CVE-2022-4619

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.
