    "summary": "boneIO Black does not limit authentication attempts on its web interface (POST /api/login) or SSH service, and does not enforce password complexity. An unauthenticated remote attacker can make unlimited brute-force login attempts, potentially compromising user accounts and gaining unauthorized access to the device. This issue was fixed in version 1.6.0: web login attempts are rate-limited per source address and per account, panel passwords must be at least 8 characters long, and SSH allows three authentication attempts per connection with a shortened login grace time.",
