Technical details
The vulnerability stems from case-sensitive string matching in the Rejected() authorization gate while the filesystem resolution is case-insensitive. An attacker sends a request with mixed-case path like /Admin/secret.lua; the permission check uses strings.HasPrefix() without normalization, so "/Admin" does not match the protected prefix "/admin" and falls through to public acceptance. The same path is then passed to the filesystem layer, which resolves it to the real admin/secret.lua on case-insensitive NTFS, APFS, or HFS+ filesystems, bypassing authorization entirely.
