CERT Polska coordinated the disclosure of CVE-2026-40127, an Authorization Bypass Through User-Controlled Key vulnerability affecting OutSystems Lifetime. The flaw resides in the ApplicationID parameter, which any authenticated user could manipulate to access the Change Log of applications they are not authorized to view, exposing action histories performed by other users as well as application names.
The vulnerability was responsibly reported by Zbigniew Piotrak of the AFINE Team and has since been remediated by OutSystems in Lifetime version 11.28.2.3955. There is no indication of active exploitation; this is a coordinated disclosure with a patch already available. Organizations running OutSystems Lifetime should update to the fixed version to prevent unauthorized users from enumerating application metadata and audit log details.

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.
