Name of the Vulnerable Software and Affected Versions Taxonomy Chain Menu plugin for WordPress versions up to, and including, 1.0.8

Description The issue is related to Stored Cross-Site Scripting due to insufficient input sanitization and output escaping on user-supplied attributes in the pn chain menu shortcode. This allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages, which will execute when a user accesses an injected page.

Recommendations For versions up to, and including, 1.0.8, update to a version that addresses the insufficient input sanitization and output escaping issue in the pn chain menu shortcode. As a temporary workaround, consider restricting access to the pn chain menu shortcode for users with contributor-level access and above until a patch is available.
