Description

The unarchive internal module&#39;s archive extraction commands perform no code-level validation on extracted file paths, relying entirely on the behavior of external tools (e.g. GNU tar) which varies by platform. While CVE-2025-10284 addressed git-specific RCE vectors, the underlying archive extraction path traversal was never fixed. On systems with GNU tar
