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 WP-Clippy plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `clippy` shortcode in all versions up to, and including, 1.0.0. This is due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, 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 WP-Clippy WordPress plugin has a stored XSS vulnerability in its clippy shortcode (versions up to 1.0.0). Authenticated users with contributor-level access can inject arbitrary JavaScript via unsanitized shortcode attributes, which executes when other users view the compromised page.

MitigationUpdate the plugin to version 1.0.1 or later which includes proper input sanitization and output escaping. Until patched, restrict contributor-level user creation and review existing shortcode usage.

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 WP-Clippy plugin is installed
    Check your WordPress plugins directory or go to Plugins > Installed Plugins and look for WP-Cloppry or WP-Clippy in the list
    Affected if The plugin appears in the installed plugins list
  2. Determine installed version of WP-Clippy
    On the Plugins page, click on the plugin to view details, or check the plugin header comment in wp-content/plugins/wp-clippy/wp-clippy.php for the Version: line
    Affected if The version is 1.0.0 or any version below 1.0.1
  3. Identify contributor-level user accounts
    Navigate to Users > All Users in the WordPress admin and look for any users with the Contributor role
    Affected if At least one user with Contributor role exists and has the ability to create or edit posts containing shortcodes
  4. Search for clippy shortcode usage in content
    Use WordPress search or query the wp_posts table for content containing the string [clippy] or [clippy_
    Affected if Any post, page, or custom post type contains a clippy shortcode that could have unsanitized attributes

You are affected if the WP-Clippy plugin is installed at version 1.0.0 or below AND at least one Contributor-level user exists AND clippy shortcodes are in use on your site.
