The issue is related to Reflected Cross-Site Scripting via the `tab` parameter due to insufficient input sanitization and output escaping. This allows unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

A cross-site scripting (XSS) issue allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the `durationFormat` parameter. This enables the execution of malicious code on the affected system.

The issue is related to Stored Cross-Site Scripting via admin settings 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.
