CVE-2020-14030
By generating (and writing to the disk) malicious .NET serialized files, an attacker can trick the product into deserializing them, resulting in arbitrary code execution.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.84%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
