- Files within the storage/ path could be accessed via path traversal
references in content, accessed upon HTML export.
- This addresses this via two layers:
- Scoped local flysystem filesystems down to the specific image &
file folders since flysystem has built-in checking against the
escaping of the root folder.
- Added path normalization before enforcement of uploads/{images,file}
prefix to prevent traversal at a path level.
Thanks to @Haxatron via huntr.dev for discovery and reporting.
