CERT Polska coordinated the disclosure of CVE-2025-11598, a vulnerability in the mObywatel iOS application that allowed unauthorized access to personal information through the iOS App Switcher feature. The flaw enabled an attacker with physical access to view the account owner's personal data in the minimized app window even after the login session had ended, though reopening the app would require re-authentication. The specific data exposed depended on which screen was displayed before the application was minimized.
The vulnerability was responsibly reported by Maciej Krakowiak of DSecure.me and has been remediated in mObywatel version 4.71.0. This issue represents a privacy exposure risk rather than a remote exploitation vector, requiring physical access to an unlocked device to exploit. Users of the mObywatel iOS application should update to version 4.71.0 or later to address this vulnerability.

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.
