CVE-2025-32370: Kentico Xperience

Critical severity, CVSS 9.8. EPSS: 1.6% chance of exploitation in the next 30 days.

Kentico Xperience before 13.0.178 has a specific set of allowed ContentUploader file extensions for unauthenticated uploads; however, because .zip is processed through TryZipProviderSafe, there is additional functionality to create files with other extensions. NOTE: this is a separate issue not necessarily related to SVG or XSS.
