CVE-2026-4161: Review Map by RevuKangaroo <= 1.7 - Authenticated (Administrator+) Stored Cross-Site Scripting via Plugin Settings

The Review Map by RevuKangaroo plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin settings in all versions up to, and including, 1.7 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Security readout for executives and security teams

Plain-English summary

CVE-2026-4161 is a stored cross-site scripting issue in the WordPress plugin Review Map by RevuKangaroo through version 1.7. It requires an authenticated administrator or higher. Business urgency is limited for most sites, but relevant to WordPress multisite environments or sites where unfiltered_html is disabled.

Executive priority

Treat as a targeted cleanup item, not an emergency, unless affected sites have many administrators or weak admin governance. Prioritize validation on multisite WordPress environments and externally important sites using the plugin.

Technical view

The plugin settings insufficiently sanitize input and escape output, allowing stored script injection that executes when an affected page is viewed. CVSS is 4.4 with high privileges and high attack complexity. Sources state the issue affects multisite installations and installations where unfiltered_html has been disabled.

Likely exposure

Exposure is limited to WordPress sites using Review Map by RevuKangaroo version 1.7 or earlier, specifically multisite deployments or sites with unfiltered_html disabled. Attackers need administrator-level access or higher, reducing external exposure.

Exploitation context

The source bundle does not indicate active exploitation, and KEV is false. Exploitation requires privileged WordPress access and a vulnerable configuration. Impact is mainly script execution in user browsers, with possible confidentiality and integrity effects.

Researcher notes

Evidence identifies CWE-79 stored XSS via plugin settings and references WordPress Trac lines for affected code in trunk and tag 1.7. The public data does not name a fixed version. Avoid assuming remediation beyond vendor guidance, update availability, or plugin removal.

Mitigation direction

  • Inventory WordPress sites for Review Map by RevuKangaroo version 1.7 or earlier.
  • Check vendor and WordPress plugin guidance for an updated fixed version or removal advice.
  • Restrict administrator access to trusted personnel only.
  • Review whether vulnerable multisite or unfiltered_html-disabled configurations are in use.
  • Disable or remove the plugin if business need is low and no fix is available.

Validation and detection

  • Confirm whether the plugin is installed and active on each WordPress site.
  • Record installed plugin version and compare against version 1.7 or earlier.
  • Identify whether the site is WordPress multisite.
  • Check whether unfiltered_html has been disabled.
  • Review plugin settings for unexpected or unauthorized content changes.
