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 Betheme theme for WordPress is vulnerable to Stored Cross-Site Scripting via several of the plugin's shortcodes in all versions up to, and including, 27.5.6 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 Betheme WordPress theme contains a stored XSS vulnerability in multiple shortcode implementations due to insufficient input sanitization and output escaping on user-supplied attributes. Authenticated attackers with contributor-level permissions or higher can inject malicious JavaScript into pages via shortcode attributes, which executes when other users view the compromised content.

MitigationUpdate Betheme theme to version 27.5.7 or later to apply the patch. Review existing shortcode usage on the site for any malicious injections that may have been added prior to patching.

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 installed Betheme theme version
    Access the theme's style.css file in wp-content/themes/betheme/ and locate the 'Version' header in the file comments, or use WordPress admin under Appearance > Themes to view the active theme version
    Affected if The installed version is 27.5.6 or any lower version number
  2. Verify shortcode functionality is active
    Search your WordPress database (wp_posts table) for common Betheme shortcode patterns such as '[mfn_', '[section_', '[builder_', or examine page/post content where Betheme's layout builder shortcodes are used
    Affected if Shortcode content exists in posts, pages, or custom post types on the site
  3. Inspect shortcode attributes for unsanitized input
    Review stored content containing Betheme shortcodes and examine the attribute values (parameters within quotes after the shortcode name) for any unexpected HTML, JavaScript tags, or event handlers such as onmouseover, onerror, or javascript:
    Affected if Any shortcode attributes contain raw HTML, script tags, or JavaScript event handlers that are not properly escaped or encoded
  4. Check for suspicious content in contributor-level posts
    If you have multiple authors, query the wp_posts table for entries authored by users with contributor or author roles and review their published content for any unusual shortcode injections
    Affected if Content authored by lower-privileged users contains shortcodes with potentially malicious attribute values

You are affected if the Betheme theme version is 27.5.6 or lower AND any Betheme shortcodes in your content contain unsanitized HTML or JavaScript in their attributes.

dbcve · scoped
Upgrade available Upgrade to a release after 27.5.6
Interim mitigation

Update Betheme theme to version 27.5.7 or later to apply the patch. Review existing shortcode usage on the site for any malicious injections that may have been added prior to patching.

Recommended fix Moderate confidence

Betheme version 27.5.7 or later (check theme vendor for latest stable release)

  1. Check the theme update notifications in WordPress admin dashboard under Appearance > Themes
  2. If no update is shown, manually check for updates via Dashboard > Updates or contact the theme vendor
  3. Update Betheme to the latest available version (version 27.5.7 or later)
  4. After updating, verify that all shortcodes function correctly on the site
  5. Clear any caching plugins if installed
  6. Review pages using Betheme shortcodes to ensure no malicious scripts were injected prior to the update
Caveat Minor theme updates typically have low risk, but always backup the site before updating; some custom shortcode implementations may need testing
