CVE-2023-0173: WPFunnels < 2.6.9 - Contributor+ Stored XSS

The Drag & Drop Sales Funnel Builder for WordPress plugin before 2.6.9 does not validate and escape some of its shortcode attributes before outputting them back in a page/post where the shortcode is embed, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks.

Security readout for executives and security teams

Plain-English summary

CVE-2023-0173 is a stored cross-site scripting issue in WPFunnels before 2.6.9. A contributor-level WordPress user could place malicious script through shortcode attributes that the plugin failed to validate and escape. The script could run when another user views the affected page or post.

Executive priority

Treat as a moderate web-content integrity risk. Prioritize patching public WordPress sites with multiple content authors, agencies, contractors, or customer-managed editors. It is less urgent than unauthenticated remote code execution, but stored XSS can affect administrators and site visitors.

Technical view

The plugin did not validate and escape some shortcode attributes before rendering them in embedded page or post output. This is CWE-79 stored XSS with CVSS 3.1 score 5.4: network-reachable, low complexity, low privileges required, user interaction required, changed scope, and low confidentiality and integrity impact.

Likely exposure

Exposure is likely limited to WordPress sites using Drag & Drop Sales Funnel Builder for WordPress, also referenced as WPFunnels, before version 2.6.9, where contributor or higher accounts can create or edit shortcode-bearing content.

Exploitation context

The bundle does not show CISA KEV listing or active exploitation. WPScan is tagged as an exploit and technical-description reference, indicating public vulnerability detail exists, but the provided evidence does not prove real-world exploitation.

Researcher notes

Focus validation on shortcode rendering paths and role-based content workflows. The source data identifies shortcode attribute output escaping as the weakness, contributor-plus privileges as the entry point, and version 2.6.9 as the fixed threshold. Do not assume broader products or unauthenticated exposure from this bundle.

Mitigation direction

  • Update WPFunnels to version 2.6.9 or later.
  • Review vendor and WPScan guidance for any additional remediation.
  • Limit contributor-level content creation to trusted users.
  • Review existing pages and posts containing WPFunnels shortcodes.
  • Remove suspicious shortcode attributes after validation.

Validation and detection

  • Inventory WordPress sites for the affected plugin and version.
  • Confirm WPFunnels is upgraded to 2.6.9 or later.
  • List users with contributor or higher roles.
  • Review WPFunnels shortcode usage in pages and posts.
  • Check recent content changes by lower-privileged authors.
