CERT Polska coordinated disclosure of CVE-2026-8990, an authentication bypass vulnerability in the Kidsview mobile application. An attacker with physical access to a smartphone can interact with the application's push notifications to bypass authentication controls and gain full access to the device owner's account. This vulnerability requires local access to the device, limiting its exploitability to scenarios where an adversary has physical possession of or proximity to the victim's smartphone.
The vulnerability was responsibly reported by security researcher Jakub Lewandowski and has been remediated by the vendor in Kidsview version 4.4.3. Users of the application should update to this version or later to eliminate the exposure.
While the attack vector requires physical access rather than remote exploitation, the complete authentication bypass represents a significant privacy and security risk for application users, particularly given Kidsview's nature as a parental control and monitoring solution.

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 16,570 reports from 147 sources, 725 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.
