Last modified

CVE-2020-12859 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. Unnecessary fields in the OpenTrace/BlueTrace protocol in COVIDSafe through v1.0.17 allow a remote attacker to identify a device model by observing cleartext payload data. This allows re-identification of devices, especially less common phone models or those in low-density situations.. EPSS estimates a 0.69% chance of exploitation in the next 30 days.

Description
