Improper SSH Key Handling in Internal Debug Builds May Grant Cluster-Level Access to Non-Administrative Users

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.
