Name of the Vulnerable Software and Affected Versions The Sidebar Widgets by CodeLights plugin for WordPress versions up to, and including, 1.4

Description The issue is related to Stored Cross-Site Scripting via the Extra CSS class parameter due to insufficient input sanitization and output escaping. This allows authenticated attackers with administrator-level permissions and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The issue only affects multi-site installations and installations where unfiltered html has been disabled.

Recommendations For versions up to, and including, 1.4, consider disabling the Extra CSS class parameter until a patch is available to prevent exploitation. Restrict access to administrator-level permissions to minimize the risk of arbitrary web script injection.
