CVE-2021-3152 (GCVE-0-2021-3152)

Vulnerability from cvelistv5 – Published: 2021-01-21 15:10 – Updated: 2024-08-03 16:45 Disputed

Summary

Home Assistant before 2021.1.3 does not have a protection layer that can help to prevent directory-traversal attacks against custom integrations. NOTE: the vendor's perspective is that the vulnerability itself is in custom integrations written by third parties, not in Home Assistant; however, Home Assistant does have a security update that is worthwhile in addressing this situation
