What is CVE-2020-37235?

The Wibar theme version 1.1.8 for WordPress is susceptible to a stored cross-site scripting vulnerability within the Brand component. This flaw enables authenticated users—specifically those with editor, administrator, contributor, or author roles—to inject malicious scripts by manipulating the Logo URL parameter. Through the ftc_brand_url input field, attackers can embed base64-encoded script payloads, leading to the execution of arbitrary JavaScript when users navigate to the affected brand page, compromising user experience and site integrity.
