_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed WS_FTP Server version in the admin console or on the server.
- Review which accounts hold folder-management permissions.

## Fix

- Move to WS_FTP Server `2025.0.5` or later.

## Timeline

- 2026-11-09T17:27:38+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-115337

## From the sources

Improper access control in Progress WS_FTP Server versions prior to 2025.0.5 could allow an authenticated user with certain folder-management permissions to bypass access restrictions and access or modify files belonging to other users.
