CISA disclosed a vulnerability (CVE-2026-75960) affecting Rently Smart Home versions 20.1.0 and prior, classified as Insufficiently Protected Credentials (CWE-522). Successful exploitation could allow an attacker to retrieve sensitive PIN data, including the Master Pin, effectively overriding standard user permission controls on affected smart home/lock systems. This could have significant physical security implications for residential or commercial properties relying on Rently's smart access products.
The vulnerability affects devices deployed primarily in the United States and India, with Rently headquartered in the U.S. The affected sectors per CISA's designation include Commercial Facilities, Communications, and Information Technology. Rently patched the issue in late June, and no user action is required beyond ensuring devices have received the update. CISA states there is no known public exploitation of this vulnerability at this time.
The vulnerability was responsibly reported to CISA by researcher Berk Dusunur. CISA's standard ICS mitigation guidance applies: minimizing network exposure of control system devices, isolating them behind firewalls, and using secure remote access methods such as VPNs where necessary.

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 its extracted indicators and 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.
