Name of the Vulnerable Software and Affected Versions Hybrid Group Gobot versions prior to 1.13.0

Description The issue concerns the mqtt subsystem skipping verification of root CA certificates by default, allowing an attacker who can perform a man-in-the-middle (MITM) attack to read or forge messages between the client and server. This affects the github.com/hybridgroup/gobot/platforms/mqtt package.

Recommendations For versions prior to 1.13.0, update to version 1.13.0 or later to resolve the issue. As a temporary workaround, consider disabling the mqtt subsystem until a patch is available. Restrict access to the mqtt server to minimize the risk of exploitation. Avoid using the mqtt connection until the issue is resolved.
