Original NVD Description

MDwiki contains a cross-site scripting vulnerability that allows remote attackers to execute arbitrary JavaScript by injecting malicious code through the location hash parameter. Attackers can craft URLs with JavaScript payloads in the hash fragment that are parsed and rendered without sanitization, causing the injected scripts to execute in the victim's browser context.
