SoftIron HyperCloud 2.5.0 through 2.6.3 may incorrectly add user SSH keys to the administrator-level authorized keys under certain conditions, allowing unauthorized privilege escalation to admin via SSH. Affects non-production debug and internal development builds created between versions 2.5.0 and 2.6.3. No generally available (GA) or customer-released production builds were affected. There is no evidence that this issue was exposed in customer environments or production deployments.
The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor.
