Short explanation
TYPO3 CMS versions 14.0.0 through 14.3.8 store uploaded files in the default storage folder 1:/user_upload/ instead of the configured destination when using FileUpload or ImageUpload elements with a custom saveToFileMount. This causes uploaded files to end up in a publicly accessible storage and be served directly without access checks.
This security misconfiguration can lead to sensitive uploaded files being exposed to public access and served directly to users without proper authorization checks, creating confidentiality risks.
What should be done?
- Monitor vendor advisories for updates
- Review forms configured with a custom saveToFileMount
Chain of evidence and sources

Show the technical text from the sources
Forms using FileUpload or ImageUpload elements with a custom saveToFileMount configured stored uploaded files in the default storage folder 1:/user_upload/ instead of the configured destination. This could cause uploaded files to end up in a publicly accessible storage even though a restricted, non-public storage had been configured. Files stored this way are served directly, without the access checks applied to non-public storages. Forms that use the default value for saveToFileMount are not affected. This issue affects TYPO3 CMS versions 14.0.0-14.3.8.
