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 Customer Area plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'type' attribute of the `customer-area-protected-content` shortcode in all versions up to, and including, 8.3.5. This is due to insufficient input sanitization and output escaping on the shortcode attribute. 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 Customer Area plugin for WordPress contains a stored XSS vulnerability in the `customer-area-protected-content` shortcode. The 'type' attribute lacks proper input sanitization and output escaping, allowing authenticated users with Contributor-level permissions or higher to inject arbitrary JavaScript that executes when other users view affected pages.

MitigationUpdate the plugin to a version beyond 8.3.5 that addresses this vulnerability, or implement proper sanitization (such as using WordPress sanitization functions like `sanitize_text_field()`) and output escaping (such as `esc_attr()`) on the 'type' attribute in the shortcode handler.

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 WP Customer Area plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for 'WP Customer Area' or 'Customer Area' in the list. Note the installed version displayed.
    Affected if Plugin is installed and version is 8.3.5 or lower (versions beyond 8.3.5 are not affected)
  2. Verify the shortcode is in use
    Search WordPress database or content: look for occurrences of the shortcode `[customer-area-protected-content]` in posts, pages, or custom post types. Can use WP admin search or query the wp_posts table for post_content containing 'customer-area-protected-content'.
    Affected if The shortcode is present in any published content and the plugin version is vulnerable
  3. Check user role permissions
    Go to Users > All Users in WordPress admin. Review the role column to identify users with Contributor, Author, Editor, or Administrator roles (these have Contributor-level or higher permissions).
    Affected if Any user account with Contributor-level or higher access exists on the site
  4. Inspect shortcode handler for sanitization (optional manual check)
    If you have file access, locate the plugin file containing the `customer-area-protected-content` shortcode handler (typically in includes/class-xx.php or similar). Look for `sanitize_text_field()` or `esc_attr()` on the 'type' attribute. If missing, the vulnerability exists.
    Affected if The shortcode handler lacks proper input sanitization and output escaping on the 'type' attribute

You are affected if the WP Customer Area plugin is installed at version 8.3.5 or lower AND the customer-area-protected-content shortcode is in use AND at least one user with Contributor-level or higher permissions exists on the site.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update the plugin to a version beyond 8.3.5 that addresses this vulnerability, or implement proper sanitization (such as using WordPress sanitization functions like `sanitize_text_field()`) and output escaping (such as `esc_attr()`) on the 'type' attribute in the shortcode handler.
