Upstream source description

FlexGet before 3.20.7 contains a path traversal vulnerability in the decompress plugin that allows remote attackers to write arbitrary files by supplying malicious archive member paths. Attackers can deliver zip or rar archives with ../ sequences or absolute paths through a feed, writing Python files into the plugins directory for code execution.
