Name of the Vulnerable Software and Affected Versions The List Children plugin for WordPress versions up to, and including, 2.1

Description The issue is related to Stored Cross-Site Scripting via the plugin's 'list children' shortcode due to insufficient input sanitization and output escaping on user-supplied attributes. This allows 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.

Recommendations For versions up to, and including, 2.1, update to a version that addresses the insufficient input sanitization and output escaping issue in the 'list children' shortcode. As a temporary workaround, consider restricting access to the 'list children' shortcode for users with contributor-level access and above until a patch is available.
