CyberRota Analysis
AI-GeneratedBlueprint Studio versions prior to 2.5.2 are vulnerable due to improper handling of SSH private keys, which are temporarily written to the Home Assistant configuration directory without adequate cleanup measures. This could allow an attacker with filesystem access to retrieve sensitive private key material, potentially compromising the security of the system. Users running affected versions should prioritize updating to 2.5.2 or later to mitigate this risk.

Original NVD Description
Blueprint Studio is a VS Code-like file editor for Home Assistant configuration files. Prior to 2.5.2, Blueprint Studio terminal SSH key authentication in custom_components/blueprint_studio/backend/terminal_manager.py wrote SSH private-key material to a file under the Home Assistant configuration directory before applying restrictive permissions and relied on best-effort cleanup. The key could temporarily remain on disk and could persist if cleanup failed or Home Assistant crashed. A user or process with filesystem access to the Home Assistant configuration directory could obtain the residual private key. This issue is fixed in version 2.5.2.
