GHSA-f396-4rp4-7v2j: Boxlite: Path Traversal Vulnerability Leads to Arbitrary File Write on the Host

Boxlite, a sandbox service for running containers, has a path traversal vulnerability (a security flaw where attackers can access files outside intended boundaries) in how it extracts container images. When processing tar files (compressed archives), Boxlite doesn't validate symlink targets (shortcuts to files or directories), allowing an attacker to create a malicious container image that writes files anywhere on the host system, potentially leading to remote code execution (running unauthorized commands on the computer).
