## Technical details

A path traversal flaw in an optional, non-default administrative feature fails to properly neutralize special pathname elements (CWE-22), allowing authenticated administrators to move files to locations outside the feature's designated directory. The vulnerability is exploitable over the network with high privileges required and no user interaction, potentially enabling arbitrary code execution through file placement in sensitive system directories. The fix is available in version 9.5.0.
