Stored script execution via unescaped CSS class setting

Published Jul 17, 2022 · Updated Aug 3, 2024

Stored cross-site scripting in Sumon Hasan Very Simple Breadcrumb 1.0 and earlier allows remote authenticated users to execute scripts. The Breadcrumb css class name setting accepts attacker-controlled markup and later emits it into a page without sanitization or output escaping. Administrator access is required, but the payload works when the unfiltered_html capability is disabled and runs in browsers that render the affected breadcrumb.
