Miggo AIRoot Cause Analysis

The vulnerability stems from improper handling of ZIP file extraction in ziptil.go, as explicitly referenced in the GitHub issue. The attack vector involves crafting ZIP files with path traversal sequences, which would be processed by the ZIP extraction logic. The function responsible for writing extracted files (likely ExtractOrCreateFile) fails to validate/sanitize file paths, allowing attackers to write arbitrary files to any location. This matches the CWE-434 pattern and the described exploit mechanism.
