Security Flaw Found in Rently Smart Home Devices Could Expose User Data

CISA · 25 Aug 2026

Key Takeaway If your business uses Rently Smart Home systems, check for available security updates immediately and review who has access to your smart building controls.

CISA has disclosed a security vulnerability affecting Rently Smart Home systems (version 20.1.0 and earlier) that could allow attackers to access sensitive information and override user permission settings. The flaw, rated 8.1 out of 10 on the severity scale, stems from the system storing or handling login credentials in an insufficiently protected way, making them easier for attackers to obtain and misuse.

Rently provides smart home and access control technology used in commercial facilities, and the affected products are deployed in the United States and India. While there is no indication this vulnerability has been actively exploited, its high severity rating means businesses using Rently systems, particularly those managing rental properties, offices, or shared facilities, should treat this as a priority issue.

Businesses relying on smart locks, access systems, or connected building technology should check with their vendor or IT provider to confirm whether affected Rently software is in use and whether a patch or update has been released. Given the vulnerability allows both data exposure and permission tampering, unpatched systems could let unauthorised users gain elevated access to building controls.
