CVE-2026-93695

HIGH 7.4

Published 2026-10-12 · Last modified 2026-10-13

In Progress ShareFile Storage Zones Controller v5.12.6 and below, FileCopyService uses a remote file identifier when constructing a local temporary file path without enforcing containment. This can cause FileCopyService to write attacker-controlled content to filesystem locations writable by the service account. This can result in remote code execution when an executable IIS-served directory is writable.
