   There is also a path-boundary issue in the new local repository import. The 
allowed-path check is applied to the requested location, but traversal follows 
symbolic links inside that directory. A ConfigSet editor can therefore cause 
the import to read outside the intended allowed paths when the local repository 
contains such a link. The single-file import has the same concern. This depends 
on the local repository contents and the caller's ConfigSet permissions.
   
   The earlier [offered 
patch](https://github.com/apache/solr/pull/5287#issuecomment-6653195270) 
includes path checks and symlink regression tests. The PR has since gained a 
documentation commit, so the old fast-forward command in that comment is no 
longer valid at the current PR head. I'm preparing an updated branch on the 
current head for Linux verification; no new test result is available yet.
