Technical summary

The Independent Analytics plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 404 not_found_url tracking parameter in versions up to, and including, 2.15.0. The vulnerability arises from the get_cell_content() function applying urldecode() after esc_url() when rendering the URL column for 404 entries. This sequence allows percent-encoded HTML to pass URL validation and then be reconstructed as raw markup, which wp_kses_post() does not strip because it retains img elements and data-* attributes.

Defensive priority

WordPress Independent Analytics plugin users should prioritize updating to a patched version to prevent potential XSS attacks.

Recommended defensive actions

• Update the Independent Analytics plugin to a version newer than 2.15.0
• Implement additional security measures to monitor and restrict user input
• Regularly review and update plugins to prevent similar vulnerabilities
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
