CVE-2025-56558 (GCVE-0-2025-56558)

Vulnerability from cvelistv5 – Published: 2025-10-29 00:00 – Updated: 2026-01-08 18:17 Disputed Exclusively Hosted Service
VLAI?
Summary
The Dyson MQTT server (2022 and possibly later) allows publications and subscriptions by a client that has the correct values of AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, and device serial number, even if a device (such as a Pure Hot+Cool device) has been removed and is not visible in the supported MyDyson app. This could allow an unexpected actor to obtain control and set the room temperature (up to 37 Celsius) if ownership of the device is transferred without wiping the device. NOTE: the Supplier's position is that this is "a potential vulnerability that dates back 4 years ago in 2022 and we are unable to replicate that anymore."
