CVE-2026-64824 Details
Description
Home Assistant Core before 2026.7.0 contains a path traversal vulnerability in the backup-restore function that allows attackers to write files to arbitrary absolute filesystem paths by supplying a crafted tar archive with a SYMTYPE entry containing a benign member name paired with an absolute linkname pointing outside the extraction directory. 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.
A path traversal vulnerability has been identified in Home Assistant Core versions prior to 2026.6.0. This vulnerability exists in the backup-restore function, where attackers can write files to arbitrary absolute filesystem paths. Exploitation involves sending a crafted tar archive with a SYMTYPE entry that includes a harmless member name and an absolute linkname pointing outside the extraction directory. The official Docker image runs Home Assistant as root, allowing attackers to achieve remote code execution by overwriting critical Python files or custom component directories.
Users should update to Home Assistant Core version 2026.6.0 or later, where this vulnerability has been patched.
