CVE-2023-52085: Wintercms Winter

Medium severity, CVSS 5.4. EPSS: 30.2% chance of exploitation in the next 30 days.

Winter is a free, open-source content management system. Users with access to backend forms that include a ColorPicker FormWidget can provide a value that would then be included without further processing in the compilation of custom stylesheets via LESS. This had the potential to lead to a Local File Inclusion vulnerability. This issue has been patched in v1.2.4.
