CVE-2019-18827
On Barco ClickShare Button R9861500D01 devices (before firmware version 1.9.0) JTAG access is disabled after ROM code execution.
Does this matter?
Lower severity and a low EPSS score (1.35%). Track it; it rarely justifies an emergency change on its own.

On Barco ClickShare Button R9861500D01 devices (before firmware version 1.9.0) JTAG access is disabled after ROM code execution. This means that JTAG access is possible when the system is running code from ROM before handing control over to embedded firmware.
