CVE-2026-93694 · Severity: medium · CVSS 4 · Published 2026-10-12

Progress ShareFile Storage Zones Controller, used by enterprises to manage file storage and sharing, accepts queue item acknowledgements from unvalidated callback URLs. Combined with a race condition, an attacker controlling copy queue work can manipulate the file copy service to process attacker-controlled data, potentially writing files to arbitrary locations on the server.

## How to fix

- Fixed in v5.12.7, v6

## Technical details

Queue item processing in Storage Zones Controller v5.12.6 and below sends acknowledgements to unvalidated callback URLs without proper validation. A race condition in the FileCopyService allows an attacker with control over copy queue work items to inject malicious metadata and content. The vulnerability requires the attacker to control the copy queue and exploit the timing of the race condition; when chained with other vulnerabilities (CVE-2026-93693, CVE-2026-93695), unauthenticated remote code execution is possible.
