CISA and Rockwell Automation disclosed a path traversal vulnerability (CVE-2026-11917) in ThinManager, software used to manage thin clients in industrial environments across chemical, critical manufacturing, energy, food and agriculture, and water/wastewater sectors worldwide. The flaw stems from improper limitation of file save operations within the application's API, allowing an authenticated attacker to write arbitrary files to restricted system directories outside the application's intended directory (CWE-22).
Multiple ThinManager version branches are affected, including 13.0.0-13.0.6, 13.1.0-13.1.4, 13.2.0-13.2.3, and 14.0.0-14.0.1. Rockwell has released corrected versions (13.0.8, 13.1.6, 13.2.5, and 14.0.3) addressing the issue. CISA reports no known public exploitation of this vulnerability at this time and credits Rockwell Automation for responsibly reporting it.
Organizations using affected versions should prioritize upgrading to the patched releases. Where immediate patching isn't feasible, CISA recommends standard ICS defense-in-depth measures including network segmentation, isolating control system networks from business networks and the internet, and using secure remote access methods such as VPNs.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,433 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
