CERT Polska coordinated the disclosure of three security vulnerabilities affecting STER software, reported by Michelin CERT. The most critical issue is CVE-2026-25606, a SQL injection vulnerability in multiple search filters that allows authenticated attackers to access sensitive data belonging to other users or any data accessible by the application. The second vulnerability, CVE-2026-25607, involves the use of a weak password encoding algorithm that enables attackers to reverse-engineer passwords by analyzing encoded values. The third issue, CVE-2026-25608, exposes users to man-in-the-middle attacks due to unencrypted TCP traffic transmission, potentially compromising passwords, personal data, and authentication tokens.
All three vulnerabilities have been addressed in STER version 9.5. Organizations using earlier versions should prioritize upgrading to mitigate these risks. The combination of SQL injection with weak password encoding and cleartext transmission creates a significant attack surface for both authenticated and network-adjacent attackers.

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.
