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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.92%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
