Name of the Vulnerable Software and Affected Versions Xavin's List Subpages plugin for WordPress versions up to and including 1.3

Description The issue arises from insufficient input sanitization and output escaping on user-supplied attributes in the 'xls' shortcode. This allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts in pages. These scripts will execute when a user accesses an injected page.

Recommendations For versions up to and including 1.3, consider disabling the 'xls' shortcode until a patch is available to prevent exploitation. Restrict access to the shortcode's attributes to minimize the risk of arbitrary script injection.
