+# Arbitrary file write from downloading malicious torrents
+
+File paths from torrent metadata were not sanitized properly in `vortex-bittorrent`. A malicious torrent could exploit path traversal or symlink following to cause the library to create or write to files outside the intended download directory.
+
+This could allow an attacker to overwrite existing files that the application has permission to read and write, provided the torrent's corresponding data is downloaded.
+
+This was fixed in version 0.8.0 which adds validation to file paths and directory relative filesystem operations.
