Cross-site scripting (XSS) vulnerability in Fidra Lighthouse CMS 1.1.0 and earlier allows remote attackers to inject arbitrary web script or HTML via the search parameter in a query_string to the home page. NOTE: The vendor disputes this issue, saying "Lighthouse does not in any way make use of the PHP technology. [It] is an application server ... A technology like this cannot be susceptible to client-side cross-site-scripting-attacks on its own, but only applications created based on such a technology. This does not only apply to Lighthouse, but also to Perl, PHP or web applications based on Java Servlet technology." Since the original researcher is known to test demo pages and is sometimes inaccurate, it is likely that this issue will be REJECTED

Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
