CVE-2026-64825
Home Assistant Core vulnerable to Path Traversal via backup upload during onboarding
Sévérité par source
Le label propre à Trivy est CRITICAL. Critique selon GHSA.
Description
Home Assistant Core before 2026.6.0 contains a path traversal vulnerability that allows unauthenticated attackers to write arbitrary files to any directory on the host filesystem by uploading a crafted backup archive during the initial onboarding window. Attackers can manipulate the 'name' field inside the uploaded archive's backup.json to supply an absolute path, causing pathlib.Path.__truediv__ to discard the configured backup directory prefix and write attacker-controlled content to arbitrary locations, with full filesystem access when the process runs as root.
