CVE-2026-93695

Arbitrary file write via uncontained temporary file paths

Published Oct 12, 2026 · Updated Oct 12, 2026

Path traversal in Progress ShareFile Storage Zones Controller 5.12.6 and earlier allows attackers to write files via remote identifiers. FileCopyService incorporates a remote file identifier into a local temporary path without enforcing directory containment. Exploitation requires control of returned file metadata and content; writes are limited by service-account permissions, and code execution requires a writable executable IIS-served directory.
