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.

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 Internal Links Manager plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'Internal Links Manager' in the list
    Affected if The plugin appears in the installed plugins list regardless of activation status
  2. Check installed plugin version
    Click on the plugin name in the WordPress plugins list or view the plugin's main PHP file header (usually in wp-content/plugins/internal-links-manager/) to read the 'Version' comment
    Affected if The reported version is 3.0.3 or any version lower (e.g., 3.0.2, 3.0.1, 3.0.0)
  3. Confirm plugin is active
    In WordPress admin > Plugins, verify the plugin has an 'Active' status under the Internal Links Manager entry
    Affected if The plugin is activated - the XSS is reachable without authentication when the plugin is active
  4. Inspect internal link handling functionality
    If the plugin provides a shortcode or frontend interface for internal links (check plugin settings or documentation), attempt to identify where user-supplied input is processed for link parameters
    Affected if The plugin accepts URL parameters or user input for internal link generation without visible sanitization - however, version comparison in step 2 is the primary indicator of exposure

You are affected if Internal Links Manager plugin is installed and active with version 3.0.3 or lower.

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.
