Home Assistant Community Store (HACS) prior to 1.10.0 contains a path traversal vulnerability that allows unauthenticated attackers to read sensitive files by traversing directories via the /hacsfiles/ endpoint. Attackers can retrieve the .storage/auth file containing user credentials and refresh tokens, then craft valid JWT tokens to gain administrative access to Home Assistant instances.
