# CVE-2026-93695: Arbitrary file write through remote file identifiers in Progress ShareFile Storage Zones Controller FileCopyService

- Severity: CVSS 7.4 (High), CNA
- Vector: CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Published: 2026-10-12 · Updated: 2026-10-13

## Affected

- Progress ShareFile Storage Zones Controller: through 5.12.6

## Description

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.
