Overview

CVE-2026-1866 is a high-severity vulnerability. It was published on February 10, 2026 and has a CVSS 3.1 base score of 7.2 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.2, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

The Name Directory plugin for WordPress is vulnerable to Stored Cross-Site Scripting via double HTML-entity encoding in all versions up to, and including, 1.32.0. This is due to the plugin's sanitization function calling `html_entity_decode()` before `wp_kses()`, and then calling `html_entity_decode()` again on output. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page via the 'name_directory_name' and 'name_directory_description' parameters in the public submission form granted they can trick the site administrator into approving their submission or auto-publish is enabled.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
