2Social, and read the version number displayed below the plugin name. Alternatively, check the main plugin file (e.g., blog2social.php) in /wp-content/plugins/blog2social/ for the 'Version' header in the file comments.
    Affected if The version number is 8.9.2 or lower.
  3. Verify plugin is active
    In WordPress admin, go to Plugins > Installed Plugins and confirm the Blog2Social plugin shows as 'Active' (not just installed but deactivated).
    Affected if The plugin is both installed AND active.
  4. Check for unsanitized input points
    Review the plugin settings and any public-facing forms (such as social sharing configuration, import/export features, or user profile fields that Blog2Social may handle) for user-supplied input fields that accept and display data without visible sanitization indicators.
    Affected if The plugin accepts user input through web forms and displays it back without apparent encoding.

If Blog2Social version 8.9.2 or lower is installed and active, the environment is affected by this unauthenticated XSS vulnerability.
