- Exploitation
- No exploitation in the wild and no public exploit is recorded for the CVEs named.
CISA issued an advisory detailing three vulnerabilities affecting Rockwell Automation's Studio 5000 Logix Designer, a widely used engineering tool for programming Rockwell PLCs in critical manufacturing environments worldwide. The flaws span multiple version ranges from V32.00 through V36.00 and include a path traversal issue in ACD project file handling (CVE-2026-9108), an incorrect authorization flaw allowing authenticated users to redirect external tool paths to malicious executables (CVE-2026-9127), and an unquoted search path vulnerability that could allow execution of attacker-planted binaries (CVE-2026-9128).
All three vulnerabilities require local access or user interaction and have high attack complexity, and CISA states no known public exploitation has been reported. Rockwell has released fixed versions (V32.05, V33.03/04, V34.02/03/04, V35.01/02, V36.01, and V37.00) addressing the respective CVEs, and recommends organizations unable to upgrade immediately follow vendor-published security best practices. The advisory is standard vendor-disclosed patching guidance for the critical manufacturing sector with no evidence of active exploitation or threat actor involvement.

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 16,436 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.
