Technical details
This vulnerability is a sensitive information disclosure (CWE-532) in the logging subsystem of Cisco RoomOS caused by improper logging of credentials and other sensitive data.

The attack requires user interaction (UI flag set) and network access to the device. Cisco has released fixed software versions addressing this vulnerability: RoomOS 11.39.1.3 or later for on-premises deployments, RoomOS 26.7.2.2 or later for cloud-aware deployments, and RoomOS June 2026 (26.7.1.12) or later for cloud deployments.
