Summary

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.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
