No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

In Progress ShareFile Storage Zones Controller versions <= 5.12.5 and <= 6.0.2, an authenticated zone administrator can exploit improper validation in the download preparation flow, enabling attacker-controlled files to be written outside the intended preparation directory. This can lead to remote code execution in v5 versions. Remote code execution is not confirmed on v6 versions.
