Because the official Docker image runs the Home Assistant process as root and the subsequent regular-file entry is written through the unvalidated symlink, attackers can achieve remote code execution by overwriting auto-imported Python paths such as site-packages/sitecustomize.py or custom component directories.\n\n## Affected\n\n- `home_assistant_core < 2026.7.0`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":58,"depthScoreParts":{"impact":46.2,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[]}
