Name of the Vulnerable Software and Affected Versions:

List category posts plugin for WordPress versions up to, and including, 0.89.6

Description:

The issue is related to Stored Cross-Site Scripting via the plugin's 'catlist' shortcode due to insufficient input sanitization and output escaping on user-supplied attributes like `title tag`. This allows authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Recommendations:

For versions up to, and including, 0.89.6, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider restricting access to the 'catlist' shortcode for users with contributor-level and above permissions to minimize the risk of exploitation. Avoid using the `title tag` attribute in the 'catlist' shortcode until the issue is resolved.
