Description
Fossil 2.18 on Windows allows attackers to cause a denial of service (daemon crash) via an XSS payload in a ticket. This occurs because the ticket data is stored in a temporary file, and the product does not properly handle the absence of this file after Windows Defender has flagged it as malware.
