Summary

### Impact File validation can be configured to reject certain files by file type. When this happens, validation fails, and the content can't be published. However, the file can be saved when saving the content draft. This means unwanted files can be present in storage, even if they are not easily accessible due to the content not being published. The fix ensures these unwanted file types are never stored. An attacker would need to have existing access to create content with a file field type to exploit this.

### Patches See "Patched versions". Commit: https://github.com/ezsystems/ezplatform-kernel/commit/7e472317f7c75f45f72f74c38406952d8bea0de1

Fencer Intel 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.
