CVE-2022-34009: Fossil-Scm Fossil

Medium severity, CVSS 5.5. EPSS: 0.4% chance of exploitation in the next 30 days.

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.
