CISA published an advisory for a vulnerability in Johnson Controls' XAAP Android application (Fire Solutions), tracked as CVE-2026-34490. The app stores application data locally on the device without encryption, meaning an attacker who already has physical access to the device—or who has compromised it through a separate, unrelated flaw—could read the stored data in plaintext. The issue is classified under CWE-312 (Cleartext Storage of Sensitive Information) and requires no network access, limiting exploitation to the local device environment.
The vulnerability affects all versions of XAAP Android prior to 1.53, deployed worldwide across the Critical Manufacturing sector. Johnson Controls has released version 1.53 to remediate the flaw and recommends additional mitigations including restricting physical device access, enforcing Android OS hardening and device encryption, deploying MDM solutions, and avoiding rooting or jailbreaking of production devices. No public exploitation of this vulnerability has been reported to CISA at this time, and the flaw cannot be exploited remotely, limiting its overall real-world urgency.

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 16,566 reports from 147 sources, 722 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.
