  "summary" : "SFTPGo source-side file-pattern filter bypass during copy operations",
  "details" : "### Summary\n\nFile pattern filters (`denied_patterns` / `allowed_patterns`) were evaluated on the destination of a copy only. A user holding the copy permission could copy a file denied by the filters to a permitted name and then read it. A recursive directory copy reproduced the contents of a restricted directory under a path where the filters do not deny them, and the hide policy was affected in the same way: a file reported as missing by stat and by directory listings could still be copied.\n\n### Details\n\nAn authenticated user can read the contents of files that the file pattern filters are configured to deny them. Nothing else is bypassed: the home directory, the virtual folder layout and the per-directory permissions are all still enforced, and both ends of the copy are paths the account can already reach. No access to other accounts and no administrative capability.",
