CVE-2021-41149

Tough provides a set of Rust libraries and tools for using and generating the update framework (TUF) repositories. The tough library, prior to 0.12.0, does not properly sanitize target names when caching a repository, or when saving specific targets to an output directory. When targets are cached or saved, files could be overwritten with arbitrary content anywhere on the system. A fix is available in version 0.12.0. No workarounds to this issue are known.
