panda-py commands a robot arm in real time. Anything that can make the robot
move unexpectedly, or that lets code influence the control loop, is in scope,
as is anything affecting the Desk client, which handles credentials and
control tokens for the robot's web interface.
Note that the Franka Control Interface has no authentication of its own: any host that can reach the robot on the network can control it. Keeping the robot on an isolated network is part of a normal installation, not a vulnerability in panda-py.
Fixes go onto the latest release. Because a wheel is tied to the libfranka version it was built against, a fix generally means rebuilding the affected rows of the compatibility matrix rather than patching a single wheel.
