Miggo AIRoot Cause Analysis

The vulnerability stemmed from missing path sanitization in archive extraction handlers. The pre-patch code in rar.go, tar.go, and zip.js directly concatenated user-controlled filenames (header.Name/zf.Name) with the target directory without validating the resolved path. The commit introduced sanitizeExtractPath to check if the destination path remains nested within the target directory. The affected functions are clearly the extraction handlers in these files, as they lacked this critical check before the patch.
