CVE-2026-1806: Tour & Activity Operator Plugin for TourCMS <= 1.7.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes

The Tour & Activity Operator Plugin for TourCMS plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'target' parameter of the tourcms_doc_link shortcode in all versions up to, and including, 1.7.0 due to insufficient input sanitization and output escaping. 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.

Security readout for executives and security teams

Plain-English summary

CVE-2026-1806 affects the Tour & Activity Operator Plugin for TourCMS WordPress plugin through version 1.7.0. A logged-in user with Contributor or higher privileges can save malicious script in shortcode content. That script can run when someone views the affected page, potentially impacting visitors or administrators.

Executive priority

Treat as a near-term web security cleanup, not an emergency based on current evidence. Prioritize sites with many content contributors, partner accounts, or administrative users who frequently view contributed pages.

Technical view

This is authenticated stored cross-site scripting in the tourcms_doc_link shortcode’s target parameter. Sources attribute it to insufficient input sanitization and output escaping. CVSS 3.1 is 6.4 with low attack complexity, low privileges required, changed scope, and limited confidentiality and integrity impact.

Likely exposure

Exposure is limited to WordPress sites using the Tour & Activity Operator Plugin for TourCMS up to and including 1.7.0, especially where Contributor-level accounts are available to untrusted users or external content creators.

Exploitation context

The source bundle does not indicate known active exploitation, and KEV status is false. Exploitation requires authenticated Contributor-level or higher access, but successful stored XSS can affect later page viewers without further attacker interaction.

Researcher notes

The affected metadata in the bundle is sparse, but the description and references identify versions up to and including 1.7.0. The vulnerable area is the shortcode handling around tourcms_doc_link target processing. No patch version is named in the provided sources.

Mitigation direction

  • Inventory WordPress sites for the TourCMS tour operator plugin and installed version.
  • Review vendor, WordPress plugin, and Wordfence guidance for an updated fixed release or official mitigation.
  • Restrict Contributor and higher roles to trusted users until remediation is confirmed.
  • Audit pages and posts using the tourcms_doc_link shortcode for suspicious attributes or unexpected scripts.

Validation and detection

  • Confirm whether the plugin is installed and at version 1.7.0 or earlier.
  • Identify users with Contributor, Author, Editor, or Administrator roles on affected sites.
  • Search site content for tourcms_doc_link shortcode usage and review target attributes.
  • Check security logs for recent edits by low-privileged authenticated users.
